Incident Overview
A training aircraft crashed in a field 12 kilometers south of Ramenskoye Airport, southeast of Moscow, resulting in the deaths of all nine occupants. The aircraft was engaged in a local training mission at the time of the accident.
Flight Details
The aircraft carried three instructors, five student-pilots, and one passenger aged 15. It departed from Ramenskoye Airport for the training flight. While cruising at an altitude of 2,100 meters, the aircraft was within clouds.
Accident Sequence
While in cruise, the aircraft encountered turbulence and subsequently lost control. It entered an uncontrolled descent and impacted the ground in a 70° nose-down attitude. The impact totally destroyed the aircraft. Wreckage debris included parts of the left wing found approximately 400 meters from the main fuselage.
Investigation Findings
The investigation determined that control was lost when severe turbulence was encountered in flight. This caused the left wing and elevators to partially detach as the aerodynamic forces exceeded their certification limits. All nine occupants were killed in the crash.
