Boeing's 737 Max 10 Certification Delayed Again Over Software Issue

The certification of Boeing's largest 737 Max jet, the 737 Max 10, has been delayed due to a software issue identified during testing. The Federal Aviation Administration (FAA) confirmed on Sunday, September 28, 2026, that certification had been pushed back after regulators flagged a problem with the aircraft's flight control systems.

The setback is the latest in a series of delays for the Max 10, which was initially expected to be cleared for service this year. The FAA said it will not approve the aircraft until Boeing demonstrates that it meets all regulatory requirements, and safety remains its top priority.

Boeing acknowledged the delay and stated that it is working with the FAA to resolve the matter. However, the company has not provided a revised estimate for when certification is expected to be granted. Airlines such as WestJet, United Airlines, and Delta Air Lines are watching the situation closely, as they have orders for the Max 10 and may need to adjust their fleet plans.

The delay adds to Boeing's challenges, which include production issues, quality control concerns, and heightened regulatory oversight. The company has faced repeated delays in certifying its Max aircraft, including the smaller Max 7, which has been stuck in certification limbo since 2019.
