YAK-52, RA-3585K, 28 April 2011
During a tailchase, the aircraft entered an inverted spin at approximately 1,800 ft agl, probably because of unintentional pro-spin positioning of the flying controls. Although the spin ceased after three turns, the aircraft impacted the surface of a lake during the ensuing dive. The investigation identified several factors relevant to the accident, including operation of the aircraft, the type of flight instruments fitted to it and the manner in which the activity was conducted.
