The experimental airplane impacted terrain and objects during a forced landing following an in flight loss of engine power. The pilot and passenger sustained minor injuries. The pilot stated, "I add a small amount of power when the engine quit, a large bang, not mechanical but carbaroter [carburetor] or fuel related, like a backfire, and no power - the engine poped several times. I changed the throttle settings several times, turned on the fuel boost pump [and] the fuel injector. No help. Turned to the right to a hay field, tried to miss the 2,000 lb hay rolls, no place to land-jumped the fence at the end-came down on the tailwheel first then on the main gear-got the prop first on the ground, then hit the hay roll. Hit the right side of engine and right wings. The aircraft nosed over and slid on the engine for approx 20ft. then over on its back." The spark plugs exhibited a dark black color. The temperature and dew point plot on a Transport Canada Carburetor Icing chart intersected in the serious icing-descent power range. The pilot stated, "I found out after the fact that the engine has a tendency to flood out. ... There is a carburetor mod for the engine which we put on the next a/c we built and it, the engine, Vedeneyev M14PF, has ran without any problems now for 40 hrs. Conclusions: The engines and carburetors need to be checked and tuned for our fuels here in the US. Check for the carburetor mods that are out there and talk to someone who has one and is flying one now to learn its secrets."
Probable Cause: The unsuitable terrain the pilot selected during his emergency landing. Factors were the hay rolls and the loss of engine power for undetermined reasons.
