Boeing's 737 MAX Software Glitch Raises Concerns Over Automated Approach Functions

Boeing has identified a software glitch in some of its 737 MAX aircraft, which could affect automated approach functions. The issue was first flagged in November 2024, but Boeing did not warn airlines until last month. The Federal Aviation Administration (FAA) is currently assessing the problem and will provide guidance on any immediate action needed.

The glitch affects the software version U.14, which is used in some MAX 8 and MAX 9 aircraft. Pilots are trained to land without relying on automated systems, but the glitch could cause them to lose access to vertical navigation (VNAV) during a landing approach. Boeing is working with airlines to formalize procedures for handling this situation.

No US carriers are affected by the issue, but some international airlines, such as Southwest Airlines and United Airlines, are taking precautions. The FAA has established a Corrective Action Review Board to evaluate the issue and provide any required changes for upcoming models, including the MAX 7 and 10.
