The FAA has assembled a new, multi-agency Technical Advisory Board (TAB) to review the proposed software fix for the Boeing 737 MAX’s maneuvering characteristics augmentation system (MCAS), the flight-control law implicated in two crashes of the aircraft type that killed 346 people over a five-month period.

New questions are being raised over the development and oversight of the Boeing 737 MAX after revelations the manufacturer knew about a misconfigured angle-of-attack (AOA) disagree annunciator alert message on the aircraft in 2017, but did not fix it or tell operators about the problem until after last October’s crash of a Lion Air 737 MAX 8—the first of two to strike the model in five months.

FAA is targeting late May or early June for approving Boeing’s proposed changes to the 737 MAX and issuing an airworthiness directive that would mandate the upgrades and clear the way for US MAX operations to resume, the agency told airline representatives April 12.
