Narrative:The An-2 struck a mound of earth during takeoff from a temporary agricultural airstrip near Zaboyskiy, Krasnodar region, Russia. The right-hand main gear collapsed.
The pilot was planning to conduct an aerial application flight on a rice field. It appeared that the pilots licence of the captain had expired in 2010.
Probable Cause:
The accident with the An-2 RA-01430 aircraft occurred during takeoff from a landing strip with a non-uniform surface, which led to the aircraft yawing during the takeoff run. Correcting the directional sway, the PIC allowed a sharp operation of the brakes and wheels, which, in turn, led to an uncontrolled turn to the left, as a result of which the aircraft rolled out of the landing area and collided with a bunker.
The contributing factors were most likely:
- the PIC's interruptions in flight work and, as a consequence, the loss of flight skills in aircraft piloting;
- failure to comply with the operator's RPM requirements in terms of training flight personnel on the An-2 aircraft;
- lack of a tail wheel locking mechanism on the An-2 RA-01430 aircraft;
- takeoff using the rated engine power with the flaps extended to the 20° position, which does not correspond to the Airplane Flight Manual of the An-2 aircraft, when taking off from a site with a non-uniform surface (take off at the engine takeoff power with the flaps deflected by 30°).
