Analysis

The plt departed VFR on a personal flt along the shoreline. No flt plan was filed. The plt/pax initiated a climb and the eng started to backfire. The plt took control of the airplane, applied full throttle, obtained best glide airspeed and initiated a forced landing on the beach. However, the landing was diverted to the ocean due to personnel on the beach. Witnesses stated they observed the airplane in maneuvers described as chandelles with sharp power reduction and 1/2 mile glide. Examination of the engine revealed no evidence of precrash failure or malfunction. A review of icing probability charts indicated serious icing at glide power based on weather conditions at the time of the accident.
