## Analysis

BEFORE TAKEOFF, THE ACFT HAD APRX 40 GAL OF FUEL IN THE MAIN TANKS & 10 GAL WAS ADDED TO EACH OF THE AUXILIARY TANKS. THE PLT TOOK OFF IN HAZY CONDITIONS FOR A SHORT FLT OF APPRX 10 MIN. WHILE ON DOWNWIND FOR A LANDING, HE SWITCHED FROM THE AUXILIARY TO THE MAIN TANKS. AS THE ACFT TURNED TO FINAL APCH, BOTH ENGS LOST POWER, SIMULTANEOUSLY. THE PLT WAS UNABLE TO START THE ENGS & LANDED THE ACFT SHORT OF THE RWY. DURING THE LANDING ROLL, THE LEFT MAIN GEAR FAILED. AN EXAMINATION OF THE ENGS & FUEL SYS REVEALED NO PREIMPACT DISCREPANCIES. THE RIGHT ENG WAS STARTED & IT OPERATED NORMALLY. THE LEFT ENG COULD NOT BE STARTED DUE TO IMPACT DAMAGE.
