The 14's type number was reused for an unrelated parasol wing prototype that was basis of the more successful Latécoère 17.
[1][2] The Latécoère 14 was powered by a 220 kW (300 hp) Renault 12Fe water-cooled V12 engine in the nose with its rectangular radiator in front of a flat-sided cowling.
[1] Behind the different engines of the two models, the basic fuselage was the same duralumin tube structure for each, the surface defined with wooden stringers.
[1][2] The metal-framed, canvas covered empenage was conventional, with a clipped-triangular tailplane bearing straight-edged, balanced elevators with angled tips.
The two models had somewhat different fins, the 14's short and trapezoidal, the 16's taller and almost triangular, mounting a tall, broad, unbalanced rudder which reached down to the keel and worked in an elevator cut-out.
The mainwheeels were on a single faired axle provided with shock absorbers and supported at each end with W-struts from the lower fuselage.
