The FN.333-S is the production development of the previously-described FN.333. It is powered by a 225 hp Continental engine, has accommodation for four persons and is fitted with a novel form of wing-folding. The wing of FN-333-S is in five sections, consisting of centre-section and four outer sections, two each side, the inboard sections being hinged to fold upward and the outboard sections downward. The wing folding and unfolding, which is controlled form the cockpit by a system of hydraulic jacks, is automatically synchronised to ensure that, when the aircraft is afloat, the wing-tip floats are in constant contact with the water so as to maintain lateral stability. There is an independent control for normal wing-tip float retraction and lowering.
