The occurrence

On 26 July 2019, a Cessna 182N was conducting tow operations at the Black Diamond/Cu Nim Gliding Club airport (CEH2). A Schleicher ASK 21 dual-seat glider belonging to the club was operating at CEH2 with an instructor and student on board. The Cessna departed Runway 07 with the glider in tow and proceeded to climb to 2000 feet above the aerodrome, at which time the glider released from the tow plane. A few minutes later, the glider and the airplane collided approximately 0.5 nm southwest of the threshold of Runway 07. In the collision, the vertical and horizontal stabilizers were separated from the glider. The glider entered a dive from which it did not recover. The tow plane sustained damage to the propeller and right wing. However, the pilot of the airplane managed to perform a successful forced landing with idle power onto Runway 14. The student and instructor in the glider were both fatally injured. The tow pilot was not injured.
