Boeing controversies

Boeing discloses 737 Max software glitch that could affect landing procedures

Hazard disclosure

In September 2026, Boeing disclosed that it had flagged a software glitch the previous month on some 737 Max aircraft. The issue could affect certain landing procedures, specifically within the vertical navigation system after a missed approach and go-around. It could cut off automated landing guidance, for example when there is an obstruction on the runway. Boeing stated that pilots are trained for those scenarios and remain in control of the aircraft. The FAA had not concluded whether the glitch is a safety-of-flight issue. The disclosure was reported as a controversy note concerning the 737 Max program.
