N3228BPiper PA-22-135

The pilot was flying to the destination airport where a mechanic was scheduled to perform an annual inspection of the airplane (that was about to be overdue). While enroute, a storm had arrived over the destination airport, so the pilot diverted to what he thought was a private airstrip. As soon as the airplane touched down, he realized that it was not a maintained airstrip. The pilot waited for the storm to pass, then elected to resume the flight and attempted to take off. During the takeoff roll, he was forced to abort because of the wet and rough ground condition. He attempted a second takeoff from another part of the field that appeared smoother, but during the second takeoff attempt, about 1/3 of the way into the takeoff roll, the terrain got progressively wetter and muddier. The airplane began to skid left and right, and the pilot was unable to maintain directional control. The left wing subsequently struck the ground which resulted in the airplane nosing over and coming to rest inverted. The pilot received minor injuries, and the airplane’s wings, rudder and vertical stabilizer were substantially damaged. The pilot reported there were no preimpact mechanical malfunctions or failures with the airframe or the engine that would have precluded normal operation. He further stated that in retrospect, he had a “get-there-it is mentality” because of the airplane’s impending inspection deadline.
