Investigation Summary
The flight was a training exercise intended to practice 'touch-and-go' landings and engine-out procedures. During the climb-out from Runway 28, the instructor pilot simulated a failure of the left engine. The trainee pilot applied incorrect rudder input, causing the aircraft to yaw and roll uncontrollably to the left. The aircraft lost altitude and struck the ground before sliding into the international terminal apron, where it collided with a parked Aeroflot aircraft and several ground personnel.
Final Conclusions
The investigation concluded that the primary cause was the trainee's incorrect rudder application during a simulated engine failure, which was not corrected in time by the instructor pilot. The aircraft's low altitude during the maneuver left no margin for recovery once the upset occurred.

Systems & Failure Modes
Rudder
The primary control surface used to counter yaw; incorrect application during engine-out simulation led to the loss of control.
Flight Controls
The mechanical linkages and hydraulic boosters that translate pilot input to the aircraft's control surfaces.

Safety Actions & Advisories
Training Protocol Revision
Recommendations were made to ensure that simulated engine failures are conducted at safer altitudes and that instructors maintain a higher state of readiness to intervene.
