Pilots flying Boeing aircraft in recent years have reported flight-control problems they blamed on malfunctioning software -- not on the company’s maligned 737 Max jets, but widely used earlier versions of the plane that are still in the air.
Commercial pilots flying Boeing’s NG, or “Next Generation,” models have registered concerns on a variety of computer problems through the Aviation Safety Reporting System, a database administered by NASA. In the past three years, pilots on different flights reported a range of issues, including losing airspeed on takeoff in some cases or the plane’s nose pitching downward without their command.
