Boeing 737 MAX Software Flaw Triggers FAA Review and Stock Drop

Key points

• Boeing notified operators in August of a glitch that can force manual landings after a missed approach.
• The FAA is investigating the issue, with Boeing aiming for a permanent fix by early 2028.
• Southwest and United Airlines have requested older software versions for future deliveries.
• Boeing stock fell 3% as the news emerged, while GE Aerospace shares eased.
• The FAA recently certified the 737-7, raising questions about its software configuration.

Background

This issue follows a period of production ramp-up challenges for the 737 MAX, including wing manufacturing constraints at Boeing's Renton plant. The airline has a history of safety reviews following previous incidents, which previously led to a two-year grounding of the MAX fleet.

How outlets are covering it

The Wall Street Journal and MyNorthwest.com emphasize the safety implications and the FAA's active investigation. Aviation Week highlights the timing relative to the upcoming certification of the 737-10. Yahoo Finance focuses on the market reaction, noting a 3% decline in Boeing shares. While Boeing asserts the aircraft are safe to fly, industry officials note that airlines are proactively reverting to older software to mitigate risks.

Why it matters

The glitch affects a fleet of over 2,400 737 MAX 8 and 9 aircraft. It complicates Boeing's efforts to restore trust after past safety issues and may impact the rollout of newer models like the 737-7 and 737-10, which are expected to use the new software.

What to watch

Boeing is working with GE Aerospace on a software update, with a permanent fix targeted for early 2028. The FAA will determine if further regulatory action is necessary. Airlines are deciding whether to accept new deliveries with the flawed software or revert to previous versions.
