On June 23, 2006, about 0905 eastern daylight time, a wheel-equipped Rockwell 112TCA airplane, N1052D, sustained substantial damage when it ditched in the ocean waters of Sarasota Bay during a landing approach to the Sarasota/Bradenton International Airport, Sarasota, Florida. The airplane was being operated as a visual flight rules (VFR) cross-country personal flight under Title 14, CFR Part 91, when the accident occurred. The airplane was operated by the pilot. The private certificated pilot was not injured, and the sole passenger received minor injuries. Visual meteorological conditions prevailed. The flight originated at the Sarasota/Bradenton Airport about 0858, and was en route to Venice, Florida. No flight plan was filed. During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC), on June 23, a Federal Aviation Administration (FAA) inspector, Tampa Flight Standards District Office (FSDO), Tampa, Florida, reported that after departing the Sarasota Airport, the pilot radioed that he needed to return to the airport because he was low on fuel. The airplane was cleared to land on runway 04 at Sarasota, but ditched in Sarasota Bay, about 50 yards from the beach. The airplane received structural damage to the fuselage and wings. During a telephone conversation with the NTSB IIC on June 23, the pilot reported that after departure he climbed the airplane to 1,600 feet mean sea level (msl). After contacting Tampa Approach Control, he made a left turn toward Venice. He said the engine began to run rough and lose power, and he requested a return to the airport. During the final approach to runway 04, the airplane could not maintain altitude, and he ditched the airplane in Sarasota Bay with the landing gear up. The pilot said the airplane had at least 10 gallons of fuel at departure, and his comment to the air traffic control tower was because he was having some type of fuel problem. He said he did not think the engine actually quit completely. In the Pilot/Operator Aircraft Accident Report (NTSB Form 6120.1/2) submitted by the pilot, the pilot indicated that he preflighted the airplane and sumped the fuel tanks. He said he found some debris, but continued to sump the tanks until he obtained clean, debris-free fuel. He looked in the fuel tanks and confirmed the presence of fuel. He rocked the wings and heard a sloshing sound from each tank. The pilot reported that the fuel totalizer indicated 10 gallons of fuel in the tanks. After making a left turn, the engine began to run rough, and he requested a return to Sarasota Airport. He said the airplane could not maintain altitude, and he was unable to reach the airport. He ditched the airplane in Sarasota Bay, and the airplane settled to the bottom in about 3 feet of water, and about 50 yards from shore. The pilot said that the engine continued to run roughly during the emergency descent, and was running upon contact with the water. The pilot indicated that he believed the cause of accident was debris in the fuel tank, picked up during the turn. He also said that it was "entirely possible that this circumstance could have been avoided if there was a greater quantity of fuel in the tank." After the airplane was recovered to the owner's hanger, an FAA inspector examined the airplane on July 5, 2006. The airplane remained positioned on its belly with the landing gear retracted. The inspector was unable to reach the airframe gascolator. Visual examination of the interior of the fuel tanks revealed a small amount of fuel that sloshed at the bottom of the tanks. He pulled the fuel sump drain, but no fuel discharge was observed. The inspector indicated that his review of air traffic control tapes from Sarasota Air Traffic Control revealed that the pilot requested to land due to fuel starvation. The inspector also reported that in his conversations with the pilot, the pilot told him that the estimate of fuel in the tanks was based on the fuel totalizer indication. The pilot did not attempt to measure the fuel, but opened the fuel caps to see some fuel sloshing in the tanks.
