Boeing flags 737 MAX software glitch affecting landing navigation feature
BA•Boeing said it informed 737 operators about a software issue that could remove automated flight guidance in a specific landing scenario and is developing an update. The FAA is reviewing the issue, while Southwest and United asked Boeing not to deliver affected aircraft with the software.
1. Software issue and response
Boeing identified a software glitch that can affect an automated navigation feature during landing after crews change their planned flight path following a missed approach. Boeing said it informed all 737 operators last month and that its engineers are working on a permanent software update.
2. FAA and airline actions
The FAA said it was aware of a potential issue in a flight-computer software update on certain 737 MAX airplanes and was working with Boeing and airlines. It plans to convene a Corrective Action Review Board and said it would act immediately if it identifies a safety concern. Southwest and United asked Boeing to withhold new 737 MAX aircraft with the affected software and requested an earlier version.
3. Scope remains unclear
The number of aircraft operating with the software was not immediately clear. Boeing, airlines and regulators are assessing the issue and whether it poses a flight-safety concern.
