Regulatory Scrutiny Amid 737-10 Certification And Delivery Delays

The Federal Aviation Administration (FAA) is reviewing a software flaw in the Boeing 737 MAX’s flight management computer (FMC) that affects versions 14 and 14.1. The issue, which can cause the flight guidance system to drop out of vertical navigation during precision approaches, has led Southwest and United Airlines to reject new jets with the affected software. Boeing has described the glitch as not urgent and is working on a permanent software update, expected in 2028. The FAA review comes as Boeing works to secure certification for the 737-10, with the manufacturer facing potential delays in delivery schedules. This development was first reported by The Aviation Hub.
