The CMC Leopard is a light personal business jet aircraft under development in the United Kingdom since the 1980s.


The Leopard is a low-wing cantilever monoplane of composite construction with all-swept flying surfaces and jet fighter-like styling other than the podded engines on either side of the aft fuselage. The entire canopy hinges forward to allow access to the four seats. A mockup was completed in 1982, leading to a prototype (registration G-BKRL) built by the Designability company. The prototype first flew late in 1988. Development suffered a major setback when the engine manufacturer (Noel Penny Turbines) ceased business, leading to the grounding of the prototype. A second, refined prototype (registration G-BRNM) was then constructed to use Williams International turbofans. This aircraft also incorporated a pressurised cabin, revised undercarriage, and a generally strengthened airframe. This second prototype was unveiled at the 1996 Farnborough International Airshow and first flew on 9 April 1997.

As of 2002, development was confined to these two aircraft, by then retrospectively redesignated Leopard FOUR to distinguish them from a proposed six-seat variant, the Leopard SIX. Until 2008 the two prototype Leopards (001 & 002) were on display at The Bournemouth Museum. But with the museum closing in early 2008, 002 is being moved to Coventry Air Museum. 001 is not flyable and is wanted by Airborne Composites as a gate guard.
