Boeing Stock Plummets Amid Software Bug and Production Woes

Boeing shares plummeted to around $185 on Monday after a software bug was identified in the 737 MAX flight management system.

The issue involves automated vertical navigation guidance during certain missed-approach landing maneuvers and can cause autopilot functions to disengage following specific flight-path changes.

Boeing has assured airlines that existing manual pilot procedures safely address the condition while engineers work on a permanent software update, but this disclosure has prompted a formal review by the U.S. Federal Aviation Administration.

The regulatory review may create additional uncertainty around certification milestones for the 737 MAX 7 and MAX 10, increasing investor concerns about Boeing's near-term execution.
