The pilot was experienced in the accident aircraft and familiar with the airport. The aircraft's weight at the time of the accident was estimated to be between 3,350 to 3,800 pounds (the latter weight being maximum gross takeoff weight). No evidence of control or power plant malfunction was found. The flaps were fully extended as were the landing gear. The fire damaged remains of an assortment of tools, construction material, personal effects as well as a cooler of beer, all totaled to weigh an estimated 200 pounds minimally, were found in the cabin area. The pilot-in-command's toxicology was negative, however the rear left seat passenger screened positive for ethanol (0.14 gm/dl blood (heart) and 0.15 gm/dl vitreous).
