Airbus planes must now get their landing gear doors inspected, or risk being grounded

The US aviation regulator is ordering inspections of landing gear doors on many Airbus planes. This means airlines must check for jamming or inability to open the doors, and fix any problems, or the planes cannot fly.

A small mechanical issue can ground an entire fleet if not addressed. This directive forces airlines to spend money on inspections and repairs for a specific part. It also means that any affected parts cannot be installed on these planes in the future.
