Boeing is addressing a software flaw in its 737 MAX aircraft that can disable an automated flight guidance feature during a specific landing scenario, requiring pilots to fly manually. Boeing informed airlines about the issue in August. The Federal Aviation Administration (FAA) is investigating whether it poses a safety risk.
Southwest Airlines and United Airlines have asked Boeing to halt 737 MAX deliveries until a software update is developed and installed, according to reports. The requests could delay certification of the new 737 MAX 10 and complicate the service entry of the recently approved MAX 7.
Boeing says the issue does not pose a safety risk and has reinforced existing pilot procedures. The FAA investigation and the airlines’ requests add uncertainty to Boeing’s most crucial aircraft program.
