What happened
On March 16, 2016, a Schempp-Hirth Standard Cirrus TOP glider departed from the Ummern glider airfield via a self-launch. The pilot, performing his first flight of the year, intended to test all aircraft systems prior to an upcoming annual airworthiness inspection. After reaching an altitude of approximately 300 meters with the retractable engine stowed, the pilot utilized thermals to climb to roughly 1,000 meters, conducting various flight paths southwest of the airfield.
Approximately 40 minutes into the flight, the pilot attempted to establish a landing pattern toward runway 130°. However, about 800 meters before reaching the airfield, the aircraft struck a field. The impact caused the glider to capsize, resulting in the destruction of the aircraft and leaving the pilot seriously injured.
The investigation
The BFU investigation examined the wreckage and the flight circumstances. The aircraft, a single-seat composite glider with a retractable engine, was found with the engine mounting in the operational position and the fuel system functional, with both small tanks filled. The investigation of the propeller blades revealed multiple fractures. The aircraft's landing gear was extended, and the airbrake flaps were deployed. The investigation found no evidence of technical defects in the aircraft's systems or components.
Findings
- The aircraft struck the ground at a field approximately 800 meters from the airfield.
- The impact involved the nose of the fuselage and the right wing, ultimately leaving the aircraft in an inverted position.
- The investigation found no evidence of mechanical failure or technical malfunctions contributing to the accident.
