Probable cause
That the pilot failed to properly compensate of the existing quartering tailwind, improperly using the flight controls and brakes.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot had made one landing and takeoff on the 4800 ft long and 100 ft wide runway. When on the downwind leg the surface winds shifted to a quartering tailwind. The local controller did not advise the pilot of the wind change and cleared the flight to land. Upon touch down the airplane ground looped and nosed over. The pilot improperly used the flight controls and brakes to arrest the ground loop. Examination of the brakes and tailwheel assembly disclosed no evidence of any malfunctions or failures.
