Read the full NTSB narrative
While at a cruise altitude of 2,500 feet msl the pilot reported that the airplane started to vibrate. He attempted to shut down the engine with no response. He elected to land at a nearby airport, and landed without incident. Examination of the airplane revealed that the propeller came loose from the flange. All of the propeller bolts were found backed out, and none of the bolts were safety wired. The pilot had just purchased the airplane. Examination of the airplane after the accident revealed that several inches of the leading edge of one blade of the propeller was missing. One of two propeller blades split in half from the center to the tip, the propeller bolts were found loose, and all evenly backed out approximately one quarter inch. No locking device or safety wires were attached to the bolt heads. The data sheet does not list the propeller for installation on this aircraft. There were no log book entries found to indicate that the propeller bolts were torqued or tracked on installation or at annual inspection.
