The twin engine aircraft departed Kostroma Airport at 0809LT on a flight to Ivanovo, carrying eight passengers and two pilots. After takeoff, while climbing in marginal weather conditions, the crew was instructed to report once the altitude of 1,800 meters would be reached but the crew failed to respond. The aircraft entered an uncontrolled descent and crashed in a wooded area located 11 km north of the airport. The aircraft was destroyed and all 10 occupants were killed.

Probable cause:

The exact cause of the accident could not be determined with certainty as investigations were hampered because the aircraft was not equipped with CVR/FDR. Nevertheless, it is believed that the pilot-in-command lost control of the airplane after he suffered a spatial disorientation caused by the malfunction/dysfunction of the horizontal gyro.

Circumstances:

In the morning, the crew completed a spraying mission on wooded areas. At 1015LT, when the mission was over, the crew allowed tree passengers to embark and departed for Soligalich. Few minutes later, the crew encountered marginal weather conditions with low clouds, haze and rain falls. While flying at an altitude of 285 meters, the airplane struck tree tops and crashed in a wooded area. All five occupants were killed.

Probable cause:

It was determined that the crew allowed passengers to embark without prior authorization. At the time of the accident, both pilots were intoxicated as they consumed alcohol the evening before the flight. Various analysis revealed a blood alcohol level of 1,16‰ for the captain and 0,75‰ for the copilot.

Circumstances:

The aircraft departed Kostroma Airport at 0730LT with one passenger and seven crew on board. They were in charge to make aerial photography of the railroad from Neya to Svesha via Manturovo and Sharya. After two hours and ten minutes of flight, the left engine failed. The captain decided to divert to Sharya when the right engine overheated shortly later. In such conditions, he decided to attempt an emergency landing when the airplane lost height, struck trees and crashed in a dense wooded area located on km 711, some 600 meters from the railroad. The passenger was unhurt while all seven crew members were injured. Eighteen hours later, the captain died from his injuries. The airplane was destroyed.

Probable cause:

Failure of the left engine in flight due to the dysfunction of the carburetor. The high outside temperature was considered as a contributing factor as the crew was unable to maintain a safe altitude on one engine in such conditions.
