The upper wings of the Nieuport sesquiplanes used a typical structure for the period, with widely spaced spars connected with full chord ribs and compression ribs, cross-braced internally with wire and by riblets on the leading edge. The lower wing's single spar was directly below the rear spar of the upper wing and was braced with a characteristic Vee strut. The ribs, composed of ash flanges and limewood webs, featured cut-outs to lighten them. Ailerons were fitted on the top wing only and had increased chord towards the wingtips for improved stall response. They were actuated by a pair of push-pull rods that connected torque tubes running to the ailerons to the control column in the cockpit. The horizontal stabilizer, elevator and rudder were built up from welded diameter steel tube and controls for these were provided via conventional cables and pulleys. The angle of incidence on the wings could be adjusted by ground crew via a single pivot joint arrangement, which was originally intended to allow the lower wing to be rotated for low speed flight on the Nieuport 10, but was never used. No adjustment was provided for the tailplane.
