Probable cause

A partial loss of engine power due to a compromised induction system.

NTSB narrative

The private pilot was attempting to take off on the experimental, amateur-built airplane's first flight. When the airplane was about 30-50 ft in the air, the engine experienced a partial loss of power and the pilot landed on the remaining runway. The airplane landed hard, the landing gear collapsed, and the airplane nosed over. Examination of the engine revealed several air leaks in the induction system, including the vacuum takeoff port cap on the carburetor and the rudder seal on the left induction manifold adapter. It is likely that the compromised induction system resulted in the partial loss of engine power.
