Circumstances:

While approaching Akhtubinsk Airport, the pilot-in-command initiated a go-around for unknown reasons. After passing over the airport, the crew was instructed by ATC to make a turn to the right before joining the downwind circuit. While cruising at a relative low altitude south of the airport, the aircraft was shot down by an air-air missile fired from a Soviet Air Force MiG-23. Out of control, the airplane crashed south of the airfield, killing all eight occupants.

Probable cause:

It was determined that the MiG-23 pilot was completing an exercise south of the Akhtubinsk Airport and was supposed to use an helicopter as target. ATC at Akhtubinsk Airport transmitted wrong instructions to the AN-26 crew, and asked the pilot to make a right turn to the south of the airport, causing the aircraft to fly in a military area. A lack of coordination between civil and military personnel was considered as contributing factor as well as the fact that both AN-26 and MiG-23 crews were using different frequencies.

Circumstances:

After completing a cargo flight from Tiksi to Borogon, the crew was returning to Tiksi on a ferry flight. There were no passengers and no cargo on board. After takeoff from Borogon, while climbing to a height of 8 meters at a speed of 120 km/h, the flaps retracted automatically from 30° to zero. The aircraft entered an uncontrolled descent, struck the snow covered ground and crashed 250 meters past the runway end. All three crew members escaped with minor injuries while the aircraft was damaged beyond repair.

Probable cause:

It was determined that the flaps retracted prematurely and accidentally following a short-circuit by the flaps button where electrical resistances were corroded by condensation.
