final report is published and in part states:
Synopsis
Upon landing on runway 07 at Ilulissat (BGJN) in gusting crosswind conditions above the aircraft and the operator limited maximum crosswind components, the left main landing gear collapsed.
The aircraft skidded off the left side of the runway in a nose right position and into the safety zone.
The aircraft continued an increasingly sideways skid in a nose right position, skidded down a steep snow-covered slope and impacted a rocky area approximately 10 meters below the runway elevation.
One passenger and one crew member suffered minor injuries.
The aircraft was destroyed.
The accident occurred in dark night and under visual meteorological conditions (VMC).
The investigation did not result in recommendations being made. However, the AIB addressed an area of safety concern to Transport Canada (TC).
Summary
Adverse crosswind conditions at BGJN led to flight crew target fixation, a flight crew divergence from the operator’s stabilized approach parameters and a mental blocking of an appropriate decision on going around.
The flight crew divergence from the operator’s stabilized approach parameters induced a non-stabilized approach, which in combination with power levers retarded below flight idle in flight resulted in an accelerated rate of descent leading to a hard landing, with side load on the left main landing gear at touchdown.
The left main landing gear structural fuse pin sheared as a result of lateral and vertical overload stress.
Cycling the power levers between ground and flight range prevented an appropriate deceleration of the aircraft and prolonged the landing roll.
The prolonged landing roll combined with the application of full left rudder and no decisive use of reverse thrust on the side with the unaffected main landing gear made it impossible for the flight crew to maintain directional control.
The lack of directional control resulted in the aircraft running off the side of the runway and the safety zone, respectively.
