[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. [64] On March 13, 2019, the FAA announced that evidence from the crash site and satellite data on Flight 302 suggested that it might have suffered from the same problem as Lion Air Flight 610 in that the jackscrew controlling the pitch of the horizontal stabilizer of the crashed Flight 302, was found to be set in the full "nose down" position, similar to Lion Air Flight 610. On November 6, 2018, four days before it identified MCAS by name, Boeing published a supplementary service bulletin prompted by the first crash. Boeing's 737 Max, flown by airlines around the world, was grounded for nearly two years after crashes in Indonesia and Ethiopia raised questions about their safety. 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). Entering 2020, Southwest Airlines was desperate to get the Boeing 737 MAX back in its fleet as soon as possible. [104][105] Boeing admitted that the MCAS played a role in both accidents and asserted that MCAS is not an anti-stall system. "All the pilots flying the MAX received the training after the Indonesia crash," he said. 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. Inspector General's report revealed that MCAS problems dated several years before the accidents. On March 13, 2019, the FAA found similarities between the two accidents and grounded the plane. By then, most other regulators had already grounded the aircraft. When Boeing induced a stabilizer trim input that simulated the stabilizer moving consistent with the MCAS function, "... the specific failure modes that could lead to unintended MCAS activation (such as an erroneous high AOA input to the MCAS) were not simulated as part of these functional hazard assessment validation tests. At the time of the recertification by the FAA in November 2020, Boeing's net orders for the 737 MAX were down by more than 1,000 aircraft,[5] 448 orders canceled and 782 orders removed from the backlog because they are no longer certain enough to rely on; the total estimated direct costs of the MAX groundings were US$20 billion and indirect costs over US$60 billion. Preliminary investigations revealed serious flight control problems that traumatized passengers and crew on the aircraft's previous flight, as well as signs of angle-of-attack (AoA) sensor and other instrument failures on that and previous flights, tied to a design flaw involving the Maneuvering Characteristics Augmentation System (MCAS) of the 737 MAX series. [97], In November 2020, the FAA announced that it had cleared the aircraft type to return to service. [89] The NTSB expressed concerns that the process used to evaluate the original design needs improvement because that process is still in use to certify current and future aircraft and system designs. Chesley Sullenberger commented upon the "cozy relationship" that exists between the industry and its regulators. By March 18, all 387 aircraft were banned from service. The message, MOM-MOM-18-0655-01B, is included in the Lion Air Accident Report. "There was a directive by Boeing, so they took that training.

September 30, a Boeing 737 MAX test aircraft was flown by FAA administrator. 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. June 26, flight tests for the FAA uncovered a data processing issue affecting the pilots' ability to perform the "runaway stabiliser" procedure to respond to MCAS errors. January 7, Boeing recommended "simulator training in addition to computer based training". Most airlines seek compensation from Boeing to cover costs of the disruption, while the 737 MAX received some support when International Airlines Group (IAG) announced at the June 2019 Paris Air Show it could order 200 jets. [72] The French aviation accident investigation agency BEA announced that it would analyze the flight recorders from the flight. During the certification of the MAX in 2017, Boeing removed a description of MCAS from the flight manuals, leaving pilots unaware of the system when the airplane entered service. In February 2020, the DOJ investigated Boeing's hiding of information from the FAA, based on the content of internal emails. Following intense pressure from pilot unions and customers, Boeing finally revealed the name MCAS in a message to operators. A recent congressional report faulted both … In December 2018, the FAA privately predicted that MCAS could cause 15 crashes over 30 years, but expected Boeing to fix MCAS by April 2019. The Maneuvering Characteristics Augmentation System (MCAS) is an automated flight control developed by Boeing which became notorious for its role in the two fatal accidents of the 737 MAX, killing 346 passengers and crew on board before the aircraft was grounded worldwide in 2019. [111] Its extensive supply chain providing aircraft components and flight simulators suffered similar losses, as did the aircraft services industry, including crew training, the aftermarket and the aviation insurance industry. December 17, Boeing confirmed the suspension of 737 MAX production from January 2020.

Indonesia, for Lion Air Flight 610 as state of registration, state of occurrence and state of operator. Not one is contributing more than the other. The MAX was given the same type certificate as previous 737 generations to reduce pilot training and save money for its airline customers, a major selling point. [92] The FAA's Organization Designation Authorization program, allowing manufacturers to act on its behalf, was also questioned for weakening its oversight of Boeing. [66][67][68], Ethiopian Airlines spokesman Biniyam Demssie said that the procedures for disabling MCAS had just been incorporated into pilot training. In 2020, an FAA Airworthiness Directive[106] approved design changes for each MAX aircraft, requiring input from two AoA sensors for MCAS activation, elimination of the system's ability to repeatedly activate, and allowing pilots to override the system if necessary. The FAA resisted grounding the aircraft until March 13, when it received evidence of accident similarities. – House report", House Committee on Transportation and Infrastructure, Continued Airworthiness Notification to the International Community, Reactions to the Boeing 737 MAX groundings, Financial impact of the Boeing 737 MAX groundings, "Boeing's 737 Max debacle could be the most expensive corporate blunder ever", "U.S. lawmakers question Boeing's $1 mln rebate clause for Southwest 737 MAX orders", "Boeing 737 MAX can return to the skies, FAA says", "FAA clears Boeing 737 Max to fly again 20 months after grounding over deadly crashes", Final Committee Report on the Design, Development, and Certification of the Boeing 737 MAX, "Flight control feature of Boeing 737 MAX under scrutiny after Lion Air accident", "The Boeing 737 MAX: examining the design, development, and marketing of the aircraft", "Boeing Statement on Operations Manual Bulletin", "Boeing nearing 737 Max fleet bulletin on AoA warning after Lion Air crash", "Final Committee Report on the Design, Development, and Certification of the Boeing 737 MAX", The House Committee on Transportation and Infrastructure, "The many human errors that brought down the Boeing 737 Max", "Emergency Airworthiness Directive (AD) 2018-23-51", "In Indonesia Plane Crash Inquiry, New Focus on Possible Aircraft Problems", "Crash: Lion B38M near Jakarta on Oct 29th 2018, aircraft lost height and crashed into Java Sea, wrong AoA data", "Boeing 737 MAX crisis: a timeline (Part I)", "Timeline of the twists and turns in the grounding of the Boeing 737 Max", "Pilot Union President to Call for Accountability from Boeing and Reassessment of FAA Certification Process", "FAA 2018 analysis warned of 15 fatal Max crashes months before second accident", "After Lion Air crash, Boeing doubled down on faulty 737 MAX assumptions", Summary of the FAA's review of the Boeing 737 MAX, "European, Canadian regulators to do own review of Boeing jet", "How much was pilot error a factor in the Boeing 737 MAX crashes?
