History

The ATL -90 Accountant was of Aviation Traders Ltd.. developed as a twin-engined turboprop passenger aircraft, and was by the will of company executives Freddie Laker as the successor of the Douglas DC-3 provided. His first designs for a successor to the Dakota went back to the year 1945 and with the ATL - 90 should now as before with the DC-3 aircraft arise that should be sold all over the world. The ATL -90 was designed as a low-wing aircraft and conceptually something like a slightly smaller variant of the excellent proven equipped with four turboprop engines of the type Rolls-Royce Dart passenger aircraft Vickers Viscount for short and medium distances. To save time and money in the development Laker took the bow and cockpit section of the Vickers Viscount, which is why the machine quite certain similarities with the latter machine had up on the twinengines, with the tail distinctly different turn. Laker expected due to the visual similarity not only to the Vickers Viscount some chances on the market and wanted to go into series production of certain machines, the market area covering roughly the Fokker F-27. The only prototype first flew on 9 July 1957 with the registration G- ATEL. There were three prototypes provided, of which only one was completed and flown. It could be won no customer for the project despite undeniable qualities and some international interest, as the market with the already successful patterns Avro 748, Handley Page Dart Herald and Fokker F-27 Friendship was already saturated. The program was therefore finally ceased in 1958 and scrapped the prototype in February 1960.
