Boeing Flags New 737 MAX Software Glitch That Could Disable Landing Navigation
By Drooid · · How we work
New Glitch Identified
On September 26, Boeing disclosed a previously undisclosed software defect in the 737 MAX flight-control computers. The flaw can disable an automated navigation function during a landing after a missed approach when pilots alter their flight path. In such cases, crews may need to fly manually at low altitude without certain autopilot aids.
Background and Context
The issue emerged after a cockpit software update and follows years of heightened scrutiny of the 737 MAX program, which suffered two fatal crashes in 2018-2019 and a recent cabin-panel blowout on an Alaska Airlines MAX 9. Boeing’s internal review traced the defect to code changes made in November 2024, though the company initially judged it did not meet criteria for a formal safety review.
Official Statements & Responses
Boeing said it informed all operators in late August and reiterated that existing pilot procedures remain safe. The Federal Aviation Administration confirmed awareness of the potential problem, announced it will convene a Corrective Action Review Board, and pledged to act promptly if a safety concern is identified. Boeing added that engineers are developing a permanent software fix, now targeted for early 2028.
Data & Statistics
- The glitch affects the automated landing-navigation feature only after a missed approach and flight-path change.
- Southwest Airlines and United Airlines have requested that Boeing deliver new aircraft with an earlier software version rather than the affected code.
- The number of 737 MAX jets currently operating with the flawed software has not been disclosed.
- Boeing’s planned software update, originally slated for early 2028, is being accelerated to address the issue.
