## Analysis

DURING A CROSS COUNTRY FLIGHT, THE RIGHT ENGINE BEGAN TO RUN ROUGH. THE PILOT FEATHERED THE PROPELLER AND TURNED TO LAND AT THE AIRPORT. EN ROUTE, THE LEFT ENGINE BEGAN TO RUN ROUGH. UNABLE TO LAND AT THE AIRPORT, A FORCED LANDING WAS MADE ON A ROAD, WHERE, DURING THE LANDING ROLL, THE AIRPLANE STRUCK AN ABANDONED CAR AND COLLIDED WITH THE TERRAIN. INSPECTION OF THE ENGINE REVEALED THAT THE FUEL LINES TO BOTH ENGINES WERE PARTIALLY BLOCKED WITH AN UNKNOWN SUBSTANCE. THE PILOT REPORTED THAT IN THE MONTHS PRIOR TO THE ACCD THE LEFT ENGINE HAD LOST POWER AT LEAST 4-5 TIMES. AFTER EACH OCCURRANCE THE ENGINE HAD BEEN INSPECTED BY A MECHANIC. THE PROBLEMS THAT WERE FOUND RANGED FROM A CLOGGED OIL SEPARATOR TO LOW FUEL PRESSURE THAT WAS CORRECTED BY REPLACEMENT OF VARIOUS HOSES.
