Boeing has disclosed a software issue in 737 MAX flight computers that may limit automated navigation during certain landing scenarios.

Boeing has identified a previously undisclosed software glitch in its 737 MAX aircraft that could cause an automated navigation feature to fail during landing. The issue, which stems from a cockpit software update, may occur if flight crews change their planned flight path following a missed approach. Boeing stated it informed all 737 operators of the situation in August.

Operational Impact and Response

The software glitch may prevent pilots from accessing automated flight guidance during specific landing scenarios. In response, Boeing has provided operators with information reinforcing existing pilot procedures for safely managing such cases. The company confirmed that its engineers are currently developing a software update to provide a permanent resolution to the issue. Major carriers, including Southwest Airlines and United Airlines, have reportedly requested that Boeing refrain from delivering new 737 MAX aircraft equipped with the affected software. Instead, these airlines have asked to receive planes featuring an earlier version of the software.

Regulatory Oversight

The Federal Aviation Administration (FAA) confirmed it is aware of the potential issue regarding the flight computer software on certain 737 MAX models. The agency is working in coordination with Boeing and the airlines to assess the situation. To determine if the glitch poses a significant flight-safety concern, the FAA plans to convene a Corrective Action Review Board. The agency stated it will take immediate action if it identifies a safety risk. At this time, it remains unclear how many aircraft currently in operation are equipped with the affected software.
