Probable cause

Carburetor ice due to the pilot's improper use of carburetor heat, and failure of the pilot to maintain control of the airplane after the engine lost power. The weather (carburetor icing) condition was a related factor.

Sequence of events

Analysis

The pilot experienced a reduction in engine power about 400 feet above the ground while performing a rolling maneuver. This was the third roll near his home as his family watched. Reportedly, the engine 'stalled,' the pilot lost control of the airplane, and it crashed in a wooded area. Weather conditions were conducive to the formation of carburetor icing. The airplane was not certified for rolls. Wreckage examination failed to disclose any preimpact part failure or malfunction. The airplane was destroyed by impact forces and a post-crash fire.
