Certification and production plans for Chichester-Miles Consultants’ (CMC) Leopard Six twinjet have been targeted, along with a sales launch, for the end of 2004. The company reports that the project requires an investment of $90 million.

Over the past several years, CMC has been developing the concept of the 500 mph four-seat Leopard 4 twinjet, the second prototype of which has been engaged in flight testing and research since 1997.

The structure and systems of the Leopard Six follow the company’s experience with its smaller forerunner. Like the earlier aircraft, CMC says, it is an all-composite structure with systems following the principles of simplicity and maintainability.

The Leopard Six is to be introduced into the $1-3 million light jet market. According to CMC, it will offer a combination of speed, altitude and useful range with roominess and comfort for its occupants.

Says Ian Chichester-Miles, ceo and chairman of CMC: “More than any other element in the make-up of the Leopard Six, the Williams International FJ33-1 turbofan engines define the product, its performance, its market appeal, and its availability.

“It is the engine which makes the aircraft possible technically. The early availability of the FJ33-1, with engine type certification by mid-2002, gives generous margins for the perfection of the airframe and realisation of the production launch.”
