Edgar Percival Aircraft Limited was a British aircraft manufacturer from 1954 to 1958. The company was based at Stapleford Aerodrome, England.
In 1954, Edgar Percival formed Edgar Percival Aircraft Limited a few years after his original company the Percival Aircraft Company had become part of the Hunting Group. His first new design was Edgar Percival E.P.9 which was a utility aircraft designed for agricultural use.
In 1958 Samlesbury Engineering Ltd Limited acquired rights to the design and the company formed a subsidiary named the Lancashire Aircraft Company Limited.
