The Auster AOP.9 was designed as a successor to the Auster AOP.6. Like its predecessor, it was a braced high-wing single engined monoplane with a fixed tailwheel undercarriage. Although having the same general appearance, the AOP.9 was a new design, with larger wing area and a more powerful engine.
The wing and tail were metal-skinned, but the fuselage and ailerons were fabric-covered. The fin and rudder assembly were more angular in the new aircraft with a noticeable dorsal fillet.
A combination of the more powerful 180 hp (134 kW) Blackburn Cirrus Bombardier engine, larger wings and large flaps gave it an improved take-off and landing performance compared with the AOP.6. It could operate from ploughed fields and muddy surfaces using low pressure tyres and strengthened undercarriage.
