Aeroflot Flight Sh-4 was a scheduled passenger flight from Frunze to Dushanbe, with a stopover at Leninabad. On September 3, 1970, the Yakovlev Yak-40 was involved in an aviation accident, when it collided into Mount Airy-Tash. The crash resulted in the deaths of the 21 occupants and was the first accident involving the Yak-40.
Aircraft
The Yak-40, registration CCCP-87690 (MSN 9910503 - Serial number 03-05), was manufactured at the Saratov Aviation Plant in March 1, 1969 and was transferred to the Ministry of Civil Aviation, which on March 12, sent the aircraft to the Dushanbe Aerial Detachment of the Tajik Civil Aviation Directorate. The aircraft had the maximum capacity of 24 passengers. At the time of the accident, the aircraft had accumulated 1020 flight hours and 1344 cycles.
Accident
Flight Sh-4, being operated by the Yak-40, was operating the first leg by the flight crew of the 186th detachment, consisting of commander (PIC) V. F. Sutormin, First officer G. V. Karpov and Flight engineer V. T. Shashkina. The aircraft had 18 passengers onboard the flight. The aircraft departed Frunze Airport at 20:24, reaching the assigned altitude of 5,700 m (18,700 ft).
The crew did not realize that the aircraft had deviated to the west from the flight route. The crew radioed to ATC that they had passed over the towns of Namangan and Kokand. At 21:21, Leninabad ATC cleared the crew to descend to 3,300 m (10,800 ft) and then 2,100 m (6,900 ft), although they did not know the exact position of the aircraft.
At 21:26, the flight, flying at 2100 meters at a speed of 500 km/h (310 mph), struck the side of Mount Airy-Tash (90 km from Leninabad) at an altitude of 2,300 meters (7,500 ft) and was destroyed on impact, killing the 21 occupants onboard.
Causes
The commission had determined the following for the cause of the accident:
- Violation of the crew of within NPP GA-66 and NSHS GA-62 by the use of ground and aircraft navigation for the specific flight path, which led to the collision with the mountains.
- Reduction of the altitude of the aircraft by using the IFR when flying in the mountainous terrain by the dispatchers of Kokand and Leninabad, despite the lack of radar to show the aircraft’s actual location, and the non-use of technical meanings to control the flight maneuvers.
The commission had also found the following contributing factors, leading to the accident:
“Terrible navigation training for the PIC and F/O, lack of experience with the IFR during flights with the Yak-40. Both pilots had recently been retaught to fly the Yak-40, by flying the Il-14 and An-2. It was noted during training that on flights using the IFR, the curtains of the aircraft weren’t used due to the absence of the aircraft that were used for training.”
