Boeing (BA) is facing an investigation that will determine if the company failed to ensure that its completed products conformed to their approved design and were in safe operating condition, the Federal Aviation Administration said Thursday.
The investigation follows the Jan. 5 incident where a door plug fell off from 737-9 Max Alaska Air passenger jet shortly after takeoff.
“Boeing’s manufacturing practices need to comply with the high safety standards they’re legally accountable to meet,” the FAA in an update.
The regulator has grounded the 737-9 Max planes and said the timeline for their return would be determined based on safety of the public.
