Incident Overview
A supply mission to an Antarctic expedition between the Mirny and Vostok stations ended in a crash landing when the aircraft's right engine failed. The crew attempted an emergency landing, but the aircraft came down on a glacier located 560 kilometers from Mirny Ice Station. All four occupants were successfully rescued. The aircraft sustained damage beyond repair.
Engine Failure
The flight was progressing normally until the right engine malfunctioned. The crew responded by initiating emergency procedures and attempting to land the aircraft. The loss of engine power forced the aircraft down onto the glacial terrain.
Rescue and Damage
Following the crash, rescue operations were conducted. All four individuals on board were extracted safely. The aircraft, however, was destroyed and deemed not recoverable.
Investigation Findings
The official investigation determined the probable cause of the accident to be a failure of the right engine due to a loss of hydraulic pressure.
