Boeing's 737 Max 10 Certification Delayed Again
Boeing's attempt to certify its largest 737 Max jet has hit another obstacle. The Federal Aviation Administration (FAA) confirmed on September 28, 2026, that certification of the 737 Max 10 has been delayed due to a software issue identified during testing.
The setback extends an approval process that has already stretched on for years. Boeing had hoped to secure clearance for the Max 10 this year, but the newly discovered software problem now pushes that timeline further out.
The FAA said the issue involves software tied to the aircraft's flight control systems, which was flagged by regulators during recent evaluations and must be addressed before certification can move forward.
Airlines with orders for the Max 10, including WestJet, United Airlines, and Delta Air Lines, are watching the situation closely. The delay could force some of these airlines to adjust their fleet plans, particularly those counting on the larger jet to replace aging aircraft or expand capacity on high-demand routes.
