Yakovlev Yak-40

During the takeoff roll at Osh Airport, the captain decided to abort for unknown reasons. Unable to stop within the remaining distance, the aircraft verran and came to rest in a ravine. All 36 occupants evacuated safely while the aircraft was damaged beyond repair.

For unknown reasons, the aircraft landed hard and bounced several times before landing firmly. On touchdown, the nose gear collapsed and the airplane slid for few dozen metres before coming to rest. All 21 occupants escaped uninjured while the aircraft was damaged beyond repair.

The three engine aircraft departed Tehran-Mehrabad Airport at 0645LT on a charter flight to Gorgan, carrying members of the parliament and government who were flying to Gorgan to inaugurate the new airport. En route, the crew was informed by ATC about the deterioration of the weather conditions at destination and was instructed to divert to Sari Airport. While descending to Sari in marginal weather conditions, the crew failed to realize his altitude was too low when the aircraft struck the slope of a mountain located about 20 km south of the airport. The aircraft disintegrated on impact and all 30 occupants were killed. Among the passengers were Rahman Dadman, Iranian Minister of Transport and two vice-ministers.

The initial STD was 0800LT but as the passengers were late, the departure was postponed. Apparently to avoid to miss the slot, the crew precipitated the departure. After liftoff, the undercarriage were retracted immediately. At a speed of 230 km/h, the aircraft climbed to a height of 15 metres then rolled to the left at an angle of 65° and crashed 1,200 metres from the departure point. The aircraft was destroyed by impact forces and there was no fire. All nine occupants were killed, among them the Russian journalist Artiom Borovik. At the time of the departure, there were snow falls at Moscow Airport.
