The Interstate Aviation Committee Investigation team has completed the investigation of the accident with Aeroprakt А-33-011 RA-0818G single-built private aircraft occurred in the Republic of Altai (RF) on 11.06.2016.

Most probably, the accident with the А-33-011 RA-0818G FVSP aircraft was caused by the aircraft stalling followed by spinning. 

Most probably, the contributing factors were:

- development of the pilot's fatigue and narrowing of his attention field caused by the long-range previous flight and the current flight operation (the flight duty period from the first takeoff till the accident was over 13 hours); 

- pilot's distraction from flight speed monitoring when maneuvering in the search area; 

- lack of sufficient training on using of the quick operating parachute rescue system QOPRS KC-700-O installed on the aircraft (the safety pin was placed on the throwing mechanism lock) allowing to rescue the crew as well as the aircraft in the case of in-flight emergency situation if it is not possible to perform the emergency landing.

Appropriate safety recommendations based on the investigation results were developed.
