## Analysis

THE ACFT HAD BEEN PARKED AT THE ARPT FOR ABOUT 7 MONTHS PRIOR TO THIS FLT. DURING THAT TIME, THE ENG HAD BEEN OVERHAULED. BEFORE TAKING OFF ON A MAINTENANCE TEST FLT, 37 GAL OF FUEL WAS ADDED TO THE CENTER TANK. ALSO, THE PLT WAS OBSERVED WORKING IN THE ENG AREA BEFORE TAKING OFF. AFTER TAKEOFF, THE ACFT WAS OBSERVED TO TURN TO A DOWNWIND LEG, THEN THE ENG BEGAN TO RUN ROUGH & FINALLY QUIT RUNNING. DURING AN EMERGENCY LANDING, THE ACFT HIT AN EMBANKMENT BEFORE REACHING THE RWY. BOTH OCCUPANTS RECEIVED HEAD INJURIES & COULD NOT REMEMBER DETAILS OF THE ACCIDENT. A POST ACCIDENT INSPECTION REVEALED A LOOSE B-NUT ON A FLEX LINE TO THE FUEL STRAINER. THE EXTERIOR OF THE ENGINE WAS BADLY DAMAGE. A TEARDOWN OF THE ENG DID NOT REVEAL ANY DISCREPANCIES THAT WOULD HAVE RESULTED IN A POWER LOSS.
