According to the pilot, he was conducting touch-and-go landings at his home airport. He stated that the flight controls felt "a little mushy" during approach for the first landing, and that "the airplane was more nose high than it should have been." He also stated that the airplane had a "high descent rate" and landed "flat with too much force." Post-accident inspection by a Federal Aviation Administration inspector revealed substantial damage to the right wing spar. The pilot further stated that there were no mechanical malfunctions or anomalies of the airplane, and that he "should have added power" during the landing approach.
