Boeing has identified a software glitch in its 737 MAX aircraft that could cause an automated navigation feature to fail during landing, according to a report by The Wall Street Journal. The planemaker informed 737 MAX operators in late August that the issue does not pose a safety risk, the report added. Reuters could not immediately verify the report.
A separate Boeing 737 MAX safety bulletin issued in July 2026 prompted a software update rollout across the fleet to enhance operational stability by refining control-law logic to prevent anomalous behaviors in rare flight regimes. This update continues iterative safety enhancements that began with post-grounding modifications to the Maneuvering Characteristics Augmentation System (MCAS). CFM International also updated LEAP-1B engine control software to mitigate cabin smoke risks following bird strikes.
