Beagle-Auster E3 A.O.P. Mk.11

09/30/2016. Remarks by Johan Visschedijk: "Destined for the British AAC this aircraft was ordered from Auster Aircraft Ltd. as a B5 A.O.P. Mk.9 under serial XP254 (c/n B5/10/162) in 1959. While XP254 was under construction, Auster Aircraft became Beagle-Auster Aircraft Ltd. (Beagle = British Executive and General Aviation Ltd.) on September 7, 1960, and in Spring 1961 the aircraft was selected for the prototype Beagle-Auster A.O.P. Mk.11.

Under the company designation A.115 (which later changed to E3), design work on the A.O.P. Mk.11 began in April 1961 and it was almost identical to the A.O.P. Mk.9. Main difference was the 260 hp Continental engine replacing the 173 hp Cirrus, furthermore a large dorsal fin was added and initially it had landing gear strut covers and wheel spats. Still allotted the military serial XP254, but with the new c/n B.701, the aircraft was first flown on August 18, 1961. The aircraft participated in the SBAC Display at Farnborough in September 1961.

XP254 was never delivered to the AAC and in 1962 Beagle Aircraft (by then 'Auster' had been dropped from the company name) reserved the 'Class B' marking G-25-12. However, this was not taken up, instead the aircraft was registered G-ASCC on July 23, 1962 and on August 29 a CofA was issued. Despite extensive demonstration flying the type was not sold and eight years later, July 31, 1970 the registration was cancelled. It came back on the register on January 18, 1971 and since it had nine successive owners and is still registered as of this day.
