The 250-page report came about after an 18-month investigation by the Transport and Infrastructure Committee. “Boeing failed to design and develop the MAX, and the FAA failed to oversee Boeing and certify the aircraft,” it concluded.
The 737 MAX was Boeing’s best-selling aircraft until two aircraft crashed in close succession in late 2018 and early 2019. This was due to problems with the operating system.
According to the committee, the accidents were not the result of a single mistake. “They were the horrific accumulation of a series of erroneous technical assumptions by Boeing engineers, a lack of transparency on the part of Boeing’s board, and grossly inadequate oversight by the FAA.”
Also in a preliminary report, published in March, the committee had already taken a hard look at Boeing and the FAA. She then spoke of a “fundamentally defective and unsafe” aircraft. The 737 MAX planes have been grounded worldwide a few days after the second crash. A total of 346 people were killed in the two accidents.
