During flight the propeller failed shedding one blade approximately 15 inches from the hub. The aircraft was observed to pitch up and enter a flat spin to impact. The propeller installed on the aircraft was a cut-down metal propeller, and the aircraft specifications required that only wood propellers be used. The logs indicated a wood propeller was installed on the aircraft and no history of the metal propeller was found. CAUSE: the installation of an unapproved metal propeller which led to a fatigue failure of a blade and loss of aircraft control.
