The Coupé-Aviation JC-01 is the first of a series of very similar designs of two seat, single engine sports aircraft, amateur built from plans in France from 1976.

The different models are chiefly distinguished by engine choice, though undercarriage configurations vary and there are slight alterations to the vertical surfaces.

The empennage of the J-2 is conventional and cantilever, with the horizontal tail mounted on top of the fuselage; both fin and rudder are swept, the latter only slightly.

A 67 kW (90 hp) Continental C90 flat four engine in the nose drives a two-blade, fixed pitch propeller.

Some builders included their own name and initials in the aircraft description, for example the Dessevres-Coupé JCD 01 and the Coupé-Brault JCFB 01.
