Circumstances:
The crew departed Moscow Airport at 0420LT on a night mail flight to Leningrad. Few minutes after takeoff, weather conditions deteriorated with low ceiling and intermittent snow falls. While cruising at a height of 100 metres, the airplane entered a right turn, descended to the ground and crashed 2 km from the Poverovo Station. The aircraft was totally destroyed and both crew members were killed.
Probable cause:
The accident resulted from a loss of control in flight followed by a ground impact with an engine running normally at impact.
The following contributing factors were identified:
- Poor preparation for a night flight in difficult flying conditions due to low ceiling and snow falls;
- The pilot was unfamiliar with the Moscow - Leningrad route;
- Poor flight planning;
- The airspeed indicator only worked intermittently;
- Weather conditions deteriorated significantly during the flight.
