Percival Provost
The Percival P.56 Provost was a British ab initio trainer that was developed for the Royal Air Force in the 1950s as a replacement for the Percival Prentice. It was a low-wing monoplane with a fixed, tailwheel undercarriage and like the Prentice had a side-by-side seating arrangement. The Provost has the distinction of being the last piston-engine basic trainer aircraft to be operated by the RAF.
The Provost was later adapted to make use of a turbojet engine, producing the BAC Jet Provost. The type was withdrawn in the 1960s, in favour of its jet-powered successor.
Development
The Provost design is attributed to the Polish-born Aeronautical Engineer, Henry Millicer. Millicer later moved to Australia where he also designed the award winning Victa Airtourer light aircraft. The Provost was designed to Air Ministry specification T.16/48 for a single-engined basic trainer aircraft to meet Operational Requirement 257 for a Percival Prentice replacement. The specification was issued on 11 September 1948 and the ministry received over 30 proposals for consideration. Two designs were chosen for prototype construction, the Handley Page H.P.R 2 and the Percival P.56. Percival was given a contract dated 13 January 1950 to build two Cheetah powered prototypes. The company also built a third prototype with an Alvis Leonides Mk 25 engine.
