Incident Overview
A training flight at Vnukovo Airport ended in a crash after the aircraft encountered control difficulties and engine power loss shortly after takeoff. The crew had completed four successful touch-and-go maneuvers before initiating another takeoff.
Sequence of Events
Immediately after liftoff, at an altitude of approximately 20 meters, the aircraft experienced severe vibrations and became unstable. As the climb continued, at around 70 meters, both engine number 1 and engine number 3 simultaneously lost power. The captain then decided to perform an emergency landing.
During the landing attempt, the aircraft struck tree tops and crashed in flames in a wooded area. All four occupants sustained minor injuries, while the aircraft was destroyed.
Official Findings
The investigation identified a technical problem with the slats, which deployed at an inappropriate angle after rotation. However, the cause of the power loss on the two engines remains undetermined.
