Category:Accident
Location:Großrückerswalde Airfield - EDAG -   Germany
Phase: Approach
Nature:Private
Departure airport:EDAG
Destination airport:EDAG
Investigating agency: BFU Germany
Narrative:
Mid-air collision between a Flight Design CTSW (D-MHBA) and an ASK-21 glider (D-5658) during an 'Open Day' at Großrückerswalde Airfield - EDAG, during approach. The ultralight crashed to the ground, killing both occupants. The glider managed to land at the airfield.

BFU Conclusions:
The aircraft accident is due to the fact that the pilots had no visual contact with each other during the final approach and that the two aircraft collided during the further course of the flight. The UL subsequently entered an uncontrolled flight condition, which could no longer be sufficiently intercepted by the pilot due to the too low flight altitude.
Contributing factors were:
- Insufficient communication between the pilots involved and the responsible flight controller during landing preparations.
- Landing classification of the ulm at low altitude and thus late recognition of the aircraft by the flight controller during the final approach.
- Unfavourable seat selection of the glider pilot, with thereby restricted field of vision for airspace observation during the landing division from the rear seat.
