Boeing Develops Fix for 737 MAX Navigation Glitch

The Boeing Company identified a software glitch in certain 737 MAX aircraft that can cause automated navigation systems to fail during landing procedures. The failure occurs specifically after a missed approach when pilots alter a preprogrammed flight path. Boeing informed operators of the issue last month and is currently developing a software update to permanently resolve the problem.

The Federal Aviation Administration is assessing the glitch and will convene a Corrective Action Review Board to determine if immediate safety actions are required. Boeing is also working with airlines to formalize procedures that allow pilots to reenable automated vertical navigation if the situation occurs.

In response, Southwest Airlines and United Airlines stated they do not have aircraft equipped with the affected software, Version U.14, in their fleets. Both carriers have requested that new deliveries be equipped with an older software version to avoid the glitch. This development occurs as Boeing seeks federal certification for the MAX 10, following the certification of the MAX 7 in August.
