Incident Overview
While conducting a night approach to runway 22L at Copenhagen-Kastrup Airport, the aircraft experienced a failure of its right engine. In response, the flight crew feathered the right propeller. During the same approach, the nose gear failed to deploy. The crew attempted manual recycling of the landing gear system, but this action did not resolve the issue. The approach was continued with the nose gear retracted.
Engine Failure
The right engine failure occurred as the aircraft neared the airport. The crew feathered the propeller to reduce drag. Subsequent investigation revealed that the engine failure resulted from the failure of the turbine assembly retention guide vane.
Nose Gear Malfunction
The nose gear did not extend when commanded. Manual recycling, a procedure to manually cycle the gear, proved ineffective. The loss of hydraulic pressure, caused by the engine failure, prevented the nose gear from lowering. The crew decided to proceed with the landing using the available systems.
Landing and Aftermath
The aircraft landed on its nose, touched down on the runway, and rolled for several dozen meters before coming to rest on the main runway. Both pilots exited the aircraft without injury. The aircraft sustained damage that rendered it beyond economical repair.
Probable Cause
According to the official accident investigation, the probable cause was the failure of the right engine due to the failure of the turbine assembly retention guide vane. This engine failure led to a reduction in hydraulic pressure, which in turn prevented the nose gear from being lowered.
