Bessard-Millevoye Moineau (Sparrow) was a single seat, low-powered French biplane intended to increase participation in popular aviation.

It was low-powered, making it relatively cheap to build and run, and folding wings made it compact to store.

The prototype was fitted with a 26 kW (35 hp) Mengin B flat twin, which resulted in a rather blunt nose with engine cylinders exposed for cooling.

At the rear a triangular tailplane carried unbalanced elevators with a cut-out for the movement of a large balanced rudder which together with a small fin formed a blunted quadrant.

The Moineau had a fixed, wide track, tailskid undercarriage, with large, low pressure balloon tyres on half-axles formed on each side by three struts, a forward pair from the lower and mid-fuselage and a drag strut to the lower fuselage further aft.
