Circumstances:
In the early morning of August 6, two GVF PS-84 registered CCCP-L3480 and CCCP-L3432 departed Pakhomovo on a positioning flight to Moscow-Vnukovo. Due to the actual situation, the crew was unable to receive information about weather conditions at the destination airport and the person in charge at Pakhomovo Airport cleared both crew to takeoff without receiving any information about the weather conditions at destination. About 3 to 5 minutes separated both takeoffs. Upon arrival at Vnukovo Airport, the crew of CCCP-L3480 encountered foggy conditions, initiated a go around procedure and followed a circuit. As the second airplane was attempting to land, it collided with the first one that was attempting to land on the same runway but from the opposite direction. Both airplanes crash landed. CCCP-L3480 was repaired and returned to service while CCCP-L3432 was damaged beyond repair. The crew was injured.
Probable cause:
The collision was the consequence of the combination of the following factors:
- The person in charge at Pakhomovo Airport cleared both crew to takeoff without receiving any information about the weather conditions at destination,
- Both crew departed Pakhomovo without such information,
- Lack of discipline on part of both crew,
- Lack of visibility at destination airport due to foggy conditions,
- Lack of communications between both airports,
- Poor organization and supervision at Vnukovo Airport.

Circumstances:
The airplane departed Moscow-Vnukovo Airport on a cargo flight to Vyazma, carrying five crew members and a load of ammunition and tracts. After takeoff from Vnukovo Airport, while climbing to a height of 20-30 metres, the left engine lost power. The airplane rolled to the left, lost height, impacted a tree and crashed, bursting into flames. Four crew members were injured and the mechanic was killed.
Probable cause:
A loss of power on the left engine for reasons that could not be determined with certainty. However, the period of time between the engine startup and the takeoff procedure was five minutes only, which was insufficient to allow the engine to be sufficiently hot.

Circumstances:
After landing at Moscow-Vnukovo Airport, the crew was taxiing to the apron with two engines off. At a relative high speed, the pilot-in-command saw a starter ahead prohibiting further taxiing. So the pilot reduced the throttle and attempted to turn to the right when the right main gear collapsed. The airplane came to rest and was damaged beyond repair. There were no casualties.
Probable cause:
The direct cause of the accident is the lateral load on the undercarriage while taxiing in a curved trajectory and braking with an excessive speed. Contributing to the undercarriage and spar failure is the weakening of the wheel strength by faulty rivets and aging of the structural material.
