Auster 6 / Tugmaster / AOP.6

Auster A.61 Terrier

Auster T.7





In 1948 the RCAF first obtained the Auster Mk VI, an improved, post-war model with a DeHavilland Gypsy Major engine, more fuel capacity and a longer undercarriage. The first of the Auster VI's served with 444 (AOP) Squadron at the Joint Training School (JTS), Rivers, Manitoba. The RCAF retired the last of their Austers in 1958.


After taking the Auster AOP 6 and 7 from service, Beagle did buy them and refurbished them to civil use. They were sold to private customers as the A.61 Terrier (AOP 6) and A.113 Husky (AOP 7).

The Beagle Terrier 2 was the name given to the modified Auster AOP (Air Observation Post) 6, after the Auster Aircraft Company was sold. It was powered by a Gipsy Major 7 engine. First flight of a Terrier Series 2 was made on 25 April 1962. The type is a three-seat touring and training monoplane. A total of 380 of these aircraft were built between 1946 and 1953.

The 6A Tugmaster and Terrier 1 were also rebuilt Auster Mk 6, but to lower standards.

Later adopted as the Auster T.7
The AOP.6 was developed from the Mk 5 with a modified fuselage and increased all-up weight and powered by a Gipsy Major 7 engine. Equipped with all-metal auxiliary aerofoil flaps below and behind trailing edge, and wings strengthened to take two 52.25 litre fuel tanks, the pilot and observer seated in tandem. Lengthened landing gear struts allowed a larger airscrew. Production completed in 1949. The T.7 was a two-seat trainer which could be quickly converted to full AOP standard. Equipped with side-by-side seating with dual controls, a third seat could be fitted.
