Accident Details
A flight from Dikson landed at Norilsk-Alykel Airport at a speed of 200 km/h. Following touchdown, the crew initiated the braking procedure. The captain inadvertently raised the landing gear, but because the gear were locked down, they remained extended.
After the aircraft entered the taxiway, the crew increased power. As the speed reached 135 km/h, an unloading of the landing gear and a decompression of the right hand main landing gear damper occurred. This caused the right main gear to collapse slowly.
The airplane went out of control, veered to the right, and came to rest off the taxiway. All 20 occupants escaped uninjured. The aircraft was damaged beyond repair.
Probable Cause
The official investigation attributed the accident to failure of the crew who mistakenly raised the landing gear during the deceleration procedure and an excessive speed while taxiing.
