WestJet first told Boeing about 737 MAX software glitch cleared by FAA, memo says

The Federal Aviation Administration (FAA) has declared a software glitch in some Boeing 737 MAX flight computers does not pose a safety issue, paving the way for approval of a larger variant, the MAX 10. This decision clears a significant hurdle for certification of the MAX 10, which has been delayed for years. The FAA's determination, made by a panel of experts in Seattle, is based on the fact that pilots maintain full control of the aircraft and clear, unambiguous indications are provided to the flight crew.

The glitch could have prevented pilots from accessing automated flight guidance during an unusual landing scenario, but the FAA has decided that this does not present a safety concern. The MAX 10 could potentially be certified as soon as later this month, according to aviation officials. The issue could also affect airlines that have ordered the MAX 10, such as Southwest Airlines, Alaska Airlines, and United Airlines.

Boeing stated it will continue to follow the FAA's lead and work on the next software update, while also collaborating with airlines to establish a procedure for pilots to re-enable automated vertical navigation if needed. The FAA will issue a bulletin to airlines on how to recognize and respond to the situation, and to foreign regulators to ensure they are aware of Boeing's bulletin.
