Percival Provost
The Percival P.56 Provost was a British ab initio trainer for the Royal Air Force in the 1950s, replacing the Percival Prentice. It was a low-wing, monoplane with a fixed, tailwheel, undercarriage. Seating was side-by-side. After a lengthy service career, the design was adapted for a turbojet.

Design and development
The Provost was designed to Air Ministry specification T.16/48 for a basic trainer to replace the Percival Prentice. The British Air Ministry further issued Operational Requirement 257 (O.R.257), defining the need for a new, higher performance, piston-engine trainer.[1] The prototype first flew on 24 February 1950, powered by an Armstrong Siddeley Cheetah 18 engine, which was replaced by an Alvis Leonides engine on later prototypes and production aircraft[2]
After evaluation against the Handley Page H.P.R 2, the Provost was selected for production, with an initial order being placed in 1951. Production ended in 1956 when 461 aircraft had been completed. The Percival Provost eventually formed the basis for the Jet Provost trainer which replaced it in RAF service.
Operational history
The Provost entered service with the RAF in 1953. It had more than twice the power of its predecessor, the Prentice, with higher performance and manoeuvrability. The aircraft served with the RAF until the early 1960s, when it was replaced by the Jet Provost. A few Provosts continued in service until the last example was retired in 1969. Several retired airframes were renumbered with maintenance serials and used for training of airframe and engine tradesmen. At least five Percival Provost have survived as civilian aircraft.
