The Lioré et Olivier LéO H-13 was a French biplane two-engine flying boat of the 1920s, built in passenger and military variants.

Development

The LeO H-13 was constructed by Lioré et Olivier in Levallois-Perret factory, for an order of the French Aeronavale airlines. The prototype was flown in July 1922. From 1923 23 passenger aircraft were built LeO H-13A.

Next, military variants were developed: reconnaissance-bomber LeO H-13B-3 and trainer LeO H-13E. They differed in fuselage configuration, because the H-13B-3 had an open cockpit for a pilot only behind a lower wing, while the H-13E had an open cockpit for a trainee and instructor seating side-by-side, in front of wings. Both had open machine gun positions in the nose and behind the wings. The H-13E could be also used as a reconnaissance aircraft. From late 1923 20 H-13B-3 were built (nos. 1-20) and 10 H-13E (nos. 21-30).

Service

Passenger H-13A were used over the Mediterranean Sea.

In the French Navy, H-13 were quickly withdrawn for training purpose, because of weak structure and low manufacturing quality.

In 1924-1925 two H-13B3 and two H-13E were sold to Poland and used in Naval Aviation Unit (MDLot) in Puck from mid-1925. One of H-13E was used for a short time in a River Flotilla in Pińsk. The first H-13B-3 no. 1-1 was withdrawn in 1929, next two (nos. 1-2 and 1-3) in 1931, while the last H-13E, no. 1-4, crashed on 29 July 1931 over the land near Puck.
