FAA Clears Boeing 737 MAX Software Glitch as Safety Risk

The Federal Aviation Administration (FAA) determined on October 2, 2026, that a software glitch affecting certain Boeing 737 MAX aircraft does not pose a flight-safety risk. The issue, which affects software versions 14 and 14.1, can cause the automated vertical navigation (VNAV) system to disengage during a missed approach if pilots alter their preprogrammed flight path. This failure forces pilots to fly manually at low altitudes, increasing crew workload during critical landing stages.

Following the discovery, the FAA initially delayed the certification of the 737 MAX 10, the largest variant of the family. FAA Administrator Bryan Bedford stated the agency needed to determine if the glitch constituted a safety-of-flight issue. During the review, some carriers, including Southwest Airlines and United Airlines, refused deliveries of aircraft equipped with the affected software. In India, Akasa Air and Air India Express operate a combined 96 potentially affected aircraft, though Akasa Air maintained its operations remained safe.

The FAA's Corrective Action Review Board concluded that pilots retain full control of the aircraft and that flight crew indications remain clear and unambiguous. This ruling removes a major regulatory obstacle for the MAX 10 certification. Boeing is now working with GE Aerospace to develop a permanent software update and is coordinating with airlines to formalize procedures for pilots to reenable automated navigation should the glitch occur.
