Boeing identifies 737 MAX software glitch affecting landing navigation feature
Key Points:
- Boeing has discovered a previously undisclosed software glitch in the 737 MAX that may cause an automated navigation feature to fail during landing, specifically when pilots alter their flight path after a missed approach.
- The company informed all 737 operators last month and is developing a software update to permanently fix the issue, while reinforcing existing pilot procedures for safe handling.
- The FAA is aware of the problem, is collaborating with Boeing and airlines, and will convene a Corrective Action Review Board to address any safety concerns.
- Southwest Airlines and United Airlines have requested Boeing delay deliveries of new 737 MAX aircraft with the affected software, preferring an earlier software version instead.
- The number of aircraft currently operating with the flawed software is unclear, and Boeing, regulators, and airlines are evaluating the safety implications.
