The present invention relates to a ducting for a fuel pipeline of an aircraft or spacecraft, in particular designed to be mounted in each of the wings of an aircraft, an aircraft wing incorporating this ducting and a method for producing same. This ducting comprises at least one multilayer pipe (1) having two respectively inner (2) and outer (3) layers made of a composite plastic material that is leakproof and chemically resistant to the fuel and that is reinforced by electrically conductive reinforcing means, these layers being separated by an intermediate layer (4), notably capable of stiffening the pipe when flexed and/or to insulate it electrically. According to the invention, each of the inner and outer layers has at least one winding with contiguous turns of a continuous element made of a composite thermoplastic incorporating these reinforcing means, so that this pipe enables electrostatic charges to be eliminated through its inner layer and electrical charges due to lightning to be deflected through its outer layer while having a high modulus of inertia and reduced mass.
