Read the full NTSB narrative

THE PILOT WAS PRACTICING TOUCH AND GO TAKEOFFS AND LANDINGS. THE FLAPS WERE FULLY EXTENDED DURING THE LANDING PHASE OF THE MANEUVER. DURING THE SECOND LANDING ROLL THE PILOT RAISED THE FLAP HANDLE AND BEGAN THE TAKEOFF ROLL. WHEN THE AIRPLANE LIFTED OFF THE PILOT OBSERVED THAT THE FLAPS REMAINED FULLY EXTENDED AND WOULD NOT RAISE. THE PILOT WAS ABLE TO TURN THE AIRPLANE, BUT COULD NOT GAIN ADDITIONAL ALTITUDE WITHOUT THE STALL WARNING HORN ACTIVATING. THE PILOT TURNED THE AIRPLANE TOWARD THE AIRPORT BUT OBSERVED A POWERLINE. THE PILOT WAS UNABLE TO CLIMB OVER THE POWERLINE AND BANKED THE AIRPLANE. THE AIRPLANE STALLED DURING THE BANKING TURN. THE POST ACCIDENT INVESTIGATION REVEALED THAT THE FUSE HAD BLOWN AND WAS THE WRONG TYPE OF FUSE. THE FLAP MOTOR TERMINALS WERE CORRODED AND THE FLAP MOTOR OPERATED INTERMITTENTLY UNDER ALL LOAD CONDITIONS.
