FAA Delays Boeing 737 MAX 10 Certification Over Software Glitch

The Federal Aviation Administration (FAA) has delayed certification of Boeing's 737 MAX 10 due to a software glitch in the flight management computer (FMC) of certain 737 MAX aircraft. The issue affects versions 14 and 14.1 of the FMC software, supplied by GE Aerospace, which can cause the vertical navigation mode to disconnect after a go-around if the crew modifies the programmed route.

FAA Administrator Bryan Bedford stated that the agency will delay certification until it is satisfied that there is no problem with the software. Boeing shares fell around 6.9% on Monday, their worst day in nearly a year and a half, due to fears that the MAX 10 will slip once again.

Airlines such as WestJet, United, Southwest, Alaska Airlines, American Airlines, GOL, Copa Airlines, and Aerolíneas Argentinas have orders for the MAX 10, but the delay affects fleet plans rather than immediate operations. Boeing is working on a permanent update to resolve the issue.
