## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) THE AIRCRAFT ENGINE LOST POWER ABOUT 10 MINUTES AFTER DEPARTING SEBASTIAN, FL (X26), AND A FORCED LANDING WAS MADE IN A FIELD WHERE THE AIRPLANE IMPACTED A DITCH. POST-ACCIDENT TEARDOWN AND EXAMINATION OF THE ENGINE ON 7/16/03 REVEALED THAT THE CRANKSHAFT HAD FRACTURED AT THE NO.3 CYLINDER CONNECTING ROD JOURNAL. UNAIDED VISUAL EXAMINATION OF THE ENGINE COMPONENTS REVEALED NO EVIDENCE OF LACK OF LUBRICATION OR CRANKCASE FRETTING. REVIEW OF THE ENGINE RECORDS AND DISCUSSION WITH THE AIRCRAFT OWNER REVEALED THAT THE ENGINE HAD BEEN DISASSEMBLED AND REASSEMBLED ABOUT 7 MONTHS AND 88 FLIGHT HOURS PRIOR TO THIS MISHAP. THE OWNER REPORTED THAT THIS WAS NECESSITATED BY A CAMSHAFT LOBE FAILURES AT THE #1 & #2 CYLINDERS. THE CRANKSHAFT WAS POLISHED BY AN AUTOMOTIVE MACHINE SHOP PRIOR TO REASSEMBLY, AND THE CAMSHAFT WAS REPLACED WITH A "YELLOW-TAGGED" CAM. BOTH THE NON-MECHANIC OWNER AND AN FAA CERTIFICATED MECHANIC ACCOMPLISHED THE ENGINE MAINTENANCE.
