MCAS takes readings from two sensors that determine how much the plane’s nose is pointing up or down relative to oncoming airflow. Boeing will pay $2.5 billion to settle a criminal charge of defrauding safety regulators in connection with the development of the 737 Max aircraft, which suffered two deadly crashes. For example, at 05:37:53 local time, the crew engaged the automatic takeoff and climb sequence. November 18, the FAA announced that the MAX had been cleared to return to service in U.S. airspace. Since the crash of Ethiopian Airlines 302, more than 300 Boeing 737 Max passenger jets have been grounded worldwide. In October, Lion Air Flight 610 crashed in Indonesia, killing 189 people. ... Boeing 737 Max crash victim … Pour la deuxième fois dimanche, un Boeing 737 MAX 8 s'est écrasé quelques minutes après … As a result, additional flight deck effects (such as IAS DISAGREE and ALT DISAGREE alerts and stick shaker activation) resulting from the same underlying failure (for example, erroneous AOA) were not simulated and were not in the stabilizer trim safety assessment report reviewed by the NTSB. Boeing has suffered directly through increased costs, loss of sales and revenue, loss of reputation, victims litigation, client compensation, decreased credit rating and lowered stock value. Boeing will stop charging extra for one of the safety features, a source tells the Times: the disagree light that was missing from both crashed jets, which would have activated if the angle of attack sensors were at odds with each other. A series of failures led to the crash of a Lion Air flight, which killed 189 people and led to the grounding of the Boeing 737 Max, a report has found. The Max 7 and 10 models, not yet delivered, are due for roll-out in the next few years. The Department of Justice says Boeing defrauded the United States by lying to the Federal Aviation Administration before and after two fatal 737 Max crashes in 2018 and 2019. On Sunday, March 17th, Muilenburg issued a statement describing steps the company was taking to update its technology. [2] The FAA revoked Boeing's authority to issue airworthiness certificates for individual MAX airplanes and imposed a fine on Boeing for exerting "undue pressure" on its designated aircraft inspectors. The design of the 737 Max series is based on the Boeing 737, an aircraft series that has been in service since 1968. [62], On March 17, 2019, Dagmawit Moges, Ethiopia's transport minister, announced that the black box had been found and downloaded, and that the preliminary data retrieved from the flight data recorder show a "clear similarity" with those of Lion Air Flight 610 which crashed off Indonesia. Airbus downplayed that it is "winning" in any way due to the MAX grounding, citing its own logistical and supplier capacity to fulfill orders for the A320 family aircraft. In December 2018, a month after the Lion Air accident, the FAA had conducted an internal safety risk analysis predicted fifteen more crashes with no repairs to MCAS, but that report was not revealed until the U.S. House hearing in December 2019. ", "Blaming Dead Pilots Brought to You by Boeing", "FAA To Take Full Control of Max Airworthiness Certification", "Boeing Statement on 737 MAX Simulator Training", "FAA completes three days of 737 Max flight testing", "After 18-Month Investigation, Chairs DeFazio and Larsen Release Final Committee Report on Boeing 737 MAX", "FAA's Dickson flies Max, declares 'I like what I saw, "Report: Europe closing in on decision to let 737 Max fly", "Boeing's 737 Max Will Be Flying Again. Boeing expressed its sympathy to the relatives of the Lion Air Flight 610 and Ethiopian Airlines Flight 302 crash victims, while simultaneously defending the aircraft against any faults until rebutted by evidence. [85] In September 2020, the House of Representatives concluded its investigation and cited numerous instances where Boeing dismissed employee concerns with MCAS, prioritized deadline and budget constraints over safety, and where it lacked transparency in disclosing essential information to the FAA. The 737 Max crashes in Indonesia and Ethiopia killed 346 people within five months in 2018 and 2019. Boeing says the decision to include this change to the flight control operations wasn’t arbitrary. First deployed on the Boeing KC-46 Air Force tanker, the MCAS software flight control law adjusts the horizontal stabilizer to push the nose down when the aircraft is operating in manual flight with flaps up at an elevated angle of attack (AoA). March 20, EASA and Transport Canada indicated that they would conduct their own reviews of Boeing's proposed software update. We have yet to hear any information from Ethiopian Airlines 302’s black box beyond initial (and vague) reports about similarities to Lion Air 610. The first Boeing 737 Max crash was 2 years ago today. The Indonesian rescue team located the flight data recorder on November 1st.

But other features involve communication, navigation or safety systems, and are more fundamental to the plane’s operations. "There was a directive by Boeing, so they took that training. The Chicago-based company has stopped delivery of all new Max jets to its customers. [4] The 20-month grounding, the longest ever for a U.S. airliner, weighed on Boeing at an estimated direct cost of US$20 billion and indirect costs of over US$60 billion. Mica Endsley of the Human Factors and Ergonomics Society testified that "The cues received by the pilots [...] were significantly different than the cues received with a runaway stabilizer trim". Last month, the U.S. Federal Aviation Administration cleared the jet following design changes around systems involved in two crashes that together killed 346 people … Up Next. “While investigators continue to work to establish definitive conclusions, Boeing is finalizing its development of a previously-announced software update and pilot training revision that will address the MCAS flight control law’s behavior in response to erroneous sensor inputs,” Muilenburg said. And The New York Times has a video that explains how MCAS is supposed to work. Accident reports by both the Indonesian NTSC and the Ethiopian ECAA determined the crashes were caused by faulty aircraft design and other factors, including maintenance and flight crew actions. [63][64] Due to this finding, some experts in Indonesia suggested that the NTSC should cooperate with Flight 302's investigation team. [70] The FAA issued an emergency airworthiness directive, 2018-23-51, on November 7, 2018 requiring the bulletin's inclusion in the flight manuals, and that pilots immediately review the new information provided. [86], In November 2020, the FAA announced that it had cleared the aircraft to return to service,[3] subject to the implementation of various design, operation, maintenance and training changes. [54][55][56], Ethiopian Airlines spokesman Biniyam Demssie said that the procedures for disabling MCAS had just been incorporated into pilot training. Under pressure to approve its new Max jets so it could catch up to Airbus, Boeing turned in a safety assessment to the FAA that was riddled with errors, the Times reported. The bulletin describes warnings triggered by erroneous AoA data, and referred pilots to a "non-normal runaway trim" procedure as resolution, specifying a narrow window of a few seconds before the system would reactivate and pitch the nose down again. The MAX was exempted from certain newer safety requirements, saving Boeing billions of dollars in development costs.[82]. On October 11, 2019, David L. Calhoun replaced Dennis Muilenburg as chairman of Boeing, then succeeded Muilenburg's role as chief executive officer in January 2020. ", "Boeing Statement on Lion Air Flight 610 Preliminary Report", "Ethiopian Airlines crash is the second disaster involving Boeing 737 MAX 8 in months", "Indonesia to Fault 737 MAX Design, U.S. The aircraft maintenance records indicated that the AoA Sensor was just replaced before the accident flight.
