FAA finds Boeing 737 MAX software bug 'not a safety concern'

The Federal Aviation Administration (FAA) concluded on Friday that a software bug discovered in Boeing's 737 MAX 10 aircraft does not constitute a safety concern, following an extensive investigation. The glitch, found in the cockpit software update, had the potential to render an automated navigation feature ineffective when the plane adjusted its approach to landing.

This determination was made by a panel of FAA safety experts who affirmed that pilots maintain full control of the aircraft, and indications to the flight crew are transparent and unambiguous.

The FAA's review board concluded that the software bug does not pose a safety concern because pilots retain complete control of the aircraft and the indications to the flight crew are clear and unambiguous. The FAA stated that it would consider appropriate action if new information about the issue arises. Boeing will subsequently distribute a bulletin to airlines, detailing the issue and instructing employees on how to recognize and respond to the situation should it occur.

Boeing affirmed that it had informed all 737 operators about the software issue, wherein pilots might not have access to automated flight guidance during a specific landing scenario. The company is actively working on a formal procedure with airlines that would enable pilots to restore automated flight guidance if the glitch occurs. Despite the FAA's review, the regulator and Boeing have not disclosed if the certification process for the 737 MAX 10 would be unfrozen.

The 737 MAX 10 is the final of four 737 MAX models to receive regulatory certification for service. FAA Administrator Bryan Bedford stated at a press conference on Monday that the MAX planes already certified by the FAA are safe, but the agency will delay the certification of the 737 MAX 10 until the safety issue is addressed.
