Factual narrative

On December 17, 2003, about 1400 mountain standard time, a Piper PA-11, N5516H, came to rest inverted after attempting to land in a soft dirt field in Gilbert, Arizona. The pilot/owner was operating the airplane under the provisions of 14 CFR Part 91. The private pilot, the sole occupant, was not injured; the airplane sustained substantial damage.

Upon touchdown, the airplane's main landing gear sunk into the soft terrain. The airplane nosed over and came to rest inverted. The damage incurred from the accident included a bent wing strut, a bent rudder, and several holes wing skin.
