The Jodel D.9 Bébé is a French single-seat ultralight monoplane designed by Jean Délémontez for amateur construction.

[1][2] In March 1946, Edouard Joly and Jean Délémontez formed the Société des Avions Jodel to supply kits, materials and plans to allow homebuilders to construct an ultralight monoplane designed by Délémontez and named the Jodel D.9 Bébé.

The D9 was a wooden low-wing cantilever monoplane with a single-seat open cockpit and a fixed tailskid landing gear.

Ben Keillor translated the French kit plans to English in 1959, and constructed and demonstrated a D9 in Canada and America.

Jean Delmontez scaled up the D.9 to produce plans for a three-seater powered by a 75 to 85 hp (56 to 63 kW) engine, but was persuaded by SALS (the Light Sport Aircraft Service of the French Government) to build the two-seat D.11 to provide training aircraft for French aero clubs using the wing of the D.10.
