A plane crash-410UVP-E-Avia airline Saha in Aldan Airport

Date plane crash: 26.08.1993, the
Country of the crash: Russia
Location of the crash: Aldan Airport
aircraft Brand: L-410UVP
Registration of aircraft: RA67656
Name of air carrier: Saha air
Flight: 301

Chronology of events:

The take-off weight exceeded the allowable weight of 623 kg. The flight took place without deviations. At the time of the approach, the weight exceeded the maximum allowable landing for 550 kg, and the alignment was not less than 35,6 percent of the MAR, which exceeded significantly the rear (approximately 400 kg of baggage, in which the total weight of 687 kg was placed in the tail). The crew flaps released at 18 degrees, which required a slight rebalancing of the aircraft. The span of the BPRM was made on a low-gas mode, with a vertical speed of 4,8 m / s, at a speed of 200 km / h with a pitch angle of 6,6 degrees; At a height of 68,7 meters (at 31,3 meters lower than the established one). After 8 sec at a speed of 189 km / h, the crew on the low-gas mode started the flap release at 42 degrees; The plane began to intensively vibrate. The commander rejected the elevator from himself completely to the stop, holding it in this position for 20 seconds of flight. The flight speed was still intensively decreasing, and the pitching increased. The crew decided to go off to a second round, the engines switched to take-off mode and removed the flaps and chassis. But the angle of the pitch was still increasing, and the speed was falling. At a pitch angle of 42,5 degrees, at an air speed of 52 km / h the plane to the left wing fell off. The collision with the earth took place with a pitch pitch of 5,1 degrees; With the left bank 21 degrees; With a vertical speed of approximately 12 m / s at a distance of 273 m from the input threshold of the strip to the left of the axis of the strip 160 m. The aircraft collapsed completely.

The findings, which investigated plane crash

The plane crash occurred as a result of a collision between the aircraft and the ground in the process of reducing the aircraft with a large vertical speed after reaching the supercritical angles of attack and reducing the flight speed to values lower than the stall rates. Uncountable flight conditions, characterized by a sharp limitation of controllability in the longitudinal channel after the flap is released at 42 degrees; Were the consequence of gross violations by the crew of the requirements of the NPP GA-85 and RLE, which resulted in unreasonable decision-making for departure and flight of aircraft with a centering that exceeded the maximum permissible rear value and with a significant excess of take-off and landing masses.
