Development

edit

Designed by Desmond Norman when with Britten-Norman, the BN-3 Nymph was an all-metal high-wing braced monoplane powered by a 115 hp Lycoming O-235 engine. It was designed to allow it to be assembled in under-developed countries which would build the aircraft under a technology transfer scheme.[2]

With the demise of the original Britten-Norman company, Norman took the design with him to his new company NDN Aircraft. NDN planned to build and sell the Nymph with a lengthened cabin as the NAC-1 Freelance. The Nymph was reworked as the prototype Freelance and first flew in that configuration on 29 September 1984.[1] In 1985 NDN Aircraft was renamed the Norman Aircraft Company (NAC) and components and fuselage sections for six aircraft were built. Following the failure of the company to win a military order with the NDN Firecracker military trainer the company was closed down.
