Accident Summary
The accident occurred during the takeoff initial climb phase. The left-seat pilot had been hired by the right-seat pilot to ferry the airplane from Germany to Turkey. A four-tank ferry fuel system had been installed, but no weight and balance check was performed before the flight.
Accident Details
During the takeoff attempt, the aircraft failed to climb. Post-accident calculations revealed that the airplane was overweight and the center of gravity was aft of the rear limit. The left wing struck trees, and the right wing impacted two fences. After colliding with terrain, the aircraft caught fire. Both occupants were killed.
Probable Cause
According to the official investigation findings, the probable cause for the in-flight collision with an object involved the following factors attributed to the pilot in command: inadequate preflight planning/preparation, exceeded aircraft weight and balance, premature lift-off, and inadequate airspeed. Additionally, an object (tree) and an object (fence) were identified as related factors. The subsequent in-flight collision with terrain/water occurred during the takeoff initial climb.
