The pilot said the wind was 'steady at 14 mph, gusting to 24 mph,' between 240 and 260 degrees, as he attempted to make a crosswind wheel landing on runway 20. When the airplane touched down, the left wheel 'skidded' when left brake was applied. The airplane ground looped and departed the right side of the runway, incurring substantial damage to the left wing. The airplane was FAA certificated under Type Certificate 3A24. No maximum or demonstrated crosswind component is listed in the Pilot's Operating Handbook.
