Role Radio trainer/Communications aircraft
Manufacturer Percival Aircraft Limited
Designer Edgar Percival
First flight 8 October 1939
Retired 1955
Primary users RAF
Fleet Air Arm
Number built 1,143
Developed from Percival Vega Gull

The Percival Proctor was a British radio trainer and communications aircraft of the Second World War. The Proctor was a single-engine, low-wing monoplane with seating for three or four, depending on the model.

Design and development

The Proctor was developed from the Percival Vega Gull in response to Air Ministry Specification 20/38 for a radio trainer and communications aircraft. The prototype aircraft first flew on 8 October 1939 [1] and the type was put into production for the RAF and RN. The prototype was tested as an emergency bomber during 1940 but this idea was abandoned as the invasion threat receded. F. Hills & Sons of Trafford Park near Manchester built 812 Proctors of several marks between 1941 and 1945.[2]

Operational history

The Proctor was initially employed as a three-seat communications aircraft (Proctor I). This was followed by the Proctor II and Proctor III three-seat radio trainers.

In 1941, the Air Ministry issued Specification T.9/41 for a four-seat radio trainer. The P.31 - originally known as the "Preceptor" but finally redesignated the Proctor IV - was developed for this requirement with an enlarged fuselage. One Proctor IV was fitted with a 250 hp (157 kW) Gipsy Queen engine. This was used as a personal transport by AVM Sir Ralph Sorley but production models retained the 210 hp (157 kW) motor of earlier marks.

At the end of the war, many Proctors of the early marks were sold onto the civil market. The Mk IV soldiered on with the RAF until the last was withdrawn in 1955.

In 1945, a civil model derived from the Proctor IV was put into production for private owner, business and light charter use as the Proctor 5. The RAF purchased four of these for use by air attachés.

The final model of the line was the solitary Proctor 6 floatplane sold to the Hudson's Bay Company in 1946.

Notable Owners

Survivors

Flying

Proctor Mk III G-ALJF and Proctor Mk IV G-ANXR (RAF number RM221) are both airworthy and based at Biggin Hill.

Under restoration

Proctor III LZ766 at the Imperial War Museum, Duxford, Proctor IV NP294 at the Lincolnshire Aviation Heritage Centre, East Kirkby, G-AHTE at Clacton and Air Atlantique Classic Flight's G-AKIU are under restoration.

Proctor Mk III G-AOGE has been at Biggin Hill for at least 20 years. The airframe has been completely restored over this time with much new wood and modern glue, but it has lain in the corner of one of the hangers for the last five-six years awaiting the finances to restore its engine.

On display

Proctor III Z7197 is on display at RAF Museum, Hendon. Another Mark III is on show at the RAAFAWA Museum, Bullcreek, near Perth, Western Australia.
