The FBA Type B (or 100hp) and the similar Type C (or 130hp) were French World War I single-engine pusher biplane reconnaissance flying boats used for anti-submarine patrols.

Development

The Type B and C had two bay wings and otherwise only differed from each other in the type of rotary engine installed, with the type B using a 100 hp (75 kW) Gnome Monosoupape and the type C using either a 110 hp (82 kW) Clerget 9Z or 130 hp (97 kW) Clerget 9B. Both versions had a pusher engine mounted with the propeller behind the wings, and the engine supported by numerous steel struts. They were developed from the much smaller FBA Type A, which had a single bay wing and a prominent fin ahead of the rudder, which the type B and C lacked.

These were unequal-span biplane flying boats with a single step hull built around ash longerons skinned in laminated wood and divided by bulkheads into eight compartments. The empennage was carried on an upswept curved extension of the hull and braced with steel tubing. The pilot and observer sat side by side in the open cockpit.^[2]
