Narrative:An Antonov 2R sustained substantial damage when it force landed in a forest in the Kezhemsk District, Krasnoyarsk Territory, Russia.
The aircraft was carrying out aerial surveillance in connection with fires in the Krasnoyarsk Territory when the engine failed.
Probable Cause:
The accident of the An-2 RA-40646 aircraft occurred at the time of the forced landing on the forest. Its necessity was caused by spontaneous shutdown of the engine in flight as a result of destruction of bronze pouring of the bushing of 62.06.02 crank head of the main connecting rod of the crank mechanism.
Most likely, the destruction of the bronze casting of the bushing is caused by a manufacturing defect, which consists in the lack of adhesion of bronze to the steel base on the part of its surface.
