Boeing flags 737 MAX software glitch affecting landing navigation feature, WSJ reports
Boeing said pilots can use manual procedures while it works on a software update and the FAA reviews the proposed fix.
On Saturday, Boeing identified a 737 MAX software glitch potentially causing automated navigation failure during landing, though the manufacturer maintains the issue does not pose a safety risk.
Boeing flagged the glitch last month when pilots alter preprogrammed flight paths after missed approaches, following years of delays for the Max family after deadly crashes in 2018 and 2019 that killed 346 people.
Major U.S. airlines told CNBC they do not possess the updated software tied to the glitch, with Southwest Airlines confirming "none of our fleet is equipped with Version U.14."
The Federal Aviation Administration said Saturday it is assessing the problem and "will take immediate action if it identifies a safety concern," while Boeing engineers work on a permanent software update.
Questions remain about the Max 7 and Max 10 models, though Boeing CEO Kelly Ortberg told investors earlier this month he expected FAA certification of the Max 10 "very soon" with 2,430 MAX aircraft in service globally.
The aircraft builder has granted another problem with his breakdown machine 737 Max. Two airlines have asked not to supply any new machines with the affected software for the time being.
