Analysis

While on a local flt, the acft crashed in lake Michigan about 1/2 mi from the shoreline. According to witnesses, it was flying over the water at about 100 ft, then pulled almost straight up to about 300 ft above the water, nosed over & went almost straight nose down until water impact. Later, the acft was recovered & examined, but no preimpact/mechanical malfunction or failure was found. The leading edge of the propeller blade tips were bent opposite the direction of rotation, the spark plugs were clean & fuel was found in the fuel distribution manifold.
