FARMINGDALE, NY, USA
N90DD
STINSON 108
THE CARBURETOR HAD BEEN PREVIOUSLY REMOVED & REWORKED, THEN WAS REINSTALLED. AFTER THE INSTALLATION, WHICH INCLUDED A LEAK CHECK, THE PLT GOT INTO THE LEFT FRONT SEAT & THE PASSENGER/MECHANIC GOT INTO THE RIGHT FRONT SEAT. THE PLT PRIMED THE ENG, THEN MADE A START. AFTER STARTING, THE ENG RAN FOR APRX 20 SECONDS, THEN STOPPED. THE OCCUPANTS DISCUSSED THE PROBLEM & DECIDED THAT THE FUEL LINE WAS PROBABLY 'AIR BOUND.' A DECISION WAS MADE TO KEEP THE ENG RUNNING BY USING THE PRIMER. AFTER RESTARTING, THE ENG CONTINUED TO RUN, BY USE OF THE PRIMER, FOR 30 TO 40 SEC, THEN THE PLT OBSERVED A FIRE IN THE LOWER RIGHT CORNER OF THE COCKPIT. THE OCCUPANTS EVACUATED THE BURNING PLANE, BUT THE PLT FELL & THE PASSENGER RETURNED TO HELP. AT ABOUT THAT TIME, THE RIGHT WING TANK EXPLODED & BOTH OCCUPANTS WERE BURNED. AN EXAM REVEALED THAT THE MAIN FUEL LINE FROM THE GASCOLATOR TO THE CARBURETOR HAD BROKEN. THE PLT DIED TWO DAYS LATER.
