The Lioré et Olivier LeO H-22 was a French amphibious plane, primarily intended for aerial mail transport.
The LeO H-22 was a flying boat with a three part cantilever high wing, primarily of both wood and metal construction.
The Gnome-Rhône 5Bc 5-cylinder radial engine, driving apusherpropeller, was mounted in a streamlined nacelle, supported on struts, over the wing centre-section.
The LeO H-221 three-seat trainer flying boat, derived from the H-22, differed in cockpit arrangement and was powered by a 230 hp (170 kW) Salmson 9Ab 9-cylinder radial engine, also driving a pusher propeller.
