Incident
Following departure from Terney Airfield, the aircraft climbed to an altitude of 30 meters. At that point, it adopted an excessive angle of attack while maintaining a nose-up attitude. The aircraft then banked to the left, entered an aerodynamic stall, and crashed in flames into a potato field. The captain and five passengers were injured; the remaining ten occupants were killed.
Investigation
Investigators determined that the crew had not properly prepared for the flight. The aircraft's total weight exceeded its maximum takeoff weight by 449 kilograms. Furthermore, the center of gravity was found to be outside the prescribed envelope, positioned too far aft. These weight and balance conditions rendered the aircraft unstable for the initial climb phase.
Probable Cause
The probable cause of the accident was the crew's failure to prepare the flight properly, resulting in the aircraft being 449 kg over maximum takeoff weight and with an excessively aft center of gravity. This caused the airplane to enter a high angle of attack during the initial climb, leading to a stall and subsequent crash.
