This was the single-engine F.l70 Jabiru which was a high-wing strut-braced monoplane of wooden construction with fabric covering. The thick wing was untapered and had sawn-off tips, the deep fuselage had a cabin for up to eight passengers, and the open cockpit was on the port side over the wing leading edge. The power plant was a 500 hp Farman 12We twelve-cylinder liquid-cooled V-engine, its exhaust manifolds were carried over the wing, and there were retractable radiators in the sides of the fuselage aft of the passenger cabin. There was a small stub wing from which a set of parallel struts ran to the mainplane at about mid-span and another set ran to the wing root.

In the pictured prototype, the stub wing had anhedral, and by attaching the landing gear wheels directly to the stub the fuselage was almost in contact with the ground. In production aircraft the stub wing was horizontal and the landing gear consisted of two streamlined Vs attached to the stub ends, and with bent axles running from the wheels to the bottom longerons of the fuselage. The prototype also differed from production aircraft in having an unbalanced rudder. When shown in the 1926 Paris Aero Show the F.170 had an enclosed cockpit. Thirteen F.170s (including the prototype) were built, the first entering service on May 26, 1926.

A very slightly larger version, of mixed construction, was the F.170bis, which could carry up to nine passengers and had increased range. Of this version, four were built for the Farman Line, an additional two were converted from F.170s. One F.170bis was temporarily fitted with a Gnome & Rhône Jupiter 9Ab air-cooled radial engine.

There was also an F.171, which was rather heavier, had further increased range and was also operated by Farman Line.

At its formation in 1933, Air France took over five of the F.170 series aircraft, but does not appear to have used them, and none remained on the register in 1934."
