Lioré et Olivier LeO 21

__NOTOC__

The Lioré et Olivier LeO 21 was a 1920s French biplane airliner and later military transport based on the earlier LeO 20 night bomber.

Development

First flown in August 1929 the LeO 21 was a twin-engined biplane airliner with a fixed tailskid landing gear. It retained the basic structure of the LéO 20 night bomber but with a new wider fuselage. It had room for six passengers in a nose cabin and a further 12 passengers in the main cabin with an open cockpit for the pilot.

The second LéO 21 was fitted with two 450hp (336kW) Renault 12Ja engines and re-designated as a LeO 212, it was converted by the Wagons-Lits company as a "dining aircraft". The first LéO 21 became an avion-bar in 1929 and was re-designated LeO 211, it was later modified in 1931 with Renaul engines as the LeO 213. One aircraft was produced as the LeO 21S fitted as a 10-stretcher ambulance. The first production LeO 213 was built in 1928 and a total of eleven were built and operated on routes from Paris to London, Lyons, Marseilles and Geneva. The LeO 213 had an increased wingspan, improved sound proofing and three baggage holds. When modified for night services they were re-designated as LeO 213N. In 1934 all the surviving LeO 213s were bought by the French Air Force and were converted to transports for 14-troops on bench seats and re-designated LeO 214.
