Boeing Deals With Another 737 Max 10 Certification Delay
Complication from software change causes concern for airlines with new narrowbody on order
Boeing 737 Max 10 airliner
Boeing had appeared to be on the cusp of achieving FAA type certification for its newest 737 Max narrowbody airliner.

Boeing's latest commercial aircraft program delay is unwelcome news for the company less than two weeks after it said that FAA certification of the 737 Max 10, already several years behind schedule, was finally at hand. Chief executive Kelly Ortberg said on September 16 that the longest and highest-capacity Max jet would be certified "very soon."

However, Boeing has since informed airlines flying 737 Max aircraft of a previously undisclosed glitch related to a cockpit software update, The Wall Street Journal reported on September 26. The issue prompted major U.S. airlines to request Max aircraft produced before the update was introduced by GE Aerospace in November 2024. Both Southwest Airlines and United Airlines have reportedly refused to take new jets.
