Software Issue Affects Automated Vertical Navigation During Missed Approaches
Boeing is facing a new regulatory review of its 737 MAX aircraft family due to a flight management software issue that affects automated vertical navigation during a specific missed-approach scenario. The issue comes as the manufacturer approaches certification of the 737 MAX 10 and prepares for the commercial introduction of the 737 MAX 7. The U.S. Federal Aviation Administration (FAA) is working with Boeing and airlines to assess the issue, and the agency will convene a Corrective Action Review Board (CARB). Boeing has confirmed the issue and is developing a software update to address it permanently. The software problem was first reported by The Wall Street Journal on September 26, 2026, and this development was further reported by AeroTime.
