On June 29, 2001, at 1215 mountain standard time, a Cessna 182P, N7336Q, veered off the runway and collided with a ditch while landing at Mesa, Arizona. The airplane sustained substantial damage and the certificated private pilot was not injured. Structures, Inc., was operating the airplane as a personal flight under the provisions of 14 CFR Part 91 at the time of the accident. The local flight had originated from Falcon Field, Mesa, about 1210. Visual meteorological conditions prevailed at the time, and no flight plan had been filed. The pilot reported that he landed on runway 22R. Between the landing and takeoff of a touch-and-go landing, he retracted the flaps, applied full throttle, and turned off the carburetor heat. He did not verify that the trim was in the correct takeoff position. After liftoff, the airplane lost directional control, landed to the left of the runway, crossed back over the runway, and came to rest on the right side of the runway. The pilot stated the winds were reported as 40 degrees to the right of the runway heading at 11 knots, and there were no gusts. The closest weather reporting station was Phoenix Sky Harbor airport (PHX) about 17 statute miles east of Mesa airport, and at 1156, was reporting the winds to be 250 at 13 knots.
