In the 1930s the veteran aircraft designer Louis Béchereau set up Avions Kellner-Béchereau, a collaboration with the well-known automobile coach builders Kellner.

Both of these were designed to meet the French Air Ministry's requirement for a pre-military trainer aircraft to be used by the clubs set up in the "Aviation Populaire" programme.

It was a mid-wing cantilever monoplane with straight, thick section, constant chord wings of quite high aspect ratio (9.45).

A straight edged tailplane was mounted on the upper fuselage longerons and carried elevators with a small cut-out for rudder movement.
