Accident Details
The accident occurred at Gdynia-Babie Doły Air Force Base during a training sortie. The aircraft was on final approach with one engine intentionally shut down. As it slowed, the aircraft entered a stall. The crew decided to execute a go-around, but during the maneuver, the aircraft struck trees at the end of the runway and crashed. All four individuals on board were killed.
Sequence of Events
According to the investigation, the pilot in command was under instruction and was joining the traffic pattern for a final approach with one engine inoperative. During the final approach, the pilot selected full flaps, contrary to the approved Airplane Flight Manual (AFM) procedure, which limits flap extension to a maximum of 25 degrees. When power was applied for the go-around, the pilot lost directional control. The flight instructor did not intervene to take control of the aircraft.
Probable Cause
The official probable cause of the accident was the pilot in command's deviation from standard procedures by selecting full flaps on final approach, which led to a stall and loss of control. Additionally, the pilot failed to maintain directional control during the go-around, and the flight instructor did not assume control of the aircraft in time.
