Narrative:
THE PILOT REPORTED THAT DURING THE INITIAL CLIMB-OUT AFTER TAKEOFF, A CRACKING SOUND WAS HEARD, AND THEN A SEVERE VIBRATION WAS FELT. THE PILOT SHUT THE ENGINE DOWN AND EXECUTED A FORCED LANDING TO AN OPEN FIELD. DURING THE LANDING ROLL ON ROUGH TERRAIN, THE LANDING GEAR COLLAPSED AND THE LOWER WING CONTACTED THE SURFACE. POSTCRASH INSPECTION OF WOOD PROPELLER REVEALED THAT THE OUTBOARD SIX INCHES OF ONE BLADE HAD SEPARATED IN-FLIGHT. THE MANUFACTURER OF THE EXPERIMENTAL PROPELLER REPORTED THAT THE WOOD MATERIAL WAS A TYPE OF MAHOGANY, AND THAT ONLY 5 WERE MANUFACTURED BEFORE DISCONTINUING THE USE OF THIS PARTICULAR WOOD.
