What happened
The incident occurred during a local training flight conducted over the city of Warsaw. While operating at an altitude deemed insufficient for safe clearance, the aircraft collided with overhead telephone wires. This impact caused the plane to lose control and descend rapidly onto several buildings situated along Kopinska Street in the Ochota district.
Upon striking the structures, the aircraft burst into flames. The combination of the high-energy impact and the subsequent post-crash fire resulted in the total destruction of the airframe. Significant damage was also sustained by the multiple buildings hit during the crash sequence.
Tragically, both members of the flight crew were killed in the accident. There were no survivors among the personnel on board the aircraft.
Findings
The official investigation identified that the primary factor leading to the collision was the operational altitude. The crew was flying at a level that was too low to safely clear obstacles such as telephone wires, which directly precipitated the chain of events resulting in the crash.
