The NTSB's narrative final · quoted from the NTSB record
THE CESSNA 172 WAS INVOLVED IN A CARBURETOR FIRE ON 1/13/90 & TAKEN TO A HANGAR WHERE THE AIR CLEANER & CARBURETOR WERE REMOVED. THE FUEL LINE WAS NOT CAPPED & THE LOWER COWLING WAS REATTACHED WITH ONLY TWO SCREWS HOLDING IT. NO PLACARD WAS PLACED IN THE COCKPIT NOR WAS THE KEY MADE UNAVAILABLE FOR RENTAL. THE PLANE WAS RETURNED TO THE LINE FOR PARKING. THREE DAYS LATER, A PILOT CAME TO THE AIRPORT, ASKED THE ATTENDANT FOR THE KEY & PROCEEDED TO THE PLANE. HE SAID HE MADE A PREFLIGHT 'USING THE MANUAL.' HE THEN ENTERED THE COCKPIT & ATTEMPTED TO START THE ENGINE. HOWEVER, A FIRE ERUPTED & THE PLT EXITED THE AIRPLANE THROUGH THE FIRE, RECEIVING BURNS.
