What happened
A training mission originating from Cologne-Bonn Airport ended in a fatal accident during the initial stages of flight. While the aircraft was performing its takeoff roll and approaching V2 speed, it experienced a lateral deviation to the left, causing it to exit the runway surface. The aircraft traveled alongside the runway for approximately 600 metres while in a rolling motion before re-entering the paved surface.
Following this excursion, the aircraft managed to lift off from the ground. However, the flight was immediately interrupted when the aircraft overturned, landing upside down. The impact resulted in the aircraft bursting into flames. There were four fatalities among the occupants of the aircraft.
Findings
The accident occurred during the takeoff phase, specifically characterized by a deviation from the runway centerline near the point of rotation.
