Circumstances:
The aircraft was completing a mail flight from Tomsk to Baturino, carrying 757 kg of mail, 120 kg of various goods, two pilot and a passenger in charge of the fret. Six minutes before the estimated time of arrival in Baturino, while cruising at an altitude of 200 meters, the engine failed. The crew elected to make an emergency landing when the airplane struck trees and crashed inverted in a wooded area located 13 km from Baturino. The captain was killed while both other occupants were injured.
Probable cause:
The exact cause of the engine failure could not be determined. However, it is believed it may be caused by an excessive accumulation of calamine on the intake valves.
