Narrative:
An Antonov 2R sustained substantial damage in a forced landing in a wooded area, 60 km from Bratsk, Irkutsk Region, Russia following a loss of engine power. One crew member was injured.

Probable Cause:

The crash of An-2 RA-35141 aircraft occurred during the emergency landing on a forest firebreak. The landing was forced by the in-flight engine power loss as a result of the destruction of the 62.06.02 bronze hub pouring of the master rod big end of the crank mechanism.
Most probably the destruction of the bronze hub pouring was caused by a manufacturing flaw consisting in a lack of bronze friction with the steel base on a part of its surface.
