FAA investigates software glitch in some Boeing 737 Max jets that could cause issues during aborted landings
The FAA is investigating a software glitch in Boeing 737 Max jets that may cause the vertical navigation system to disengage during aborted landings. Boeing says it is working on a software update and that pilots are trained to handle such cases. The issue affects software versions 14 and 14.1, and some airlines have delayed deliveries of new aircraft. The FAA will review the issue and take action if necessary. Boeing's Max 10 certification and Max 7 deliveries may be delayed.
