The Lioré et Olivier LeO H-180 was a 1920s French two-seat flying-boat built by Lioré et Olivier.[1]

Development

The H-180 first flew in 1928 and was a cantilever high-wing monoplane flying-boat.[1] Powered by a 120 hp (89 kW) Salmson 9Ac engine strut-mounted above the fuselage.[1] It had two side-by-side seats in an open cockpit but the following year it was fitted with an enclosed cockpit and re-designated the LeO H-181.[1] The company intended to build a production batch of ten aircraft but only five H-181s were built.[1] One aircraft was destroyed and the others finding no buyers were used as test aircraft by the company.[1]

Variants
