Type of aircraft:
Landing (descent or approach)
Moscow – Leninakan
Crew on board:
Pax on board:
The aircraft was on its way to Leninakan to drop soldiers, first aid, medics and goods for the victims of the recent earthquake. On final approach by night, the aircraft disappeared from the radar screens after it stroke the slope of a mountain located 15 km from the runway threshold. All 9 crew members and 68 of the 69 passengers were killed. A survivor was found among the debris (he was seating on the deck of a truck parked in the cargo compartment) but unfortunately died a day later.
The accident was caused by an error on part of the crew who set a wrong altimeter pressure prior starting the descent to Leninakan (734 mm instead of 634 mm). This caused the aircraft to start the descent prematurely, dropping below the glide path and striking the mountain.
