Classic Aviation Designs Ltd

The concept of Classic Aviation Designs Limited was conceived in 2004, and the company was incorporated on 31 Janauary 2012. Originally the concept was to reintroduce affordable aviation at grassroot levels to new and experienced builders of aircraft.

Designing and building of the Adventurer CA18 was as a sideline. Part of the inspiration behind the Adventurer CA18 was to attract a new generation to sport flying and aviation related careers.

With the assistance of some key people such as Sid Siddiqi an ex Nasa engineer and retiree, CADL was able to present the concept of the Clubflyer Education Programme (CEP) at the 2011 and 2012 Oshkosh Trade Show. This concept was universally agreed, by all who attended the talks or from those spoken to privately at the event, that the programme had good merit to help revitalise the aging issues of aviation.

From the initial concept it was identified that private builders would also be interested in building the aircraft. CADL revised its initial education project to also incorporate a private builders programme.

Clark Aircraft Corp

USA
Subsidiary of Fairchild formed February 10,1938 under presidency of Harold Clark. He developed Duramold process of constructing fuselages in molded halves of a plastic compound material, joined along top and bottom centerlines. Production of prototype Clark F-46A three/four-seat monoplane followed, using this technique, at Fairchild’s Hagerstown, Maryland factory.

Clancey Brothers

Australia
Jack Clancy was the youngest of the three Clancy brothers who burst into prominence in 1931 with the Skybaby, a single-seat light aircraft they had designed and built themselves. In the era of the Depression, it was the highly successful Skybaby which led them into aviation and an escape from infrequent and poorly paid jobs.
Bill Clancy was the talented designer of the Skybaby. He went on to a career as a noted engineer with the railways. During World War Two he played an important role in the Beaufort construction program.
Allan Clancy became a popular and respected flying instructor with the Kingsford Smith Flying School and later served in the RAAF. After the war he worked for Butler Air Transport but his flying career ended following an unfortunate accident in a DCA aircraft in 1951.

Civil Aviation Department of India

Technical Centre, Civil Aviation Department
Civil Aviation Directorate,
Talkatora Road,
New Delhi

Seven types of glider have been developed at this Technical Centre, which is the research and development establishment of the Indian Civil Aviation Department, since 1950.
Some are based on well-known designs such as the Grunau Baby and Olympia; but the three latest types, the Ashvini, Rohini and Bharani, are of original design and are intended to use indigenous materials wherever possible. The Technical Centre does not undertake quantitymanufacture of sailplanes, but supplies sets of drawings to private concerns such as Aeronautical Services Ltd, which is producing the Ashvini and Rohini.

The RG-1 Rohini-1 side-by-side two-seater trainer was the first type designed at the Technical Centre of India’s Civil Aviation Department to go into production in more than small quantities. Starting with an open-cockpit primary type glider first flown in November 1950, the Technical Centre built two Model PT-G open cockpit primary single-seaters based on the ESG design, six Model IT-G intermediate trainers based on the Grunau Baby, two Model AS-1 high performance sailplanes based on the Olympia and five Ashvini tandem two-seater trainers resembling the DPS Kranich; 11 more Ashvinis were built by Aeronautical Services Ltd of Calcutta.
