From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(.19) On March 14, 1999, about 1828 Alaska standard time, a wheel equipped Cessna 180G airplane, N4721U, sustained substantial damage during an emergency landing at the Fairbanks International Airport, Fairbanks, Alaska. The airplane was being operated as a visual flight rules (VFR) local area personal flight when the accident occurred. The airplane was operated by the pilot. The certificated commercial pilot, the sole occupant, was not injured. Visual meteorological conditions prevailed. The flight originated at the Fairbanks airport at 1825. During a telephone conversation with the national transportation safety board (NTSB) investigator-in-charge (iic), on March 15, 1999, at 1115, the pilot reported that after departure, he reduced engine power to level the airplane at 1,500 feet, which is the airport traffic pattern altitude. The engine began to run rough, and he began an emergency landing approach to the ski strip at the Fairbanks airport. The engine roughness diminshed, and the pilot was cleared to land on runway 1R. The pilot said the engine then quit. The airplane touched down in an area of snow between the end of the ski strip, and the approach end of runway 1R. The airplane then nosed over, and received damage to the vertical stabilizer, the rudder, and the left wing lift strut. (.4) the certificated commercial pilot pushed the airplane out of a hanger and sumped the wing fuel tanks. The airplane remained outside throughout the day while the ambient temperature warmed. No further sumping of the wing tanks was conducted. After departure, the pilot reduced the engine power to level the airplane at the airport traffic pattern altitude. The engine began to run rough, and the pilot began an emergency landing approach to a snow-covered airstrip located near the approach end of an asphalt runway. The engine roughness diminished, and the pilot was cleared to land on the larger asphalt runway. The engine then quit. The airplane touched down in an area of snow between the end of the small airstrip and the beginning of the asphalt runway. The airplane nosed over, and received damage to the vertical stabilizer, the rudder, and the left wing lift strut. An examination of the airplane revealed a wrinkle in the left wing fuel bladder, and 3 ounces of water in the gascolator.

THE ENGINE BEGAN TO RUN ROUGH, AND HE BEGAN AN EMERGENCY LANDING APPROACH TO THE SKI STRIP AT THE FAIRBANKS AIRPORT. THE ENGINE ROUGHNESS DIMINSHED, AND THE PILOT WAS CLEARED TO LAND ON RUNWAY 1R. THE PILOT SAID THE ENGINE THEN QUIT. THE AIRPLANE TOUCHED DOWN IN AN AREA OF SNOW BETWEEN THE END OF THE SKI STRIP, AND THE APPROACH END OF RUNWAY 1R. THE AIRPLANE THEN NOSED OVER, AND RECEIVED DAMAGE TO THE VERTICAL STABILIZER, THE RUDDER, AND THE LEFT WING LIFT STRUT. (.4) THE CERTIFICATED COMMERCIAL PILOT PUSHED THE AIRPLANE OUT OF A HANGER AND SUMPED THE WING FUEL TANKS. THE AIRPLANE REMAINED OUTSIDE THROUGHOUT THE DAY WHILE THE AMBIENT TEMPERATURE WARMED. NO FURTHER SUMPING OF THE WING TANKS WAS CONDUCTED. AFTER DEPARTURE, THE PILOT REDUCED THE ENGINE POWER TO LEVEL THE AIRPLANE AT THE AIRPORT TRAFFIC PATTERN ALTITUDE. THE ENGINE BEGAN TO RUN ROUGH, AND THE PILOT BEGAN AN EMERGENCY LANDING APPROACH TO A SNOW-COVERED AIRSTRIP LOCATED NEAR THE APPROACH END OF AN ASPHALT RUNWAY. THE ENGINE ROUGHNESS DIMINISHED, AND THE PILOT WAS CLEARED TO LAND ON THE LARGER ASPHALT RUNWAY. THE ENGINE THEN QUIT. THE AIRPLANE TOUCHED DOWN IN AN AREA OF SNOW BETWEEN THE END OF THE SMALL AIRSTRIP AND THE BEGINNING OF THE ASPHALT RUNWAY. THE AIRPLANE NOSED OVER, AND RECEIVED DAMAGE TO THE VERTICAL STABILIZER, THE RUDDER, AND THE LEFT WING LIFT STRUT. AN EXAMINATION OF THE AIRPLANE REVEALED A WRINKLE IN THE LEFT WING FUEL BLADDER, AND 3 OUNCES OF WATER IN THE GASCOLATOR.
