Boeing Identifies 737 MAX Software Glitch That Could Disrupt Navigation System

Boeing has discovered a software flaw in its 737 MAX aircraft that could disable an automated navigation system during landing after a missed approach. This issue surfaced following a cockpit software update and may force pilots to manually operate the plane at low altitude, according to The Wall Street Journal. The glitch was reported after a missed approach, but Boeing initially deemed it non-threatening in August.

The company is currently developing a remedy and a process to restore the automated navigation function. Several airlines, including Southwest and United, are urging Boeing to postpone deliveries of new MAX aircraft with the problematic software and utilize a previous version instead. The Federal Aviation Administration is currently probing the matter and may act if required.

Boeing first identified the glitch in November 2024, but it was not deemed a safety concern at the time. After receiving feedback from airlines, a formal review commenced this month, with findings shared with the FAA. Boeing aims to finalize a permanent software correction earlier than the initially projected timeline of early 2028.

This issue could also impact the certification of the 737 MAX 10 and the forthcoming MAX 7 models. It remains uncertain how many aircraft are presently operating with the affected software.
