Investigation team of the Interstate Aviation Committee has  completed the investigation of the accident with An-2 RA-35141 aircraft operated by Yenisey Airlines Ltd that occurred in the Irkutsk Region on 16.09.2015.

The crash of An-2 RA-35141 aircraft occurred during the emergency landing on a forest firebreak. The landing was urged due to 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.

Appropriate safety recommendations based on the investigation results have been developed.
