The pilot reported that while landing his tailwheel-equipped airplane to runway 25 a strong quartering tailwind caused the airplane to swerve to the left. In an attempt to arrest the swerve, the pilot applied full right rudder and right brake. As the airplane responded back to the right, the left wing impacted a fence post. Subsequently, the airplane nosed over and came to rest in an inverted position. The airplane's wing strut was bent during the mishap. Approximately 23 minutes after the accident, a weather reporting station located 17 miles northeast of the accident site, reported winds from 70 degrees at 16 knots gusting to 24 knots. The pilot did not report any pre-impact mechanical malfunction or failure with the airplane.
