In 1928 Avro came to an arrangement with Fokker to license production of its successful F.VIIB/3m for sale in the British Empire (except Canada). The Avro designation 618 Ten was adopted as the aircraft was capable of carrying two crew and eight passengers. After a modification of the centre motor mounting to accommodate British airworthiness requirements, the aircraft was first displayed at the 1929 Olympia Aero Show. The Avro 642 Eighteen used the same wing as the Ten but had a new fuselage for 16 passengers.

Two of this fleet were lost in accidents: Southern Cloud in the Toolong range of the Australian Alps on 21 March 1931 (the wreckage was not found until 1958) and Southern Sun in Malaya in November 1931, while attempting the first airmail flight to the United Kingdom. The airline folded and the remaining aircraft were sold.
Southern Moon was rebuilt in 1933 for long-range flights, fitted with 330 hp (250 kW) Wright Whirlwind radial engines and restyled as VH-UXX Faith in Australia. The last surviving 618 Ten in Australia, it evacuated many people from New Guinea in 1941. Another two 618 Ten aircraft were also sold to Australian companies. Three of the 619 Five aircraft went to two Australian airlines, as did (after commercial service in Britain) the sole 642/2m.
Britain and elsewhere
Four 618 Tens were delivered directly to British customers. Two went to Imperial Airways (April and June 1931) and were chartered to the Iraq Petroleum Transport Company before returning to Britain in 1933. One went to Midland & Scottish Air Ferries (May 1933) and at the end of 1931 one went to Indian State Airways for the use of the Viceroy of India. Two Tens went to the Egyptian Army air force in January 1932, one of them surviving to join Indian National Airways in September 1934. The last production Ten was delivered to the Royal Aircraft Establishment's Wireless and Equipment Flight in July 1936 with the RAF serial K2682. One of the 624 Sixes was used by A.S.T Ltd; the other two were eventually sold to the Chinese government.
Accidents and incidents
- On 30 December 1933, G-ABLU Apollo of Imperial Airways collided with a radio mast and crashed at Ruysselede, Belgium, killing all ten on board.
- Avro X, 'Southern Cloud', crashed whilst on route from Sydney to Melbourne on 21 March 1931, with two crew and eight passengers, but with no survivors. The wreckage was located by chance, off course and facing in the wrong direction, in October 1958 by Thomas Sonter, a NZ carpenter employed by the Snowy Mountains Scheme, whilst he as on a hike.
