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.

Acft landed downwind on a dirt strip and a gust of wind caught the tail and flipped the acft over. (.4)as the pilot approached the agricultural application airstrip, he decided that he would land downwind so that he would end his landing roll near the equipment that would be used to load the aircraft. After the aircraft touched down, the pilot became uncomfortable with the downwind landing, and elected to make a go-around. He applied power two separate times during the attempted go-around, but both times the engine coughed and sputtered and would not accelerate. The pilot therefore decided to abort the go-around, and attempted to stop the aircraft in the remaining runway. According to the pilot, as the aircraft was slowing, the tailwind picked up the aft end of the aircraft and caused it to nose over. In a post- accident telephone interview, the pilot said that he had failed to readjust the engine fuel mixture from its more-lean cruise setting prior to landing. He further stated that the engine had been working fine, and that he felt sure that if he had adjusted the mixture prior to landing that the engine would have accelerated wh en he added power for the go-around. (-23)airplane was flown from rigby Idaho to a dirt strip 3 miles nw of Idaho Falls id. According to the pilot, he elected to land with a tailwind bacause a landing in that direction would allow him to come to a stop near the equipment that was going to be used to load chemicals in the airplane. The pilot stated he became uncomfortable with the downwind landing and elected to go-around. When he applied power a second time the engine coughed and failed to accelerate, the pilot retarded the power and attempted to complete the landing. The pilot brought the stick to full-aft the tail wheel settled onto the terrain as the airplane slowed the tailwind lifted the tail and nosed over. The pilot stated he leaned the mixture en route and felt that if the mixture would have been richer the engine would have accelerated normally.

As the FAA filed it

ACFT LANDED DOWNWIND ON A DIRT STRIP AND A GUST OF WIND CAUGHT THE TAIL AND FLIPPED THE ACFT OVER. (.4)AS THE PILOT APPROACHED THE AGRICULTURAL APPLICATION AIRSTRIP, HE DECIDED THAT HE WOULD LAND DOWNWIND SO THAT HE WOULD END HIS LANDING ROLL NEAR THE EQUIPMENT THAT WOULD BE USED TO LOAD THE AIRCRAFT. AFTER THE AIRCRAFT TOUCHED DOWN, THE PILOT BECAME UNCOMFORTABLE WITH THE DOWNWIND LANDING, AND ELECTED TO MAKE A GO-AROUND. HE APPLIED POWER TWO SEPARATE TIMES DURING THE ATTEMPTED GO-AROUND, BUT BOTH TIMES THE ENGINE COUGHED AND SPUTTERED AND WOULD NOT ACCELERATE. THE PILOT THEREFORE DECIDED TO ABORT THE GO-AROUND, AND ATTEMPTED TO STOP THE AIRCRAFT IN THE REMAINING RUNWAY. ACCORDING TO THE PILOT, AS THE AIRCRAFT WAS SLOWING, THE TAILWIND PICKED UP THE AFT END OF THE AIRCRAFT AND CAUSED IT TO NOSE OVER. IN A POST- ACCIDENT TELEPHONE INTERVIEW, THE PILOT SAID THAT HE HAD FAILED TO READJUST THE ENGINE FUEL MIXTURE FROM ITS MORE-LEAN CRUISE SETTING PRIOR TO LANDING. HE FURTHER STATED THAT THE ENGINE HAD BEEN WORKING FINE, AND THAT HE FELT SURE THAT IF HE HAD ADJUSTED THE MIXTURE PRIOR TO LANDING THAT THE ENGINE WOULD HAVE ACCELERATED WH EN HE ADDED POWER FOR THE GO-AROUND. (-23)AIRPLANE WAS FLOWN FROM RIGBY IDAHO TO A DIRT STRIP 3 MILES NW OF IDAHO FALLS ID. ACCORDING TO THE PILOT, HE ELECTED TO LAND WITH A TAILWIND BACAUSE A LANDING IN THAT DIRECTION WOULD ALLOW HIM TO COME TO A STOP NEAR THE EQUIPMENT THAT WAS GOING TO BE USED TO LOAD CHEMICALS IN THE AIRPLANE. THE PILOT STATED HE BECAME UNCOMFORTABLE WITH THE DOWNWIND LANDING AND ELECTED TO GO-AROUND. WHEN HE APPLIED POWER A SECOND TIME THE ENGINE COUGHED AND FAILED TO ACCELERATE, THE PILOT RETARDED THE POWER AND ATTEMPTED TO COMPLETE THE LANDING. THE PILOT BROUGHT THE STICK TO FULL-AFT THE TAIL WHEEL SETTLED ONTO THE TERRAIN AS THE AIRPLANE SLOWED THE TAILWIND LIFTED THE TAIL AND NOSED OVER. THE PILOT STATED HE LEANED THE MIXTURE EN ROUTE AND FELT THAT IF THE MIXTURE WOULD HAVE BEEN RICHER THE ENGINE WOULD HAVE ACCELERATED NORMALLY.
