Aviation Traders ATL.90 Accountant

The Accountant (named for its supposed good economics) was another attempt to replace the DC-3 in the postwar airlines and air forces. Aviation Traders, a small British company mainly involved in converting passenger aircraft to freighters, decided to enter the market in 1952 with a modern-technology turboprop.

The company changed its mind a lot over construction methods and configuration and promised that the production aircraft would differ greatly from the prototype, perhaps not the wisest marketing strategy. If the company had won big orders they had no suitable facilities in which to produce them. Eventually the company's own accountants were heeded and it was realized that the sensible decision was to not proceed further. The ATL-90 was stored in 1958 after a very short flying career, and broken up in 1960.

Jim Winchester "The World's Worst Aircraft", 2005


The Rolls-Royce Dart turboprop was the engine of choice of the day, powering the Fokker Friendship and Handley Page Dart Herald, both of which were built by large manufacturers on the basis of sound economics.

Standard accommodation would be 28 passengers, although a 42-seat ATL-91 version was planned, as was a 14-seat executive transport.

The unusual shape of the forward fuselage was due to the swing nose arrangement proposed for production freighter aircraft. The passenger version would have had a different shape.

Saw it land once from warmers bridge. Was (still am) an avid spotter in those days. Still prefer a DC3.

Iam surprise of the similarity of this plane with the Grumman Gulfstream I (G-I), which was a very successful executive plane for corporations. It seems to me that "the accountant" was not not successful because their designers were thinking in it as a commercial airline plane. However, Leroy Grumman found the right market for his G-I.

I remember being in the Air Training Corp and we were taken to look at this new plane being built at the airport. Being fourteen or so at the time I can not remember much except looking up at it surrounded by scaffolding. I don't remember seeing it fly but I have been given some photos taken when it first flew.

By the time Freddie Laker (who ran Aviation Traders) realised that he was on an uphill struggle to sell this machine for about 20 times the cost of DC3s at the time, a great deal of money was thrown away. I saw it looking forlorn and abandoned at Southend Airport in 1959 or so By then, Laker had bought the entire RAF fleet of Percival Prentices, all but filling the grass areas of Southend and was converting them to civil use.

There is a clip of this aircarft taxying at the Farnbourough airshow in the late 1950's. The clip was part of the British newsreel footage. A compilation of these clips are availabe on video from the 'DD' video commpany, London. Well worth a look for all the wonderful Britsh aircraft of the era - many of which were the ahead of any others in the world at this time.
