THE FLIGHT WAS CRUISING AT 7500' WHEN THE ENGINE STARTED TO RUN ROUGH 12.2 NAUTICAL MILES FROM NORFOLK AIRPORT. THE PILOT STATED THAT HE DID NOT CHANGE THE PROPELLER SETTING UNTIL HE WAS OVERHEAD THE AIRPORT. THEREAFTER THERE WAS A LOUD EXPLOSION AND THE OIL ACCESS DOOR BLEW OPEN AND PIECES OF THE ENGINE EXITED THE AIRPLANE. DURING THE FORCED LANDING ON RUNWAY 23 THE AIRPLANE TOUCHED DOWN ON THE GRASSY AREA. EXAMINATION REVEALED THE NO. 2 CYLINDER ASSEMBLY, PISTON AND CONNECTING ROD SEPARATED FROM THE CRANKCASE AT THE CYLINDER HOLD-DOWN STUD AREA.
