Design and development
The P.9 was designed as a larger version of the companies P.6 single-engined biplane design, it was 6 ft longer with a 2 ft 6in increase in wing span. It had the same 90 hp (67 kW) RAF 1 V-8 engine as the P.6 but had an increased fuel capacity. The first order was from A.L Long for use on a sheep station in Australia and the first aircraft was delivered to Australia and it was soon used on newspaper delivery flights. On 17 December 1919 it made the first flight across the Bass Strait between Tasmania and the mainland.
With the success of the first aircraft in Australia, minor changes were made to production aircraft, including a compartment behind the cockpit to carry two specially built suitcase. Although the aircraft was for sale at a modest £700, mainly due to the use of an old but standard engine, it failed to compete with war-surplus sales of converted military aircraft and only eight aircraft were built in total, including a further three to Australia.
