## Analysis

DURING A CROSS COUNTRY PERSONAL FLIGHT, THE PIC NOTICED AN EXCESSIVELY HIGH OIL TEMPERATURE. HE SAID HE ENRICHED THE FUEL MIXTURE, AND WHEN THAT FAILED TO COOL THE ENGINE, HE REVERSED HIS COURSE BACK TO HIS DEPARTURE APT. SHORTLY AFTER HIS REVERSAL OF COURSE, THE ENGINE FAILED, AND AN EMERGENCY LDG WAS ATTEMPTED. DURING THE LANDING ROLL, THE AIRCRAFT STRUCK A SERVICE ROAD AND NOSED OVER. THE LDG WAS MADE DOWNWIND, WITH THE WIND VELOCITY OF 13 KNOTS GUSTING TO 20. POST ACCIDENT ENGINE INSPECTION AND RUN UP REVEALED NO MECHANICAL MALFUNCTION. THE FUEL LINE WAS ROUTED ABNORMALLY CLOSE TO THE EXHAUST MANIFOLD AND HAD NO PROTECTIVE SHIELDING.
