Accident

edit

While flight V-652 was inbound to Zheleznogorsk-Ilimskiy after its flight from Irkutsk on 18 September 1981, a Mil Mi-8T helicopter was also heading for the same airport after having finished its training flight from Bratsk. The crew of flight V-652 initiated their descent to the airport and had to pass through clouds while searching for the runway. When the plane was about 11 km (6.9 miles) East of the airport and at an altitude of 1,300 ft (396 m), it collided with the helicopter who was also descending at 7.13am. Flight V-652 suffered immense damage to its left wing, fuselage and tail section, while the helicopter's main rotor and cockpit were destroyed with serious damage to its fuselage as well.[2] Both aircraft nosedived towards the ground following the collision, and crashed in a wooded hilly terrain 400 meters (1,300 feet) from one another. None of the 29 passengers and 4 crew aboard flight V-652 survived the crash, and all 7 crew on board the Mil Mi-8T helicopter also perished in the disaster.[3]

Aircraft

edit

The Yakovlev Yak-40 involved, CCCP-87455 (msn 9431236) was built in 1974 and was used by Aeroflot from 1974 until its destruction in 1981. The Mil Mi-8T involved, CCCP-22268 (msn 6918) was also in use by Aeroflot at the time of the accident.[1]

Aftermath

edit

The wreckage of both aircraft were completely destroyed in the accident and post-crash fire. An investigation of the accident concluded that the cause lay with the poor surveillance conducted by ATC. The lack of communication between the three parties allowed the Mil Mi-8T helicopter to cross into the approach path of flight V-652.[4]
