HISTORY of FLIGHT On Monday, October 25, 1993, at about 2045 eastern daylight time, a Piper PA-28-180, N16493, piloted by Mr. Rudy Fanari, collided with water during a forced landing near Centerville, Maryland. The airplane was destroyed, and the pilot received minor injuries. Visual meteorological conditions prevailed at the time, and no flight plan had been filed. The flight was being conducted under 14 CFR 91. The airplane's engine lost power for unknown reasons, and the pilot made a forced landing in the Chester River, 200 yards off Spanish Point, in 20 to 30 feet of water. According to the pilot's statement on the NTSB form 6120.1/2, after approximately one and a half hours of flight time, he switched fuel tanks from the right tank to the left tank. After switching tanks the engine started to run rough for approximately 2 minutes, and the pilot could not maintain altitude. The pilot said he checked gauges,switches and fuel, but could not determine the problem. The engine continued to lose power until the airplane impacted the water. Several witness standing on the shore near the crash site heard: ...a loud roaring noise...over the river and no lights were visible...we all witnessed the sound, but could not determine if the noise was a boat or airplane. The object seemed out of control. ADDITIONAL INFORMATION The airplane was not recovered from the water and the reason for the loss of engine power was not determined.
