At approximately 1130 Mountain time, the airplane was substantially damaged when it impacted terrain and a fence following a loss of control while performing touch and go maneuvers at Jeffco Airport, Broomfield, Colo The Private pilot, who was the sole occupant, was not injured. Visual conditions prevailed. The pilot later stated he was performing touch-and-go landings to Runway 29L. On the approach, the pilot configured and stabilized the airplane for landing and all seemed to be in order. After crossing the runway threshold, the pilot felt the speed and sink rate were too fast. The airplane touched down and bounced twice. At that point, the pilot added power to abort the landing. The airplane drifted to the left and began to porpoise. Subsequently, the airplane skipped across the grass adjacent to the runway, went down an embankment, and came to rest upright against a chain-linked fence. The pilot did not have a complex airplane endorsement in his logbook.
