NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot took off in the tailwheel-equipped airplane and noted that the wind velocity was higher than expected, so he elected to return to the departure strip. The pilot reported that the wind produced a 12- to 15-mph tailwind for landing and that the combined effects of the tailwind and excessive airspeed caused the airplaneā€™s tail to immediately begin to rise after touchdown. After rolling about 20 feet, the airplane nosed over and came to rest inverted. The pilot said that the accident could have been prevented if he had flown in less windy conditions and that he should have executed a go-around.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's decision to land with a high tailwind, which resulted in a nose-over.
