Boeing uncovers software flaw that could disable landing guidance on 737 MAX
The glitch can affect automated vertical navigation systems following a missed approach, though regulators say the aircraft remains safe to fly.
Boeing has identified a software defect on certain 737 MAX aircraft that can interfere with automated vertical navigation functions after a missed approach, raising fresh concerns about the troubled jet family.
The company and aviation regulators are still assessing the extent of the problem and deciding whether further corrective action will be necessary. Authorities have stressed that the flaw does not render the aircraft unsafe for commercial operations while that review is under way.
The discovery adds to a difficult period for Boeing, which faced intense scrutiny earlier this year after a door plug detached from an Alaska Airlines 737 MAX 9 during flight in January 2024, prompting investigations by both the manufacturer and federal safety authorities.
Boeing has been working to rebuild confidence in the 737 MAX following years of reputational and regulatory challenges. The company has not yet indicated a timeline for delivering a fix to airlines currently operating the affected aircraft.
