FAA review reduces uncertainty over the Max 10 process
The U.S. Federal Aviation Administration (FAA) has concluded that a new software glitch found in some aircraft in the Boeing 737 Max family does not create a flight safety issue. The assessment, announced on Friday, kept the certification path open for the 737 Max 10, the latest model in Boeing’s best-selling aircraft family.
Boeing first raised the software issue last month. The FAA said on Monday that it was reviewing whether the glitch posed a safety risk. The agency’s panel of safety experts said pilots retained full control of the aircraft and that cockpit displays remained clearly understandable.
When does the software issue occur?
According to Boeing, the problem can occur when pilots change a preprogrammed flight route after a failed landing approach. In that case, pilots need to follow additional steps before they can use the automated systems on later approaches.
The FAA said it will issue a special bulletin to airlines explaining how to identify the issue and how to respond if it appears. The review board that met on Friday included specialists in structures, flight controls, propulsion systems and flight testing.
Why does the decision matter for Boeing and airlines?
The decision stands out as a development that could provide financial support for Boeing’s effort to sell and deliver more jets after years of safety and production crises. The Max 10 is the largest model in the 737 Max family and the final variant still awaiting government approval.
U.S. airlines said they were not directly affected in current operations because they can revert to older software versions. Even so, the software issue had raised questions about the Max 10 certification schedule, which had been expected in early autumn.
- The Max 10 is the largest aircraft in the 737 Max family.
- The Max 7, the smallest model in the family, received FAA approval in August.
- Alaska Airlines and Ryanair executives, among the Max 10 customers, said during the week that they saw only limited concerns about delays.
The FAA also said it would consider any additional steps if new information emerges on the issue. The approach suggests the regulator will continue to monitor the certification process closely without halting it altogether.
