The Caudron Type L was a two-seat French pusher configuration amphibious biplane, flown around 1913 and intended for naval use.

The Type L had three sets of parallel and vertical interplane struts on each side, the innermost close to the central nacelle and bracing the centre section.

[1] The inner struts, to which the engine was attached, were ash and the remainder hollowed-out spruce; all joined the rather close pairs of spars in the upper and lower wings.

The nacelle ended behind the forward wing spar, ahead of the 100 hp (75 kW) Gnome Delta nine cylinder rotary engine mounted on the rear interplane struts and driving a two blade propeller via 2:1 reduction gearing and a long shaft to clear the trailing edge.

At the extreme tail, the final vertical frame member served as the axis for the rudder, with a small, roughly triangular fin ahead of it.
