Circumstances:
At liftoff from Kuberganya Airport, the single engine aircraft encountered difficulties to gain height. It stalled, struck the ground and crash landed in a snow covered field, coming to rest 171 meters past the runway end. All 15 occupants escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
It was determined that the crew failed to prepare the flight according to published procedures and failed to follow the pre-takeoff checklist. Investigations reported that the flaps were deployed at an inappropriate angle of 8° instead of the prescribed 30°. At liftoff, the copilot realized the mistake and reduced the engine power to abandon the takeoff procedure but the captain took over controls and decided to continue the takeoff. Thus, the poor crew coordination was considered as a contributing factor.

Circumstances:
The single engine airplane departed Srednekolympsk Airport at 1147LT on a schedule service to Orlovo, carrying 12 passengers and two pilots. Weather conditions were excellent with a visibility of 50 km. About 19 minutes into the flight, weather conditions deteriorated with fog and a visibility below 1,000 meters. Instead of returning to Srednekolympsk, the crew decided to continue and reduced his altitude in an attempt to establish a visual contact with the ground, without success. During 46 minutes, the crew circled in the area of Orlovo to locate the landing field without success and eventually decided to return to Srednekolympsk. On approach of Srednekolympsk Airport, the engine failed. The crew attempted an emergency landing when the aircraft crashed 4 km short of runway. All 14 occupants escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
It was determined that the engine failed due to fuel exhaustion. The crew failed to return to the departure airport when weather conditions worsened with a visibility below minimums and the fuel quantity was insufficient for all flight.

Circumstances:
The four engine aircraft was completing a cargo flight from Tiksi to Irkutsk with an intermediate stop in Batagay, carrying six crew members and a load of 15,5 tons of apples. The descent to Batagay Airport was initiated by night and marginal weather conditions. Thus, the visibility was limited and the crew was unable to establish a visual contact with the ground or the airport. For unknown reasons, the crew and especially the captain failed to follow the approach procedures and preferred to follow a schema dedicated for VFR approach only. This caused the aircraft to descent below the minimum prescribed altitude when the GPWS warning sounded in the cockpit. The captain disengaged the GPWS alarm system and decided to continue the descent when, at a speed of 355 km/h, the aircraft struck the slope of a mountain located 25 km from the Batagay Airport. In a right bank of 22°, the aircraft crashed and disintegrated in a snow covered ground. All six occupants were killed.
Probable cause:
Poor approach planning and wrong approach configuration on part of the crew who continued the descent below the minimum descent altitude. After the GPWS warning sounded, the captain deactivated the system and continued the approach without any visual contact with the ground or the airport. In such conditions, the crew should initiate a go-around procedure.

Circumstances:
Following an uneventful flight from Yerevan, the crew initiated the approach to Aleppo in moderate turbulences. On final, the aircraft was unstable and out of trim when it adopted an excessive rate of descent of 5,5 meters per second and struck the runway surface. On impact, the undercarriage were torn off. The aircraft slid on its belly, overran and came to rest, broken in two. At least 60 occupants were injured.
Probable cause:
Wrong approach configuration on part of the crew who continued a visual approach in moderate turbulences with an unstable aircraft. The crew manually set the aircraft out of trim, causing the center of gravity to be aft the permissible limit.

The crew elected to make an emergency landing when the left main gear collided with rocks on the bank of the Tompo River. Our of control, the aircraft cartwheeled and crashed. All five occupants were rescued, two of them were injured, including the copilot.
Probable cause:
The exact cause of the engine failure could not be determined with certainty. However, it is believed that the carburetor got frosted after the crew forgot to activate the engine anti-ice system. Analyzes of the engine showed marks on the forward part of the compressor blades, indicating splinters of ice resulting from icing conditions.

Controlled flight into terrain after the crew decided to fly in limited visibility conditions below the minimum prescribed altitude.
