On May 30, 2006, at 1630 mountain standard time, a Waco Classic Aircraft Corp. YMF 5C airplane, N515TT, ground looped while landing on runway 3 at the Holbrook Municipal Airport (P14) Holbrook, Arizona. The airplane was registered to the private pilot, who operated the airplane under the provisions of 14 CFR Part 91 as a personal flight. The airplane sustained substantial damage. The pilot was not injured. Visual meteorological conditions prevailed and a flight plan had not been filed for the cross-country flight that originated from Kingman, Arizona, at 1500. According to the pilot's written statement, he had established the tail wheel equipped biplane at 75 knots for the wheel landing. Upon touchdown a gust of wind "blew the tail to the right, initiating a turn to the left." The right lower wing contacted the pavement, and the airplane eventually departed the left side of the runway into sandy soil. The right main landing gear collapsed and the airplane nosed down coming to rest on the propeller, left wing tips, and left main landing gear. The airplane sustained substantial damage to the landing gear, wings, and fuselage. The pilot reported the wind as variable but predominantly from 120 degrees at 9 knots.
