German investigators: misplaced downlock (locking) pin in Lufthansa Boeing 787-9 preceded Frankfurt nose-gear collapse
German aviation investigators said the nose-gear collapse of a Lufthansa Boeing 787-9 at Frankfurt last month involved a misplaced locking pin. The pin was found still in its storage box after the event, and investigators reported maintenance/gear-door troubleshooting was underway before the dramatic collapse that injured 23 people.
