On March 5, 2006, about 1400 pacific standard time, a wheel equipped Piper PA-24 airplane, N6094P, sustained substantial damage while landing at the Gillespie Field Airport, El Cajon, California. The airplane was being operated as a visual flight rules (VFR) local area flight under Title 14, CFR Part 91 when the accident occurred. The solo student pilot was not injured. Visual meteorological conditions prevailed. No flight plan was filed. The flight originated at the Gillespie Field Airport about 1355. During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC), on March 5, the student pilot reported that he was practicing touch-and-go landings on runway 27R, a dry paved runway. He said that after landing, as he applied full engine power for takeoff, the airplane veered to the left and continued off the left side of the runway. He aborted the takeoff, but the airplane's right main wheel struck a sign post and the right main landing gear collapsed. The airplane's right wing struck the ground, and sustained substantial damage. The student pilot noted that there were no preaccident mechanical anomalies with the airplane.
