A Boeing 787-9 Dreamliner's nose landing gear failed while parked at a gate at Frankfurt Airport on June 4, 2026 [4].

The incident injured ground personnel and forced the cancellation of a scheduled flight. This failure occurred while the aircraft was stationary, raising questions about the mechanical integrity of the landing gear system.

Several Lufthansa employees were injured when the gear collapsed or unexpectedly retracted [3, 5]. The exact nature of the failure is currently under investigation, as reports differ on whether the gear collapsed or retracted into the fuselage [3, 5]. The aircraft involved is reported to be one year old [1, 6].

Lufthansa cancelled flight LH450 following the incident [1]. The aircraft remained at the gate in Frankfurt, Germany, where it was attended to by airport staff and technical teams [3, 4].

Boeing said it is aware of the situation and is supporting Lufthansa during the investigation [4, 5]. The company has not yet released a specific cause for why the gear failed while the plane was not in motion.

Investigators are now working to determine if the failure was caused by a maintenance error, a manufacturing defect, or a systemic mechanical fault. Because the aircraft was relatively new, the focus of the probe may include the quality of the components used in the 787-9's landing gear assembly [1, 6].

Several Lufthansa employees were injured when the gear collapsed or unexpectedly retracted.

A landing gear failure on a stationary, nearly new aircraft is a rare event that suggests a potential critical failure in the locking mechanisms or hydraulic systems. If the investigation reveals a manufacturing defect, it could lead to mandatory inspections or fleet-wide bulletins for other Boeing 787-9 Dreamliners to ensure the safety of ground crews and passengers.
