What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) On July 25, 2006 at approximately 1:00 p.m. CDT, a Cessna 182RG was destroyed by fire after a precautionary landing on runway 17 at the Mcalester regional airport, located in Mcalester Oklahoma. The training flight was being operated under title 14 code of federal aviation regulations, parts 91 and 141, from tulsa, Oklahoma to durant, Oklahoma, during visual meteorological weather conditions. The appropriately rated instructor pilot and his rated student pilot were not injured. According to statements made by the instructor pilot, he and his student were in cruise flight at 4,500 feet about 20 miles northwest of Mcalester when they sensed an odor of fuel from the position in the cockpit. Subsequently, the fuel pressure dropped to zero and the engine began to "sputter." The engine, according to the instructor pilot, operated intermittently for the remainder of the flight. On landing at the airport, the instructor pilot and his student heard a "pop" and felt intense heat near the rudder pedals. The instructor pilot stated that soon thereafter, he noticed flames coming into the cockpit from the floor. The instructor and student began emergency shutdown procedures and exited the aircraft during the landing rollout. Post accident inspection of the aircraft's engine and accessories revealed extensive damage or deformation to the fuel systems components. The engine driven fuel boost pump exhibited severe distortion in the form of molten metal and other contaminants. Steel braided fuel lines emanating from the carburetor, electric and engine driven fuel boost pumps, fuel pressure indicators were inspected with no abnormalities noted. Steel attachment fittings were found broken with 45 degree "necking" or "shear-lips." All aluminum fittings associated with fuel line attachments were either partially or fully consumed by fire. Inspection of the aircraft's maintenance records indicated that the carburetor had been removed and replaced on two occasions within the previous 12 months. The last records showing fuel line replacement was during an engine overhaul in 2003. The total time the fuel lines had been in service was 371 hours. Further review of the maintenance records were unremarkable, especially, those items related to fuel system maintenance, repair and subsequent return to service. Additional inspection and tesing is pending. A service difficulty report has been submitted by the operator. Weather conditions near the time of accident at Mcalester, OK, taken by flight service station personnel were as follows: winds 170 degrees at 12 knots gusting to 17 knots; visibility 10 statute miles, few clouds at 6,500 feet, temperature 36 degrees celsius, dewpoint 18 degrees celsius, and altimeter 29.91 hg.

POST ACCIDENT INSPECTION OF THE AIRCRAFT'S ENGINE AND ACCESSORIES REVEALED EXTENSIVE DAMAGE OR DEFORMATION TO THE FUEL SYSTEMS COMPONENTS. THE ENGINE DRIVEN FUEL BOOST PUMP EXHIBITED SEVERE DISTORTION IN THE FORM OF MOLTEN METAL AND OTHER CONTAMINANTS. STEEL BRAIDED FUEL LINES EMANATING FROM THE CARBURETOR, ELECTRIC AND ENGINE DRIVEN FUEL BOOST PUMPS, FUEL PRESSURE INDICATORS WERE INSPECTED WITH NO ABNORMALITIES NOTED. STEEL ATTACHMENT FITTINGS WERE FOUND BROKEN WITH 45 DEGREE "NECKING" OR "SHEAR-LIPS." ALL ALUMINUM FITTINGS ASSOCIATED WITH FUEL LINE ATTACHMENTS WERE EITHER PARTIALLY OR FULLY CONSUMED BY FIRE. INSPECTION OF THE AIRCRAFT'S MAINTENANCE RECORDS INDICATED THAT THE CARBURETOR HAD BEEN REMOVED AND REPLACED ON TWO OCCASIONS WITHIN THE PREVIOUS 12 MONTHS. THE LAST RECORDS SHOWING FUEL LINE REPLACEMENT WAS DURING AN ENGINE OVERHAUL IN 2003. THE TOTAL TIME THE FUEL LINES HAD BEEN IN SERVICE WAS 371 HOURS. FURTHER REVIEW OF THE MAINTENANCE RECORDS WERE UNREMARKABLE, ESPECIALLY, THOSE ITEMS RELATED TO FUEL SYSTEM MAINTENANCE, REPAIR AND SUBSEQUENT RETURN TO SERVICE. ADDITIONAL INSPECTION AND TESING IS PENDING. A SERVICE DIFFICULTY REPORT HAS BEEN SUBMITTED BY THE OPERATOR.
