Narrative:
Ex-USAF T-28A 49-1669
THE PILOT/MECHANIC HAD RECENTLY RE-INSTALLED A REBUILT ENGINE IN THE AIRCRAFT AND PERFORMED A VERY SHORT RUN-UP PRIOR TO TAKEOFF. WITNESSES STATED THE AIRCRAFT ENGINE MADE POPPING NOISES AND WAS BELCHING BLACK SMOKE DURING THE TAKEOFF ROLL. THE AIRCRAFT
BECAME AIRBORNE AND MUSHED AROUND A LEFT 180 DEGREE TURN BEFORE CRASHING IN A SWAMPY AREA AT THE AIRPORT EDGE. EXAMINATION OF THE IGNITION HARNESS AND SPARK PLUGS REVEALED THAT A 7 MM HARNESS WAS INSTALLED UTILIZING 5 MM SPARKPLUG CONNECTORS. SIX SPARKPLUGS EXHIBITED EVIDENCE OF FLASHOVER IN THE SPARKPLUG CONNECTOR WELLS. THIS CAUSED A PARTIAL POWER LOSS OF THE TOTAL REQUIRED POWER AVAILABLE AND NECESSARY FOR FLIGHT.
