## Analysis

THE PLT INDICATED THAT AFTER LANDING THE ENG QUIT WHILE TURNING THE ACFT AROUND ON THE RWY. HE ATTEMPTED TO RESTART THE ENG SEVERAL TIMES BUT WAS UNABLE. THE PLT THEN EXITED THE ACFT AND PUSHED IT TO THE RWY SHOULDER. A LOCAL MECHANIC WHO WAS ALSO A PLT, ARRIVED AND ASSISTED THE PLT. THE MECHANIC ATTEMPTED TO START THE ENG. THE PLT WHO WAS OUTSIDE OF THE ACFT AT THE TIME NOTICED A FIRE IN THE ENG COWLING. THE MECHANIC THEN SHUT THE FUEL OFF AND EXITED THE ACFT ALONG WITH THE PLT'S PAX. THE PLT INDICATED THAT THERE WAS NO FIRE EXTINGUISHER NEARBY AND THE FIRE WAS ALLOWED TO SPREAD, DESTROYING THE ACFT. THE CESSNA PILOT'S OPERATING HANDBOOK CAUTIONS PILOT'S ABOUT THE HAZARD OF FIRE IN THE INDUCTION SYSTEM IF FUEL IS ALLOWED ACCUMULATE. THE HANDBOOK STATES, 'PUMPING THE THROTTLE MAY CAUSE RAW FUEL TO ACCUMULATE IN THE INTAKE AIR DUCT, CREATING A FIRE HAZARD IN THE EVENT OF A BACKFIRE. IF THIS OCCURS, MAINTAIN A CRANKING ACTION TO SUCK THE FLAMES INTO THE ENGINE.'
