## Analysis

THE ACFT OVERRAN THE RWY DURING A NO-FLAP LANDING ROLL-OUT. THE PLT REPORTED THAT HE HAD ELECTRICAL FAILURE AFTER TAKEOFF AND RETURNED TO LAND BUT HE WAS UNABLE TO EXTEND THE FLAPS. THE APPROACH WAS HIGH AND FAST BUT THE PLT CONTINUED AND TOUCHED DOWN LONG. AS THE ACFT WENT OFF THE RWY END IT NOSED OVER. EXAMINATION OF THE ELECTRICAL SYSTEM FAILED TO REVEAL ANY FAILURE. INVESTIGATION REVEALED THE ACFT NEEDED A JUMP START PRIOR TO THE FLT.
