Analysis

The airplane was observed to make a touch and go. On climbout at an altitude of approximately 300 feet, the airplane was observed to enter a descending right turn and impact the ground on the right wing and nose. Post accident investigation found the tachometer stuck at approximately 2200 RPM and chord wise scratches were visible on one blade of the propeller. Fuel was found in the carburetor and no defects were found with the engine or airframe. The PIC who occupied the left seat said he did not remember what happened, and that the right seat pilot was operating the flight controls just prior to the accident.
