## Analysis

POWER LOSS OCCURRED ABOUT 7 MIN AFTER TAKEOFF. THE PLT TURNED BACK TOWARD THE ARPT BUT WAS UNABLE TO REACH THE ARPT DUE TO A 15-20 KT HEADWIND. THE ACFT LANDED HARD COLLAPSING THE LANDING GEAR AFTER THE PLT MUSHED THE ACFT TO CLEAR WIRES. EXAMINATION & FLOW TEST OF THE FUEL CONTROLLER REVEALED NUMEROUS DISCREPANCIES, OBSOLETE PARTS & FLOW CHARACTERISTICS WELL BELOW ACCEPTABLE STANDARDS. THE ENG WAS OVERHAULED IN 1976. A YELLOW SERVICEABILITY TAG IN THE ACFT RECORDS STATED THAT THE UNIT HAD BEEN OVERHAULED BY A REPAIR STATION IN TEXAS. HOWEVER THE SEAL ON THE SAFETY WIRE WAS STAMPED WITH AN IDENTIFICATION OF A LOS ANGELES BASED OVERHAULER THAT CLOSED SHOP IN 1969.
