The pilot reported that he began the takeoff roll in the tailwheel airplane with a left quartering headwind. He stated that during the takeoff roll a wind gust caused the airplane to swerve. He attempted to abort the takeoff and the airplane ground looped. During the event, the right main landing gear collapsed and the wingtip struck the runway damaging the wing structure. A weather reporting station located 18 nautical miles south of the accident site recorded the wind 7 minutes before the reported accident time as 190 degrees at 11 knots gusting to 18 knots. Fifty-three minutes after the accident time the same weather station recorded the wind speed as 7 knots gusting to 14 knots and direction as variable between 130 degrees and 200 degrees. Examination of the airplane after the accident revealed a failure of the left steering spring chain link. It could not be determined if the chain link failure occurred prior to or during the accident sequence.
