Boeing Faces Challenge from Southwest and United Over 737 MAX Software

Boeing is facing another challenge with its 737 MAX software after two major airlines asked to have an earlier version installed on their new planes. Southwest Airlines and United Airlines want Boeing to deliver their new 737 MAX jets with a previous software version due to a glitch involving an automated navigation function.

The issue arises when a flight crew abandons a landing and changes the aircraft's planned route, causing the automated navigation feature to malfunction. This could leave pilots without some autopilot functions until they restore the system or continue using manual procedures, adding to their workload during a critical phase of flight.

Boeing identified the problem in August and informed 737 MAX operators, stating it didn't consider the issue a safety risk at the time. However, the company has since started a formal safety review and shared the results with the Federal Aviation Administration (FAA).

The FAA is investigating the matter and may act if necessary, according to a senior agency official. Boeing is working on a software update intended to permanently resolve the problem and has reminded operators of existing procedures pilots can use to handle such situations safely.
