Analysis

The acft crashed during takeoff while on a pleasure flight. A witness stated that he saw the acft take off and climb outat a gradual climb to about 100 ft and then start a gradual descent to about 30 ft. at which time the acft nosed over and went almost vertically into the ground. The carburetor air filter came off and struck the prop causing severe vibration. The prop then struck the pilot and the acft plummeted to the ground.
