Boeing says problem with 737 MAX warning signal slipped through the cracks

Boeing says problem with 737 MAX warning signal slipped through the cracks

Boeing’s first 737 MAX 9 jet makes its appearance at the company’s Renton plant in 2017. (Boeing Photo) Boeing says a warning alert system that figures in the investigation of two catastrophic 737 MAX crashes didn’t work the way it was supposed to because of a software flaw that engineers identified a year before the accidents. The revelation adds a new twist to the debate over the company’s safety practices. In this case, the debate focuses on a feature known as the “AOA Disagree” alert, which is supposed to light up in the cockpit if there’s a mismatch in data coming from two angle-of-attack sensors on the plane. Investigators suggest that bad sensor data played a key role in October’s Lion Air crash in Indonesia, which killed all 189 people aboard the plane; and March’s Ethiopian Airlines crash, which killed 157. Within days of the Ethiopian crash, all 737 MAX airplanes were grounded worldwide. Boeing engineers knew about a problem with the “AOA Disagree” alert well before that. The alert was originally intended to be a standard feature on the 737 MAX and the previous generation of 737 planes, known as the 737 NG (for “Next Generation”). But in a , Boeing said that in 2017, several months after deliveries began, engineers became aware that the 737 MAX display system software didn’t meet the original requirements. “The software delivered to Boeing linked the AOA Disagree alert to the AOA indicator, which is an optional feature on the MAX and the NG. Accordingly, the software activated the AOA Disagree alert only if an airline opted for the AOA indicator,” Boeing said. The company said it followed standard procedure for reviewing the issue, and determined that neither the software-based angle-of-attack indicator nor the alert was necessary for safe operation of the airplane. “Accordingly, the review concluded, the existing functionality was acceptable until the alert and the indicator could be delinked in the next planned display system software update,” Boeing said. “Senior company leadership was not involved in the review and first became aware of this issue in the aftermath of the Lion Air accident.” That’s when Boeing discussed the issue with the Federal Aviation Administration. About a week after the Indonesia crash, Boeing and the FAA issued bulletins noting that both the angle-of-attack indicator and the alert system were optional. Last December, Boeing conducted a follow-up internal safety review, which confirmed the view that the absence of a warning alert did not present a safety issue. The findings of that review were shared with the FAA, Boeing said. Three months after the review, the Ethiopian crash occurred. In the wake of that crash, Boeing has said the “AOA Disagree” issue will be fixed before the 737 MAX returns to flight. “Boeing is issuing a display system software update, to implement the AOA Disagree alert as a standard, standalone feature before the MAX returns to service,” the company said in its statement. “When the MAX returns to service, all MAX production aircraft will have an activated and operable AOA Disagree alert and an optional angle of attack indicator. All customers with previously delivered MAX airplanes will have the ability to activate the AOA Disagree alert.” The statement adds context to earlier reports that the angle-of-attack alert system was available only as part of an optional software package. It’s debatable whether either of the crashes could have been avoided if the alert was available as a standard feature on the planes involved. In the Ethiopian case, the investigation suggests that the pilots knew about the issue surrounding the angle-of-attack sensors and their effect on the 737 MAX’s automatic flight control system — but were nevertheless unable to pull the plane out of its final dive. In any case, the questions surrounding what Boeing engineers knew and when they knew it seem sure to figure in the multiple investigations sparked by the crashes. U.S. Rep. Rick Larsen, D-Wash., told KOMO News that the FAA’s actions before and after the crashes will also be examined during a May 15 hearing before the House Subcommittee on Aviation, which he chairs. ”We need to first find answers to ensure the safety of the airplane, to ensure the FAA is doing the right thing, that Boeing is doing the right thing, and that’ll be our focus,” Larsen told KOMO on Saturday, a day before Boeing issued its statement.
Boeing estimates cost of 737 MAX troubles at a billion dollars and counting

Boeing estimates cost of 737 MAX troubles at a billion dollars and counting

5:05pm, 24th April, 2019
Boeing’s first 737 MAX makes its way through the assembly plant in Renton, Wash., in 2015. (Boeing Photo) Boeing’s first-quarter financial stats took a serious hit in the wake of two fatal crashes involving its bestselling plane, the 737 MAX. The company estimated the additional costs associated with grounding the 737 MAX fleet at $1 billion, but more uncertainty lies ahead. Boeing executives held off on providing updated financial guidance until the impact of the 737 MAX issue becomes clearer. Revenue: Boeing reported first-quarter revenue of $22.9 billion, which is 2 percent below the year-ago figure but in line with analysts’ expectations. The shortfall is due primarily to fewer deliveries of 737 jets. Earnings: Net earnings for the quarter amounted to $2.15 billion, which translates to adjusted earnings per share of $3.16. That’s 13 percent below what they were a year ago but from Zacks Investment Research. Word from the top: “Across the company, we are focused on safety, returning the 737 MAX to service, and earning and re-earning the trust and confidence of customers, regulators and the flying public,” Boeing CEO Dennis Muilenburg said in the company’s . “As we work through this challenging time for our customers, stakeholders and the company, our attention remains on driving excellence in quality and performance and running a healthy sustained growth business built on strong, long-term fundamentals.” Word on the Street: Boeing’s share price rose 0.36 percent to close at $375.46, apparently reflecting investor relief that the quarterly results weren’t worse. The stock’s value has fallen about 8.5 percent since the beginning of March, just before the fatal crash of an Ethiopian Airlines 737 MAX. Quarter highlights Boeing said the $1 billion in additional costs comes primarily from reducing the 737 production rate from 52 to 42 airplanes a month, a move that spreads fixed costs over a smaller number of planes. That toll could rise if the uncertainty surrounding the 737 MAX’s fate continues into the long term. Muilenburg said Boeing is making “steady process on the path to final certification for a software update for the 737 MAX.” That update is meant to address problems with an automatic flight control system that has been linked to the Ethiopia crash as well as last October’s fatal crash of a Lion Air jet in Indonesia. Muilenburg said the fix has been tested on more than 135 flights but didn’t give a timetable for winning certification from the Federal Aviation Administration. This week as saying certification could come as early as late May, potentially leading to a return to flight in mid-June. The process that led to the 737 MAX’s certification in 2017 is the subject of multiple investigations, including inquiries by the FAA, the Justice Department and the FBI, and a panel of experts convened by Boeing. But Muilenburg said “there was no surprise, or gap, or unknown here, or something that somehow slipped through a certification process.” Because of the focus on the 737 MAX situation, Muilenburg said Boeing hasn’t yet decided whether to go ahead with plans for a next-generation midsize airplane known as the New Mid-Market Airplane, the NMA or 797. But 777X production is moving ahead as planned, with the model’s first flight expected within months and the first 777X delivery due next year. Boeing Global Services, which was broken out as a separate business unit in 2017, brought in glowing financial results. First-quarter revenue increased 17 percent over the year-ago figure, to $4.6 billion. Boeing said the increase was driven primarily by higher volume across the portfolio, including , an aerospace parts distributor. Boeing Defense, Space & Security also served as a bright spot in the quarterly report: Revenues for that business unit amounted to $6.6 billion, which represents a 2 percent increase over the previous year’s first-quarter figures. The first seven KC-46 tankers were during the quarter — a milestone dimmed only slightly by . Boeing said its CST-100 Starliner space taxi has gone through “successful environmental testing,” calls for an uncrewed Starliner to make its first demonstration flight to the International Space Station for NASA no earlier than August, with the first crewed flight to follow by as early as late 2019.

(GeekWire Photo / Alan Boyle) In addition to praising Tiger Woods and pillorying Democrats, President Donald Trump had some words of advice on Twitter for Boeing, which is dealing with federal investigations in the wake of two catastrophic 737 MAX crashes. “What do I know about branding, maybe nothing (but I did become President),” , “but if I were Boeing, I would FIX the Boeing 737 MAX, add some additional great features, & REBRAND the plane with a new name. No product has suffered like this one. But again, what the hell do I know?” What, indeed? In 1988, Trump acquired 17 Boeing 727s and landing rights at airports in New York, Boston and Washington, D.C., from Eastern Air Lines’ shuttle operation. He added some additional features to the plane and rebranded the operation as the Trump turned the no-frills service into a luxury experience, right down to the gold-colored bathroom fixtures — but . Trump Shuttle fizzled out in 1992, in a haze of loan defaults, bank negotiations and acquisitions. The operational descendant of Trump’s airline is the American Airlines Shuttle, which no longer uses 727s. Instead, the service uses a mix of Embraer 175 and 190 jets, Airbus A319-100s and Boeing 737-800s. Those 737s come from the previous generation of Boeing’s 51-year-old 737 brand, and don’t have the MCAS automatic flight control system that’s been linked to the 737 MAX’s troubles. Boeing didn’t respond to Trump’s suggestions on Twitter, but there were plenty of wags who joked that he’d probably go for rebranding the plane as the 737 MAX planes have been grounded worldwide due to concerns surrounding the two fatal crashes, which occurred in Indonesia last October and in Ethiopia last month. Boeing has developed a software update that it says will head off any further problems related to the MCAS system, but regulators haven’t yet approved the update. Thus, the timing for getting hundreds of 737 MAX airplanes back up in the air is … up in the air. Over the weekend, American Airlines said it would extend its cancellations of 737 MAX flights through Aug. 19. “By extending our cancellations through the summer, we can plan more reliably for the peak travel season and provide confidence to our customers and team members when it comes to their travel plans,” American Airlines’ executives explained . Meanwhile, Boeing, the U.S. Department of Transportation and the Justice Department (in league with the FBI) are all conducting investigations into the 737 MAX certification process.

Boeing cuts back temporarily on 737 MAX production and plans to review design process

Boeing cuts back temporarily on 737 MAX production and plans to review design process

3:40pm, 5th April, 2019
The first 737 MAX 8 plane undergoes final assembly at Boeing’s Renton plant in 2015. (Boeing Photo) Boeing will reduce its monthly production rate for its single-aisle 737 jets from 52 to 42, starting in mid-April, CEO Dennis Muilenburg said today. In a statement, Muilenburg said he’s also asked the company’s board of directors to establish an internal committee to review Boeing’s policies and processes for airplane design and development. The moves come in the wake of this week’s preliminary findings from an investigation into the March 10 crash of an Ethiopian Airlines 737 MAX 8 plane that killed all 157 people on board. Less than five months earlier, a similar Lion Air 737 MAX crash in Indonesia killed 189 people. Those two incidents led to a worldwide suspension in 737 MAX flights. Both crashes were traced to the improper activation of an automated flight control system known as the Maneuvering Characteristics Augmentation System, or MCAS. The system, which was added to the 737 MAX to safeguard against stalls, relied on data inputs from a single angle-of-attack sensor — and in both cases, there were indications that the sensor was providing spurious data. The MCAS problems have in turn raised questions about the process by which the 737 MAX, the latest incarnation of a 51-year-old narrowbody design, was . The U.S. Department of Transportation and the Justice Department are conducting separate investigations into that process, which has also been the subject of congressional hearings. Boeing manufactures its 737 MAX 8 and 9 planes — as well as an earlier model known as the 737NG — at its plant in Renton, Wash. Muilenburg said the temporary reduction in the production rate would not affect employment levels. At one time, Boeing had planned to by the end of this year. Here’s : “As we work closely with customers and global regulators to return the 737 MAX to service, we continue to be driven by our enduring values, with a focus on safety, integrity and quality in all we do. “We now know that the recent Lion Air Flight 610 and Ethiopian Airlines Flight 302 accidents were caused by a chain of events, with a common chain link being erroneous activation of the aircraft’s MCAS function. We have the responsibility to eliminate this risk, and we know how to do it. As part of this effort, we’re making progress on the 737 MAX software update that will prevent accidents like these from ever happening again. Teams are working tirelessly, advancing and testing the software, conducting non-advocate reviews, and engaging regulators and customers worldwide as we proceed to final certification. I recently had the opportunity to experience the software update performing safely in action during a 737 MAX 7 demo flight. We’re also finalizing new pilot training courses and supplementary educational material for our global MAX customers. This progress is the result of our comprehensive, disciplined approach and taking the time necessary to get it right. “As we continue to work through these steps, we’re adjusting the 737 production system temporarily to accommodate the pause in MAX deliveries, allowing us to prioritize additional resources to focus on software certification and returning the MAX to flight. We have decided to temporarily move from a production rate of 52 airplanes per month to 42 airplanes per month starting in mid-April. “At a production rate of 42 airplanes per month, the 737 program and related production teams will maintain their current employment levels while we continue to invest in the broader health and quality of our production system and supply chain. “We are coordinating closely with our customers as we work through plans to mitigate the impact of this adjustment. We will also work directly with our suppliers on their production plans to minimize operational disruption and financial impact of the production rate change. “In light of our commitment to continuous improvement and our determination to always make a safe industry even safer, I’ve asked the Boeing Board of Directors to establish a committee to review our company-wide policies and processes for the design and development of the airplanes we build. The committee will confirm the effectiveness of our policies and processes for assuring the highest level of safety on the 737-MAX program, as well as our other airplane programs, and recommend improvements to our policies and procedures. “The committee members will be Adm. Edmund P. Giambastiani, Jr., (Ret.), former vice chairman, U.S. Joint Chiefs of Staff, who will serve as the committee’s chair; Robert A. Bradway, chairman and CEO of Amgen, Inc.; Lynn J. Good, chairman, president and CEO of the Duke Energy Corporation; and Edward M. Liddy, former chairman and CEO of the Allstate Corporation, all members of the company’s board. These individuals have been selected to serve on this committee because of their collective and extensive experiences that include leadership roles in corporate, regulated industries and government entities where safety and the safety of lives is paramount. “Safety is our responsibility, and we own it. When the MAX returns to the skies, we’ve promised our airline customers and their passengers and crews that it will be as safe as any airplane ever to fly. Our continued disciplined approach is the right decision for our employees, customers, supplier partners and other stakeholders as we work with global regulators and customers to return the 737 MAX fleet to service and deliver on our commitments to all of our stakeholders.”
Boeing vows to take all necessary safety steps after Ethiopia issues preliminary 737 MAX crash report

Boeing vows to take all necessary safety steps after Ethiopia issues preliminary 737 MAX crash report

6:00pm, 4th April, 2019
Boeing CEO Dennis Muilenburg sits behind pilots during a 737 MAX airplane flight that demonstrated the performance of a flight control software update. (Boeing Photo) Boeing executives said today that they would take all necessary steps to ensure the safety of the company’s 737 MAX airplanes, after issued a saying that an Ethiopian Airlines jet was felled last month due to the same sensor problem that caused a fatal crash in Indonesia less than five months earlier. The Ethiopian crash and last October’s Lion Air crash in Indonesia killed a total of 346 people and led to the worldwide grounding of Boeing’s 737 MAX airplanes. Like investigators in Indonesia, the Ethiopian investigators said an automated flight control system known as the Maneuvering Characteristics Augmentation System, or MCAS, forced the plane into a catastrophic dive. Boeing’s software-based MCAS system was added to the 737 MAX as a safeguard against stalling, but in both cases, investigators said a faulty sensor fed bad data into the system. The preliminary report on the Ethiopian crash, issued today, said the pilots tried Boeing’s recommended procedure for overriding the MCAS system but still failed to regain control of the plane. , Boeing CEO Dennis Muilenburg said it was apparent that the MCAS system added to what is already a high workload environment. “It’s our responsibility to eliminate this risk,” he said. “We own it, and we know how to do it.” We at Boeing are sorry for the lives lost in the recent 737 accidents and are relentlessly focused on safety to ensure tragedies like this never happen again. Watch the full video here: — Dennis A. Muilenburg (@BoeingCEO) Muilenburg said Boeing has nearly completed work on a software update that would “prevent an MCAS-related accident from ever happening again.” He expected the fix to be certified and implemented throughout the 737 MAX fleet in the weeks ahead. , Boeing Commercial Airplanes President and CEO Kevin McAllister said the company would “carefully review” the preliminary report from Ethiopian investigators, “and will take any and all additional steps necessary to enhance the safety of our aircraft.” Ethiopian Airlines and investigators at the National Transportation Safety Board and the Federal Aviation Administration reacted to the day’s developments on Twitter: |n Airlines Statement on the Preliminary Report of the Accident on ET 302 — Ethiopian Airlines (@flyethiopian) NTSB statement: The preliminary report issued Thursday April 4, 2019, by the Ethiopia Aircraft Accident Investigation Bureau presents the initial information developed during their investigation of the crash of flight 302.

Ethiopian jet’s data record deepens concern about 737 MAX safety procedures

Ethiopian jet’s data record deepens concern about 737 MAX safety procedures

1:08pm, 3rd April, 2019
Ethiopian Airlines Group CEO, Tewolde GebreMariam, visits the accident scene in Ethiopia hours after the March 10 crash. (Ethiopian Airlines Photo via Twitter) Readings from the recorders recovered from last month’s crash of an Ethiopian Airlines Boeing 737 MAX jet reportedly suggest that the pilots tried using the recommended procedure for overriding a balky automated flight control system — but that the system was re-engaged and forced the plane into its fatal dive. The reports by and , based on interviews with unnamed sources who have been briefed on the post-crash investigation’s preliminary findings, raise deeper questions about the safety of the flight control system, known as the Maneuvering Characteristics Augmentation System, or MCAS. Boeing added the MCAS system to the 737 MAX as a safeguard against stalling, but investigations into the Ethiopian crash on March 10 — and last October’s crash of a Lion Air 737 MAX in Indonesia — have focused on the possibility that spurious data from a single angle-of-attack sensor caused the system to force the planes into catastrophic nose dives. The Indonesia crash killed all 189 people on board, and the Ethiopian crash killed 157 people. In the wake of the crash in Ethiopia, all 737 MAX planes have been grounded worldwide. Boeing is working on a software update that it says should resolve the MCAS issue, but that fix is still thought to be weeks away. In the past, Boeing has stressed that pilots could remedy the scenario that led to the crashes by disconnecting the MCAS system and taking manual control of the jet’s stabilizer trim mechanism. But the latest reports quote sources as saying the Ethiopian Airlines pilots tried that procedure but didn’t fully execute it. Instead, the MCAS system was re-engaged, leading to the final, fatal plunge. The Journal’s sources speculated that pilots re-engaged the automated system because they couldn’t raise the nose using manual controls, while Reuters’ sources held out the possibility that the MCAS system could have re-engaged itself. a former Boeing flight control engineers, Peter Lemme, as saying that the pilots might have been stymied by excessive aerodynamic loads on the stabilizer trim control system. I *assume* the mistrim situation created excessive load opposing the manual jackscrew authority from the trim wheel. From what is reported, they must have tried to restore electric trim to get the stab to come up, but then MCAS swept in again. — Peter Lemme (@Satcom_Guru) This post includes a brilliant video showing the challenges with manual trim. The situation may be worse than portrayed, as stick shaker is going off, and the elevator feel shift will increase aft column “feel” forces as much as four times more than normal. — Peter Lemme (@Satcom_Guru) also laid out a scenario by which excessive loads could have foiled efforts to stabilize the jet. The Times noted chatter on an online aviation forum about an alternate procedure, outlined in a 1982 pilot training manual, that might have averted the manual lockup by repeatedly letting go of the control column and turning the cockpit’s stabilizer trim wheel manually. Boeing said it was premature to comment on the specifics of such reports. “We urge caution against speculating and drawing conclusions on the findings prior to the release of the flight data and the preliminary report,” the company said. The 737 MAX crashes are the subject of investigations in Ethiopia and Indonesia, with participation by Boeing, the Federal Aviation Administration, the National Transportation Safety Board and other entities. The FAA’s inspector general is conducting its own investigation into the process by which the 737 MAX was certified for flight, and the Justice Department has reportedly launched a grand jury investigation with participation by the FBI. Subpoenas have gone out to Lemme and other potential witnesses, .
Hearings on Boeing 737 MAX crashes focus on certification and pilot training

Hearings on Boeing 737 MAX crashes focus on certification and pilot training

7:11pm, 27th March, 2019
Acting FAA chief Daniel Elwell, NTSB Chairman Robert Sumwalt and Calvin Scovel, the Transportation Department’s inspector general, face a Senate panel during a hearing on airline safety. (C-SPAN Photo) Were airline pilots adequately trained on a catastrophic scenario involving the automatic flight control system for Boeing’s 737 MAX airplanes? And did the Federal Aviation Administration cede too much of its responsibility to Boeing when the system was certified as safe? Those are among the key questions that U.S. senators had for federal officials today during a pair of Capitol Hill hearings today. Meanwhile, Boeing brought about 200 pilots and airline industry officials to Renton, Wash., the base of operations for the company’s 737 program, to learn more about the changes being made in the wake of two fatal MAX crashes in Indonesia and Ethiopia. October’s killed all 189 people aboard, while this month’s killed 157. In both cases, investigators have focused on an automatic flight control system known as the Maneuvering Characteristics Augmentation System, or MCAS. The MCAS software system was added to the 737 MAX, the latest version of the 51-year-old 737 line, to compensate for the aerodynamic effects of a larger engine and guard against stalling. But preliminary findings from the Lion Air investigation suggest that spurious data from a single angle-of-attack sensor forced the MCAS to push the plane repeatedly into a nose dive. Investigators suspect the same scenario in the Ethiopia crash. Even before that crash, Boeing was working on a software update to address the bad-data scenario. At a Renton news conference, Mike Sinnett, Boeing’s vice president of product strategy and development, confirmed that the update would have the MCAS come into play only if both angle-of-attack sensors detected indications of a stall. The system would be activated only once, rather than repeatedly, and could more easily be counteracted manually by the pilot, . Tests of the software changes were on the agenda for this week’s Renton gathering. All 737 MAX planes are grounded worldwide due to concerns about the crash, resulting in continuing disruption and costs for airlines. But once the FAA and its counterparts in other countries give the go-ahead, the software update could theoretically be distributed in a matter of days. Sinnett also said pilots would receive half an hour of computer-based training on the MCAS software changes, but that no additional training in a flight simulator would be required. He said the training plan has been “provisionally approved” by the FAA. The training issue came up repeatedly today at a congressional hearing organized by the Senate Commerce Committee’s panel on aviation and space. Acting FAA Administrator Daniel Elwell told senators that he didn’t believe the MCAS system was specifically addressed in flight simulation training. He said regulators initially agreed with Boeing’s analysis that the system made “no marked difference in the handling characteristics” of the 737. But in light of the fatal crashes, Elwell said training procedures are “an area that we will look into very, very carefully.” At an earlier hearing, organized by the Senate appropriations subcommittee focusing on the Transportation Department and other agencies, Transportation Secretary Elaine Chao faced tough questions about regulatory oversight, or the potential lack thereof. During the certification process for the 737 MAX, Boeing drew up its own safety analysis of the changes made from the design for the previous 737 model. In an , The Seattle Times quoted unnamed sources as saying that the analysis downplayed risks associated with the MCAS system. One former FAA engineer said the agency’s review of Boeing’s analysis was “rushed to reach [a] certain certification date.” When Chao was asked about the relationship between Boeing and the FAA during certification, she insisted that the FAA was in charge of the process. “The FAA does not build planes. They certify. But this method of having the manufacturer also be involved in looking at these standards is really necessary, because … the FAA cannot do it on their own,” she said. “Having said that, I am of course concerned about any allegations of coziness.” Chao emphasized that safety is her department’s top concern, and noted that additional steps were being taken to respond to issues raised in the aftermath of the Lion Air and Ethiopian Airlines crashes. Last week, Chao asked the of the certification process for the 737 MAX, and that investigation is getting under way. This week, to suggest improvements in the FAA’s oversight and certification process. During this afternoon’s hearing, Elwell said the cooperative approach to aircraft certification was deeply ingrained in FAA procedures. If the agency were to do the job without delegating duties to manufacturers,, he said.
Report: Optional safety features for Boeing 737 MAX jets will be offered for free

Report: Optional safety features for Boeing 737 MAX jets will be offered for free

1:02pm, 25th March, 2019
Boeing employees surround the 10,000th 737 jet — a 737 MAX 8 built for Southwest Airlines — during a ceremony in Renton, Wash., in March 2018. (Boeing Photo) Two optional safety features that might help pilots head off a scenario that’s at the heart of investigations into two catastrophic crashes of Boeing 737 MAX jets will be available free of charge on new airplanes, . The features are an indicator that shows pilots the readings from two sensors that monitor an aerodynamic characteristic known as the angle of attack, and a “disagree light” that flashes when those sensor readings are at odds with each other. Spurious data from the angle-of-attack sensors are thought to have played a role in last October’s crash of a Lion Air 737 MAX 8 plane in Indonesia, which killed 189 people on board; and this month’s crash of an Ethiopian Airlines 737-8 in Ethiopia, which killed 157. The current leading theory is that in both cases, bad data from a single sensor caused an automatic flight control system — known as the Maneuvering Characteristics Augmentation System, or MCAS — to kick in repeatedly. MCAS was added to the 737 MAX’s control system to compensate for the aerodynamic effect of the model’s bigger engines and guard against an excessive upward lift and stall. But investigators suspect that, in the fatal crashes, the system forced the plane into a nose dive. In both cases, pilots complained about control problems minutes into their doomed flights. Today as saying he believed the MCAS system was activated on the Ethiopian jetliner, based on what he has learned about the investigation. Boeing says pilots can use a procedure to disengage the MCAS system in the event of a problem, but the procedure apparently did not come into play in the Lion Air or Ethiopian Airlines scenarios. Over the weekend, Boeing brought pilots and trainers to its 737 MAX facility in Renton, Wash., to discuss potential safety modifications to the plane and test out simulations of an MCAS problem scenario. The New York Times quoted sources as saying that pilots using the simulators were able to land their virtual planes safely. About 200 pilots, technical leaders and regulators are due to attend another session on Wednesday. “This is part of our ongoing effort to share more details about our plan for supporting the safe return of the 737 MAX to commercial service,” Boeing said in a statement. “We had a productive session this past Saturday and plan to reach all current and many future MAX operators and their home regulators.” Boeing is preparing to release a software update and revised training guidelines aimed at addressing the MCAS issue. Reportedly, one of the changes will involve having the MCAS system take in data from both angle-of-attack sensors instead of just one. Another change would reportedly limit the system’s ability to kick in repeatedly. The Journal said the changes . The debate over the 737 MAX safety features has touched on the plane’s hardware: Last week, The New York Times reported that the angle-of-attack indicator and the disagree light were optional features that operators had to pay extra for. But on Sunday, the Times said the disagree light would become standard on all new 737 MAX planes, and the indicator would be provided free of charge for customers who want it.
Report: Indonesia’s Garuda airline seeks to cancel 737 MAX order in wake of crashes

Report: Indonesia’s Garuda airline seeks to cancel 737 MAX order in wake of crashes

1:24pm, 22nd March, 2019
An artist’s conception shows a Garuda Airlines 737 MAX jet in flight. (Boeing Illustration) Indonesia’s national airline, , is saying it wants to cancel an order for 49 Boeing 737 MAX 8 jets, citing the effect of two catastrophic crashes on passenger confidence. The order, , has a list-price value of roughly $6 billion. Only one of the 50 MAX jets ordered back then has been delivered to date. In interviews with media outlets including , , , , and , Garuda officials cited consumers’ low confidence in the 737 MAX in the wake of crashes that killed , and . “Many passengers told us they were afraid to get on a MAX 8,” Reuters quoted Garuda CEO Aria Askhara as saying. Garuda’s request hints at the economic impact that the crashes could have going forward. Boeing’s 737 MAX jets have been grounded worldwide as the crash investigations continue. Preliminary data suggest that an automatic flight control system known as the Maneuvering Characteristics Augmentation System or MCAS played a role in both crashes. Boeing added the MCAS to the 737 MAX line as a safeguard against stalls, but spurious data from a single sensor that monitors air flow may have forced each plane into a dive. Reports relating to cockpit conversations suggest that the pilots on both flights , but apparently didn’t follow a specified procedure for turning off the MCAS system. One of the controversies surrounding the 737 MAX focuses on whether pilots were adequately trained about the MCAS and what to do if it malfunctioned. Another controversy has to do with indicators that Boeing can install on the plane to tell pilots that the suspect sensor system is providing mismatched data. The New York Times reported that the indicators. Boeing says it’s preparing to release a software upgrade aimed at addressing concerns about the MCAS system and the angle-of-attack sensors, and will change its pilot training program for the 737 MAX as well. The Transportation Department says it will for flight, and the FBI and Justice Department are . As of the end of February, Boeing , with 376 of those planes delivered. Deliveries have now been along with 737 MAX flights. Boeing says the 737 assembly lines at its plant in Renton, Wash., will be to “focus on completing work that was previously delayed.” Garuda’s request could be seen as the first publicly confirmed request for an order cancellation to be sparked by the crash controversies. However, analysts told Reuters that even before this month’s Ethiopian Airlines crash, Garuda was considering a shift in its airplane procurement plan. “We don’t want to use MAX jets … but maybe will consider switching it with another Boeing model of plane,” Garuda spokesman Ikhsan Rosan told AP. Boeing has declined to comment on Garuda’s cancellation request, but the airline says Boeing representatives are due to visit Jakarta next week for further discussions.
Transportation Department plans to audit certification process for Boeing 737 MAX

Transportation Department plans to audit certification process for Boeing 737 MAX

(Boeing Photo) In the wake of two catastrophic crashes that may have had a common cause, Transportation Secretary Elaine Chao today opened the way for an audit of the process that led the Federal Aviation Administration to certify Boeing’s 737 MAX 8 jets in 2017. Because of the similarities between the two crashes, 737 MAX jets have been grounded worldwide. Boeing and the FAA are reportedly facing multiple investigations, including the audit announced today. Chao formally requested the audit in a referral memo to the department’s Office of Inspector General. The audit is meant to “help inform the department’s decision making and the public’s understanding, and to assist the FAA in ensuring that its safety procedures are implemented effectively,” Chao wrote. It will be part of a continuing review of factors related to aviation certification, she said. In a tweet, Boeing said it would “fully cooperate” with the audit. The audit is likely to address claims that the FAA put too much reliance on Boeing’s own analysis if safety issues surrounding the 737 MAX during its years-long development. The MAX is the latest version of Boeing’s workhorse single-aisle passenger airplane, with engines that are larger and more fuel-efficient than the previous-generation 737. The heft of the engines changed the aerodynamic characteristics of the 737. To minimize the need for pilot retraining, Boeing developed an automatic control system, known as the Maneuvering Characteristics Augmentation System or MCAS, which was designed to keep the plane from stalling if it encountered extreme conditions. Investigators say the MCAS appears to have played a role in last October’s crash of a nearly new Lion Air 737 MAX 8 jet in Indonesia, which killed 189 people. And preliminary reports suggest that an Ethiopian Airlines 737-8 traced a similar flight profile before it crashed on March 10 in Ethiopia, killing 157. In both cases, pilots reported flight control problems just minutes after takeoff, and soon afterward, each plane went into a catastrophic nose dive. In the Lion Air case, investigators surmise that the MCAS system received spurious data from a single sensor that monitored the wings’ angle of attack. Boeing says pilots can follow a procedure to disengage the MCAS in the event of a malfunction, but the Lion Air pilots didn’t follow that procedure. This week, reports emerged that readings extracted from the flight data recorder on the Ethiopian plane pointed to a similar angle-of-attack issue. Also this week, reports in and the raised questions about the procedures that the FAA and Boeing followed during development of the 737 MAX. To expedite that development effort, Boeing conducted its own safety analysis for the MAX and submitted it to the FAA. The Seattle Times quoted sources as saying that the initial analysis downplayed the scope and persistence of the MCAS system, as well as the need for additional pilot training. Speaking on condition of anonymity, a former FAA safety engineer said there was “constant pressure” to review Boeing’s documents quickly. The Wall Street Journal said the Transportation Department will look into whether unwarranted shortcuts were taken during the certification process. A separate grand jury investigation was being directed by the Justice Department, the Journal reported, and congressional hearings are a near-certainty. Boeing says it will soon roll out a software update for the 737 MAX that limits operation of the MCAS, and issue new guidance for pilot training as well. But the fact that multiple investigations are in the works suggests that the software fix won’t immediately fix Boeing’s image problem. Even if the FAA clears the 737 MAX for flight, regulators in Canada and other countries outside the U.S. say they won’t take the FAA’s word but . Air Canada said it plans to . Rep. Adam Smith, D-Wash., whose district includes the Boeing plant in Renton where the 737 MAX is built, said today that he worries about the plane’s reliance on automatic control systems like the MCAS. “It’s like when you call information, it’s great to have all these different menus, but you always want to be able to press zero and talk to a human,” Smith said during an appearance at a quantum computing summit at the University of Washington. “When you’re setting up these machines, all else fails, you’ve got to be able to push a button and just operate the damn thing.”
Ethiopian jet’s data points to a system that was an issue for 737 MAX before the crash

Ethiopian Airlines employees conduct a memorial service on March 15 to pay tribute to colleagues and passengers who lost their lives in the March 10 crash of a Boeing 737 MAX 8 jet. (Ethiopian Airlines Photo) The latest word from the investigation of is that readings retrieved from the flight data recorder reportedly point to circumstances similar to those that surrounded a 737 MAX crash less than five months earlier in Indonesia. Regulators around the world suspected as much, based on data received via satellite from the plane during its minutes-long flight from Addis Ababa heading for Kenya on March 10. That’s what led them to last week. The March 10 crash killed all 157 people aboard Ethiopian Airlines Flight 302, while the October crash killed all 189 people aboard Lion Air Flight 610. In the Lion Air investigation, safety experts focused on an automatic flight control system known as the Maneuvering Characteristics Augmentation System, or MCAS. Boeing added the MCAS system to the 737 MAX to guard against having the airplane stall under extreme conditions. The measure was taken because the MAX’s engines are bigger than the engines on the previous line of 737s, changing the aerodynamics. Preliminary findings from the Indonesia probe suggested that the MCAS system was receiving spurious data about the plane’s aerodynamic “angle of attack” just after takeoff. That would lead the automatic system to force the plane’s nose downward into an uncalled-for dive. In the Lion Air case, the pilots repeatedly fought against the MCAS commands — and ultimately lost. Afterward, Boeing said pilots can use a procedure to disengage the MCAS system, but that procedure wasn’t followed by the Lion Air pilots. Today, Reuters quoted an unnamed source as saying the angle-of-attack readings from the Ethiopian Airlines jet’s flight data recorder were “very, very similar” to the Lion Air readings. The similarities will be the focus of further investigation, Reuters quoted its source as saying. The double disaster has raised deeper questions about the Federal Aviation Administration’s oversight of Boeing during the certification of the 737 MAX. Over the weekend, The Seattle Times quoted sources as saying that assessing the MCAS system’s safety. The Times said those analyses understated how much leeway the automatic system was given to move the horizontal tail in order to avoid a stall — or force a dive if the system malfunctioned. Another potential flaw with the system was that it depended on readings from a single angle-of-attack sensor, rather than multiple sensors. Much of The Seattle Times’ report was based on research conducted before the Ethiopian Airlines jet crashed. Aerospace reporter Dominic Gates wrote that “both Boeing and the FAA were informed of the specifics of this story and were asked for responses” a few days before the crash. People shouldn’t misread this point. I was not telling Boeing or the FAA anything they didn’t know.As noted, Boeing has been working since the first crash on a fix for the flaws my story listed — Dominic Gates (@dominicgates) In a , Boeing CEO Dennis Muilenburg said that “safety is at the core of who we are at Boeing” and that the company is working with authorities and airlines to support the investigation and “help prevent future tragedies.” “Soon we’ll release a software update for the 737 MAX that will address concerns discovered in the aftermath of the Lion Air Flight 610 accident,” Muilenburg said. That update, and revisions in pilot training procedures, should address the MCAS’ behavior in response to erroneous sensor inputs, Boeing says. that Justice Department and Transportation Department officials are reviewing how the 737 MAX was developed, and how the plane won its regulatory approvals. it gave to 737 MAX jets. U.S. Sen. Roger Wicker, R-Miss., has said he intends to hold a hearing into the issues raised by the crashes, in his capacity as the chairman of the Senate Commerce, Science and Transportation Committee. The committee’s ranking Democratic member is Sen. Maria Cantwell, D-Wash. She touched on the matter briefly in response to a question today at the . “Paramount in all of this is safety,” Cantwell told GeekWire. “So we’re going to keep looking at all the data and information until we are sure that we understand every aspect of this.”

An artist’s conception shows a Southwest Airlines 737 MAX taking to the air. (Boeing Illustration) The Federal Aviation Administration today ordered the temporary grounding of Boeing’s next-generation 737 MAX jets, due to “new evidence” collected at the site of Sunday’s Ethiopian Airlines crash as well as satellite data. “The grounding will remain in effect pending further investigation, including examination of information from the aircraft’s flight data recorders and cockpit voice recorder,” the FAA : statement on the temporary grounding of 737 MAX aircraft operated by U.S. airlines or in a U.S. territory. — The FAA (@FAANews) Southwest Airlines operates , American Airlines has 24 MAX 8’s and United Airlines has 14 MAX 9’s, accounting for nearly 300 daily flights in all. Today’s announcement, which affects all 737 MAX aircraft operated by U.S. airlines or in U.S territory, came after scores of other nations took similar measures. The move was signaled in advance by President Donald Trump, and came just hours after Canadian Transport Minister Marc Garneau said 737 MAX planes would be barred from arrivals, departures and overflights in Canada. Garneau said satellite data suggested there were similarities between the flight profiles for the 737 MAX 8 involved in the Ethiopian Airlines crash that killed 157 people on Sunday and a , killing 189 people. In both cases, the pilots reported control difficulties just after takeoff, and the planes nose-dived shortly afterward. Garneau said the satellite readings were not conclusive, and he shied away from saying definitively that the crashes were related. “But it is something that points possibly in that direction, and at this point we feel that that threshold has been crossed and that is why we are taking these measures,” he said. Air Canada operates 24 of the 737-8 jets, while WestJet has 13 of the planes and Sunwing has four. Air Canada said that it was but that there may be delays. Preliminary findings from the Lion Air investigation focused on an automatic flight control system known as the Maneuvering Characteristics Augmentation System or MCAS. The system is designed to keep the 737 MAX from stalling under extreme aerodynamic conditions, but investigators said spurious sensor data may have caused the MCAS to put the Lion Air plane into an unwarranted dive. Boeing has laid out a procedure that pilots can use in such a scenario to switch off the MCAS system; however, that procedure wasn’t followed by the Lion Air pilots. The FAA says Boeing is due to upgrade the MCAS software next month. Today’s FAA announcement marked a rapid about-face: On Tuesday, the agency that it saw “no basis to order grounding” 737 MAX airplanes, and that no other civil aviation authorities had furnished data that would warrant further action. The 737 MAX is the latest incarnation of Boeing’s best-selling jet, and the company insists that the planes are safe. But in a , Boeing said it supported the decision: “Boeing continues to have full confidence in the safety of the 737 MAX. However, after consultation with the U.S. Federal Aviation Administration (FAA), the U.S. National Transportation Safety Board (NTSB), and aviation authorities and its customers around the world, Boeing has determined — out of an abundance of caution and in order to reassure the flying public of the aircraft’s safety — to recommend to the FAA the temporary suspension of operations of the entire global fleet of 371 737 MAX aircraft. ” ‘On behalf of the entire Boeing team, we extend our deepest sympathies to the families and loved ones of those who have lost their lives in these two tragic accidents,’ said Dennis Muilenburg, president, CEO, chairman of the Boeing Company. ” ‘We are supporting this proactive step out of an abundance of caution. Safety is a core value at Boeing for as long as we have been building airplanes; and it always will be. There is no greater priority for our company and our industry. We are doing everything we can to understand the cause of the accidents in partnership with the investigators, deploy safety enhancements and help ensure this does not happen again.’ “Boeing makes this recommendation and supports the decision by the FAA.” Check back for updates to this developing story, first published at 10:49 a.m. PT March 13.

Air Canada joins the list of carriers grounding their 737 MAX planes. (Air Canada Photo) Canada today joined scores of nations in suspending flights of Boeing 737 MAX jets, out of concern that two catastrophic 737 crashes might be related. The move by Transport Minister Marc Garneau leaves the United States and the Federal Aviation Administration increasingly isolated in its stance that the 737 MAX 8 and MAX 9 jets are airworthy and that no further safety measures are needed at this time. Boeing 737-8 and 737-9 planes are barred from arrivals and departures in Canada, and will not be allowed to fly over the country until further notice, Garneau said. Air Canada operates 24 of the 737-8 jets, while WestJet has 13 of the planes and Sunwing has four. Air Canada said that it was but that there may be delays.

The FAA says Boeing is due to upgrade the MCAS software next month. Concerns about a potential link between the two fatal crashes have led to widespread groundings of the 737 MAX, the latest incarnation of Boeing’s best-selling plane. China and the European Union have been joined by nations ranging from Mexico to Oman. On Tuesday, the FAA issued a statement saying that it saw “no basis to order grounding” 737 MAX airplanes, and that no other civil aviation authorities have furnished data that would warrant further action: UPDATED Statement regarding 737 MAX. — The FAA (@FAANews) Boeing said it had no new guidance to offer to 737 MAX operators. “We understand that regulatory agencies and customers have made decisions that they believe are most appropriate for their home markets,” the company said in a statement Tuesday. “We’ll continue to engage with them to ensure they have the information needed to have confidence in operating their fleets.” The black-box recorders from Ethiopian Airlines Flight 302 have been recovered, but there’s no word yet about what was found in the cockpit recordings or flight data.

The first Boeing 737 MAX 8 jet delivered to Ethiopian Airlines takes off in July 2018. (Boeing Photo) The Federal Aviation Administration today responded to concerns over Boeing 737 MAX 8 jets by reassuring airlines that the planes were airworthy, despite the fact that the model was involved in two catastrophic fatal accidents in the past five months. , just minutes after the takeoff of Ethiopian Airlines Flight 302, heading from Addis Ababa in Ethiopia to Nairobi in Kenya. In its the FAA acknowledged that many reports have pointed out similarities to the , in which 189 people dled. “However, this investigation has just begun and to date we have not been provided data to draw any conclusions or take any actions,” the notification said. Airlines in China, Ethiopia, Indonesia and several other countries grounded their 737 MAX 8 jets, pending verification that the planes are safe. It’s not yet clear what effect the FAA’s confirmation of airworthiness will have on those suspensions in service. The FAA has dispatched experts to assist Ethiopian investigators on the ground, Experts from the National Transportation Safety Board, GE Aviation, Boeing and Kenya’s civil aviation agency are on the case as well. “All data will be closely examined, and the FAA will take appropriate action if the data indicates the need to do so,” the FAA said. focused on an automatic control system known as the Maneuvering Characteristics Augmentation System, or MCAS. The system is meant as a safeguard to keep the plane from stalling under extreme aerodynamic conditions, but there were some signs that the system on the Lion Air 737-8 was receiving spurious data from an angle-of-attack sensor. Today’s notification reviewed actions taken by the FAA to ensure that Boeing’s prescribed safety procedures were adequate. The FAA also noted that some actions are still in process.

Ethiopian Airlines reported today that both of the “black boxes” from the 737-8 that crashed — the cockpit voice recorder and the flight data recorder — . However, as saying that one of the recorders was partially damaged. “We will see what we can retrieve from it,” the official told AP. Sunday’s crash killed all 157 people aboard the plane, including . Many of those workers were in Nairobi, Kenya. It was the second fatal accident involving the 737-8 model in less than five months. The earlier crash. , China’s Civil Aviation Administration said it was issuing its suspension notice “in view of the fact that the two air crashes were newly delivered Boeing 737-8 aircraft, and they all occurred in the takeoff phase.” The agency said it would consult with Boeing and the U.S. Federal Aviation Administration and let Chinese airlines know when flights can be resumed. Separately, Ethiopian Airlines, which has four 737 MAX 8’s remaining after Sunday’s crash, said it would Indonesia for inspections. And Cayman Airlines said it was “until more information is received.” Boeing is participating in the Ethiopia crash investigation but said it had no new guidance for airplane operators: Breaking: In statement to CNN, Boeing says no new safety guidance planned for now on : “At this point, based on the information available, we do not have any basis to issue new guidance to operators.” — Jim Sciutto (@jimsciutto) The crash forced the at its factory in Everett, Wash. “Boeing is deeply saddened by the Ethiopian Airlines Flight 302 accident and our focus is on supporting our customer,” company spokesman Paul Bergman said in an email. “In light of this, we are postponing the 777X external debut on March 13 and the related media events.

He said Boeing and Ethiopia’s Accident Investigation Bureau would take part in the crash investigation. The U.S. National Transportation Board said it was , with assistance from the Federal Aviation Administration and GE. Kenyan investigators were on their way as well.

GebreMariam said the pilot reported difficulties just after takeoff from Bole International Airport. The pilot reportedly sought, and was given, permission to return to the airport — but contact was lost at 8:44 a.m., six minutes into the flight.
