The Auster A.O.P. 6 is a light observation aircraft that was developed from a line of similar machines by the Taylorcraft/Auster company. It was an easily maintained aircraft that could operate from short improvised landing strips in forward battle areas. The Canadian government received 36 Auster 6s in 1948, and 6 Auster 7s in 1951. These aircraft were gradually taken out of service as deliveries of a new machine, the Cessna L-19 Bird Dog, began in 1954. The last Auster was struck off strength in May 1958.
The Museum Auster was taken on strength by the RCAF in 1948. In 1957, the Auster was sold for civilian use, and after passing through the hands of several Canadian owners, was purchased by the Canadian War Museum in 1965. This aircraft was restored by No. 6 Repair Depot, RCAF.
The Museum aircraft is finished in the colours of the RAF Auster in which a Canadian, Capt. P.J.A. Tees, won a Distinguished Flying Cross in Korea.
