Probable cause
The pilot's incorrect elevator control while taxiing with a quartering tailwind. Contributing to the incident was the tailwind condition.
Sequence of events

Analysis
While taxiing at a brisk walk with a quartering right tailwind, the tail raised. The pilot applied power and aft elevator, then the airplane nosed over.
