The NTSB's narrative final · quoted from the NTSB record
THE AIRLINE TRANSPORT PILOT, WHO IS ALSO AN AIRFRAME AND POWERPLANT MECHANIC, WAS CONDUCTING A LOCAL AREA MAINTENANCE TEST FLIGHT. THE ENGINE BEGAN MISFIRING SHORTLY AFTER TAKEOFF. THE PILOT EXECUTED A RIGHT TURN TO RETURN TO THE AIRPORT, BUT INADVERTENTLY STALLED THE AIRPLANE. THE AIRPLANE NOSED DOWN SHARPLY AND CRASHED. EXAMINATION OF THE ENGINE FUEL SYSTEM REVEALED THAT THE FUEL INLET PASSAGE WAS CLOGGED WITH AN UNIDENTIFIED BLACK, SPONGE-LIKE MATERIAL. THIS CONDITION PREVENTED FUEL FROM GETTING TO THE FUEL INJECTOR ASSEMBLY RESULTING IN FUEL STARVATION. ALSO, TWO OF THE FUEL INJECTOR NOZZLE SCREENS WERE OBSTRUCTED; THE REMAINING SCREENS WERE PARTIALLY OBSTRUCTED. A FIXED-BASE OPERATOR AND THE REGISTERED OWNER REPORTED THAT THE FUEL NOZZLES HAD RECURRING CLOGGING. THE PILOT WAS COMPLETING A 100-HOUR INSPECTION AT THE TIME OF THE ACCIDENT. THE ENGINE EXAMINATION DISCLOSED EXTENSIVE FRETTING OF BOTH CRANKCASE HALVES AND ALL OF THE CYLINDERS BASES. THE ENGINE EXAMINATION, HOWEVER, DID NOT REVEAL ANY ABNORMALITIES WHICH WOULD HAVE PREVENTED THE ENGINE FROM PRODUCING POWER.
