Fairey IIIF G-AASK, fitted with a Jaguar VIC geared radial, was modified for the Air Survey Company late in 1929 and was one of two flown to undertake aerial survey work in the Sudan.
Having completed his demonstrations, McMullin flew G-AABY back to Croy- don via Uskub (Skopje), Belgrade, Vienna, Nuremberg and Cologne, completing the trip in 14 hours 35 minutes. In Yugoslavia he gave a demonstration at Novi Said military aerodrome, and then flew Prince Paul (the future King Paul of the Hellenes) to England to see the Schneider Trophy contest. On return he reported: 'Throughout the trip we had not the slightest trouble with either the aircraft or the Napier Lion XI engine, and although it entailed a lot of hard work, Baker and myself enjoyed ourselves heartily'.
Later G-AABY was fitted with an Armstrong Siddeley Panther IIA radial, deliv- ered to East India Docks by Lep Transport on 26 March 1931, and shipped out to Arnhold & Co of Shanghai for demonstrations, but it crashed on its first attempted take-off in April and suffered damage that necessitated its return to England for repairs, these being carried out at RAF North Weald, Essex, in 1934. At this time the aircraft was entered in the handicap section of the October 1934 MacRobertson Trophy Race from England to Australia. Piloted by Flying Officer C. G. Davies, and with Lieutenant Commander C. N. Hill as navigator, it flew as No 15 and was named Time and Chance. As a result of delays en route, notably with aileron problems at Nicosia, Cyprus, the aircraft was retired from the race and did not reach Melbourne, the ultimate destination, until 23 November, well after the time limit set for completion of the flight.
In Australia Davies flew G-AABY on charter work for Austral Air Services of Queensland. On 13 March 1935 it was given the Australian registration VH-UTT, and on the 20th it was registered to Major E. G. Clark, trading as Austral Air Services. On 10 April it was sold to long-distance flyer Ray Parer of Wau, New Guinea. On 12 March 1936 its Certificate of Registration lapsed and it was struck off the register, but its C of R was renewed on 25 August the same year. When the C of R lapsed again a year later, on 24 August 1937, VH-UTT was broken up and struck off the register.
Two Jaguar-engined IIIFS, G-AASK (F1272, Jaguar VIC/geared) and G-AATT (F1315, Jaguar VI), were specially modified late in 1929 to work with Air Survey Ltd in the Sudan, the company having recently become a Fairey subsidiary. The first was delivered to Air Survey at Croydon on 1 January 1930, the other follow- ing on 6 February that year. After leaving for Juba on 23 January 1930, G-AASK remained in service until the end of 1934. The working life of its sister aircraft, G-AATT, which left Britain on 22 February 1930, was terminated when it was destroyed in a crash that October.
