FAA certification of the MAX was subsequently investigated by the U.S. Congress and multiple U.S. government agencies, including the Transportation Department, FBI, NTSB, Inspector General and special panels. Both crashed jets were Boeing 737 Max 8s, a variant of the best-selling aircraft in history. 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". [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 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. [94] In January 2021, Boeing settled to pay over $2.5 billion after being charged with fraud. FAA's administrator, Stephen Dickson, who assumed the position during the accident investigations, said in retrospect that "the result was not satisfactory". "All the pilots flying the MAX received the training after the Indonesia crash," he said. [101] Twelve days after the Lion Air accident, on November 10, 2018, Boeing publicly revealed MCAS in a message to airline operators, noting that the system operates "without pilot input. [65] This further implicated MCAS as contributory to the crash. January 18, Transport Canada authorized the MAX to resume flights in Canadian airspace. December 17, in a presentation to the FAA, Boeing deflected blame and continued to assert that appropriate crew action would save the aircraft. More: Boeing sold 1 … 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 Boeing 737 MAX groundings drew mixed reactions from multiple organizations. Why did the Bek Air plane crash and how safe are Kazakh airlines? In February 2020, the DOJ investigated Boeing's hiding of information from the FAA, based on the content of internal emails. Boeing slowed MAX production to 42 aircraft per month until in January 2020, when they halted until the airplane is reapproved by regulators. Lawmakers investigated Boeing's incentives to minimize training for the new aircraft. Boeing has admitted knowing about problems with the 737 Max before deadly crashes brought the aircraft's safety issues to light. Boeing 737 Max: When will the doomed jet fly again?

[73] BEA received the flight recorders on March 14, 2019. 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. Opinion polls suggested most passengers are reluctant to fly again aboard the 737 MAX when it will be reintroduced, while most should be comfortable boarding it again after some time passes to prove its safe operations. [96] 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. A recent congressional report faulted both … [4] The 20-month grounding was the longest ever for a U.S. airliner, costing Boeing an estimated US$20 billion in fines, compensation and legal fees, and indirect losses in the form of 1,200 cancelled orders valued at more than US$ 60 billion  [5][1] Passenger flights resumed on the MAX in the U.S. and Brazil in December, and Boeing began deliveries of some 400 aircraft in its backlog. | The Seattle Times", "How Boeing went from appealing for government aid to snubbing it", "Boeing refuses to play ball as Dutch MPs reopen 2009 crash involving 737", "How the Boeing 737 Max Disaster Looks to a Software Developer", "What went wrong inside Boeing's cockpit? 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. 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). Congressman Sam Graves of the House Transportation Committee had blamed the 737 MAX crashes on substandard-quality training of the Indonesian and Ethiopian pilots; stating that "pilots trained in the U.S. would have been successful" in handling the emergencies on both jets, at the House Aviation subcommittee hearing in Washington D.C.[109][110] [75][76] Due to this finding, some experts in Indonesia suggested that the NTSC should cooperate with Flight 302's investigation team. • Boeing’s woes aren’t limited to the Max. On November 6, 2018, four days before it identified MCAS by name, Boeing published a supplementary service bulletin prompted by the first crash. The participating state or national transportation safety bureaus are the NTSB for the US and the NTSC for Indonesia. It still proved popular from the beginning, with over 5,200 gross orders since its launch. In February 2020, the global coronavirus pandemic and the resulting travel bans created further uncertainty for Boeing. [60][61][62][63], The initial reports for Flight 302 found that the pilots struggled to control the airplane in a manner similar to the Lion Air flight 610 crash. 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. Inspector General's report revealed that MCAS problems dated several years before the accidents. 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. In both crashes, MCAS was activated by an erroneous indication from an AoA sensor on the exterior of the airplane. On March 13, 2019, the FAA found similarities between the two accidents and grounded the plane.

Boeing's 737 MAX, the jetliner grounded for 20 months after two international crashes that killed 346 passengers and crew, resumed commercial flights Dec. 29. Even though U.S. regulators have approved the plane to resume flying, a number of steps must be completed before it can carry passengers. 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. Chesley Sullenberger commented upon the "cozy relationship" that exists between the industry and its regulators. Engineering reviews uncovered other design problems, unrelated to MCAS, in the flight computers and cockpit displays. For each aircraft, the FAA will issue an airworthiness certificate, without delegation to Boeing, upon completion of an AoA sensor system test and a validation test flight. 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. [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. In November 2018, a week after the Lion Air accident, Boeing issued a bulletin supplementing the flight operations manual to warn that the MAX could pitch down automatically when a sensor fails and to explain how pilots should respond.

[98] Various system, maintenance and training requirements are stipulated, as well as design changes that must be implemented on each aircraft before the FAA issues an airworthiness certificate, without delegation to Boeing. It further found that the assumption that simulator training would not be necessary had "diminished safety, minimized the value of pilot training, and inhibited technical design improvements". For fleet commonality, MCAS was added so that the MAX would handle similar to earlier 737 versions. [51] About 30 MAX aircraft were flying in U.S. airspace at the time and were allowed to reach their destinations. [107] The FAA began requiring all MAX pilots to undergo MCAS-related training in flight simulators. 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. [71] Both flight recorders (voice and data) were recovered from the crash site on March 11, 2019.
