The NTSB's narrative final · quoted from the NTSB record

WHILE CRUISING AT 9500 FT MSL, THE ENGINE BEGAN RUNNING ROUGH. THE PILOT DIVERTED TO RIALTO MUNICIPAL AIRPORT FOR A PRECAUTIONARY LANDING. WHILE ON BASE LEG, THE ENGINE QUIT COMPLETELY. FROM THAT POSITION, THE PILOT WAS UNABLE TO REACH THE RUNWAY. THE AIRCRAFT TOUCHED DOWN ABOUT 1/4 MILE SHORT, AND DURING THE LANDING ROLL, IT COLLIDED WITH A DITCH. AN INVESTIGATION REVEALED THAT THE ENGINE CRANKSHAFT HAD FAILED FROM FATIGUE. PREVIOUSLY, THE AIRCRAFT HAD BEEN INVOLVED IN A GEAR-UP LANDING. NO RECORD WAS FOUND TO VERIFY AN INSPECTION OF THE CRANKSHAFT IN ACCORDANCE WITH THE ACCEPTED PRACTICES FOLLOWING A PROPELLER STRIKE.
