A preliminary report by German authorities has revealed that the absence of a nose landing gear ground lock pin caused the nose section of a Lufthansa Boeing 787-9 to collapse. The incident, which occurred at Frankfurt Airport, left several workers with minor injuries and underscores the critical importance of ground safety procedures.
The Finding: A Critical Oversight on the Ramp
The Bundesstelle für Flugunfalluntersuchung (BFU), Germany’s Federal Bureau of Aircraft Accident Investigation, issued an interim report clarifying the immediate causes of the occurrence. According to investigators, the mandatory lock pin had not been inserted into the nose gear prior to its unexpected retraction.
Instead of being secured in place to prevent the mechanism from accidentally cycling, the safety device was discovered inside a storage box in the aircraft’s forward cargo hold.
