Boeing 737 Max 10 certification stalled by new software glitch

Boeing shares tumbled more than 6% following the announcement, reflecting investor anxiety over the latest hurdle for the company's best-selling aircraft family. CEO Kelly Ortberg had previously signaled to shareholders that government approval was imminent, but the discovery of a flaw in the vertical navigation system has upended that timeline. The issue specifically arises during go-around procedures, where an aircraft must abort a landing and re-align for a second approach.

Bedford noted that while the FAA recently cleared the smaller Max 7, this latest complication emerged after Boeing attempted to address an earlier system bug. The manufacturer inadvertently introduced a new error during that process. While U.S. carriers report that current operational fleets remain unaffected by the glitch, the delay leaves the Max 10’s entry into service in limbo until the FAA completes its comprehensive safety assessment.
