No 3: In 1909 in St Die Emile Bonnet founded with Dutheil, Chalmers, and others the Societe Aeronautique de l'Est, and the Avia Company, which built machines for SEA. Avia's chief engineer was Charles Roux, who is likely to have worked on the Bonnet-Labranche No 2, since No 3 featured many similar details. With the No 3 appeared the designation ABL (for Albert Bonnet-Labranche): it was a small biplane called vedette militaire in the Avia catalogue (see Avia No 1); and another similar machine was built for the Russian Teretchenko. It had a biplane tail unit with central rudder, rectangular wings with interplane ailerons, as on No 2; a flat front elevator was rigged forward, also like No 2. The undercarriage was typically Voisin, as on both earlier Bonnet-Labranche designs; a 24 hp Dutheil et Chalmers drove a pusher propeller.

No 5: This unsuccessful biplane was tested in 1910; it may have been also the Avia No 3, first flown at Issy in August 1910, in the presence of Charles Roux.
