Boeing's 737 MAX Software Glitch Raises Pilot Workload Concerns

Boeing has identified a software glitch in its 737 MAX aircraft that can cause the automated flight navigation system to malfunction during failed landing attempts. The issue, discovered in November 2024 but not deemed significant at the time, has raised concerns about pilot workload and prompted a review by the Federal Aviation Administration (FAA). The glitch causes the vertical navigation system (VNAV) to disconnect after an aborted landing or go-around, requiring pilots to manually input controls.

Boeing informed all 737 MAX operators of the issue in August 2026, stating that autopilot would remain functional and the problem did not pose a safety risk. However, several airlines, including Southwest Airlines and United Airlines, have expressed concerns about using the new software and plan to stick with previous versions.

The FAA has delayed certification of the Boeing 737 MAX 10 until a full safety assessment is completed. In October 2026, the aviation authority convened a Corrective Action Review Board (CARB) to assess the safety concerns around the software glitch.
