Circumstances:
The single engine airplane departed Zhelenogorsk-Ilimsky Airport on a flight to Achinsk with an intermediate stop in Taseyovo, carrying one passenger and two pilots. After 43 minutes into the flight, while cruising at an altitude of about 1,200 metres, the engine lost power and the oil temperature increased from 70° to 150° C. The aircraft lost height, forcing the crew to attempt an emergency landing. The aircraft hit tree tops and eventually crash landed in a wooded area located 60 km northeast of Bratsk. The aircraft was damaged beyond repair and all three occupants escaped unarmed.
Probable cause:
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.

Circumstances:
Following an uneventful flight from Irkutsk-Magan Airport, the crew started the descent to Zheleznogorsk-Ilimskiy Airport in relative good weather conditions with a horizontal visibility of 20 km. On final, at an altitude of 400 meters, the three engine airplane collided with a Soviet Air Force Mil Mi-8 helicopter registered CCCP-22268. Inbound from Bratsk, the helicopter was completing a training mission with seven people on board. Following the collision, both aircraft dove into the ground and crashed in a wooded and hilly terrain located about 11 km from the airport, bursting into flames. All 40 occupants in both aircraft were killed.
Probable cause:
It was determined that the collision was the consequence of a poor ATC surveillance, causing both aircraft to initiate an approach without ensuring that they each maintained a minimum separation in accordance with published procedures. This situation allowed the helicopter to cut off the approach path of the aircraft. The lack of radio communications between the three parties concerned remained a contributing factor.
