Written off 26/06/1956: Ditched into the North Sea off the beach at two miles north east of North Coates, Lincolnshire, after the engine lost power due to a gearbox failure during a winching exercise. The aircraft ditched on it's side onto a sand bar in shallow water. It was recovered at low tide, but deemed a write-off, due to prolonged immersion in salt water.
