Visual meteorological conditions prevailed at the time and no flight plan was filed for the 14 CFR Part 91 personal flight. The airplane was substantially damaged and the private-rated pilot and one passenger were not injured. The flight originated from the Albert Whitted Airport, St. Petersburg, Florida, approximately 36 minutes earlier. The pilot stated that after takeoff he flew to the Clearwater airport where he performed one full-stop landing and taxied back then departed to return to the St. Petersburg airport where he performed one touch-and-go landing followed by a full-stop landing.
