The Wall Street Journal reported that Boeing identified a previously undisclosed 737 MAX software glitch that can disable an automated navigation feature during landing. The company acknowledged the problem to the Journal, which said it emerged after a cockpit software update.
When it can happen
According to the Journal, the issue can arise if pilots change their planned path after a missed approach. In that scenario, crews may have to fly by hand without some autopilot functions, industry officials told the Journal. Those officials said that could overload crews at low altitude, possibly in bad weather.
Boeing’s position and timeline
Boeing told 737 MAX operators in late August that the issue did not pose a safety risk, according to a company document reviewed by the Journal. “We shared information with operators that reinforced existing pilot procedures for safely handling such cases,” Boeing said. “Our engineers are working on a software update to permanently address the issue.”
Per the Journal, Boeing said in its August fleet notice that it expected more guidance by November and a permanent software fix in early 2028. The manufacturer also said it is working with airlines on a procedure to restore the automated navigation feature if needed.
FAA involvement
After further talks with airlines, Boeing began a formal safety review this month and shared the results with the Federal Aviation Administration, the Journal reported. The paper added that an FAA inquiry could affect approval of a new 737 MAX variant.
Airline pushback
Southwest Airlines and United Airlines have told Boeing they do not want new 737 MAX jets with the updated software and have asked for an earlier version instead, industry officials told the Journal.
