DG-400 lands hard with a tailwind after its engine stops on a self-launch
At a competition at Šumperk, the pilot of a DG-400 was unhurt and the glider substantially damaged when its engine stopped at 49 m on a self-launch and he landed hard in a field with a tailwind. With no safe landing ahead and buildings, trailers and people to the right, he turned 120° left. The dead engine stayed extended, and with a strong tailwind the speed fell close to the stall in the flare; the glider struck on its wheels and right wingtip, bounced and ground-looped. The engine probably stopped from air in the fuel line. The cause was given as the piloting, shaped by the forced choice of field, the extended engine and the tailwind.
- Self-launch from RWY 36: On a competition day at Šumperk the pilot self-launched from RWY 36 at 14:13; the take-off roll was slow in tall grass on the slightly rising runway.
- Engine stops at about 49 m: At about 49 m AGL, 150–200 m before the runway's end, the engine stopped. The pilot lowered the nose to about 100 km/h and left the engine extended.
- Turn of about 120° to a field: He judged a landing ahead no longer safe; with buildings, trailers and people to the right and a tow about to launch behind, he turned about 120° left towards a sown field.
- Tailwind, engine still extended: The turn ended with a strong tailwind. With the dead engine still extended, the speed fell from about 100 km/h to close to the stall in the flare.
- Hard landing, bounce, ground loop: The glider struck the field on its main wheel, tailwheel and right wingtip, bounced about 20 m, touched again and ground-looped to the right; the right wing's torsion box collapsed.
