Boeing 737 MAX faces new software issue

Boeing (BA) has identified a software glitch in the cockpit systems of certain 737 MAX aircraft that can cause an automated navigation feature to fail during landing. The issue arises particularly after a missed approach, when flight crews modify the planned flight path, and can disrupt the use of some autopilot functions in these scenarios.

The affected function is an automated navigation feature used during landing operations. In some conditions linked to this glitch, pilots may have to operate the aircraft manually without portions of the automated guidance that would normally be available.

Boeing informed 737 MAX operators in late August about the software issue and stated at that time that it did not consider the problem to pose a safety risk. Alongside the notification, the company shared information reinforcing existing pilot procedures intended to manage affected scenarios during landing.

Engineers are developing both a software update and a procedure designed to restore the automated navigation function when the glitch occurs. A permanent software fix had initially been expected in early 2028, and Boeing is now working to accelerate that schedule.

The Federal Aviation Administration is aware of the potential 737 MAX software issue and is reviewing the matter. The agency has indicated it will convene a Corrective Action Review Board as part of its assessment and has committed to taking immediate action if a flight-safety concern is identified during its review.

The FAA’s involvement focuses on evaluating the software behavior during missed-approach and landing phases and scrutinizing Boeing’s planned corrective measures. This regulatory process will influence how and when changes are implemented across the affected 737 MAX fleet.

Some carriers, including Southwest and United, have asked Boeing not to deliver new 737 MAX jets equipped with the affected software. These airlines have requested that upcoming aircraft be provided with earlier software versions instead of the version linked to the navigation glitch.

It is not yet clear how many 737 MAX aircraft are operating with the affected software. Boeing, airlines, and regulators are continuing to assess the scope of the issue while work progresses on software updates, operational procedures, and regulatory review.
