The American Navion Society, a club formed in 1960, organizes a annual convention and other social events for Navion owners.

Re: Ryan / North American Navion
There are no two Navions alike, in part because numerous companies produced the airplane in different parts of the country, in part due to its long service history and many approved modifications,
and because without the continuous manufacturing production and support of these airplanes for most of the last 40 to 50 years, owners and third-party organizations have successfully sought numerous improvements to the aircraft on their own via [Vous devez être inscrit et connecté pour voir ce lien] field approval and [Vous devez être inscrit et connecté pour voir ce lien].
The airplane has been repeatedly modified with numerous larger powerplants including the latest aircraft piston engine designs available.
One Navion was fitted with a Czech built [Vous devez être inscrit et connecté pour voir ce lien] allowing the airplane to climb in excess of 5,000 ft per minute.

A pair of highly-modified Navions were flown by [Vous devez être inscrit et connecté pour voir ce lien] as the Variable-Response Research Aircraft (VRA) and the Avionics Research Aircraft (ARA).
The VRA was given a pair of vertical side-force-generating surfaces mounted midway between wing roots and tips and a digital fly-by-wire (DFBW) control system, first installed in 1978, that parallels the standard Navion's mechanical control system and the fast-acting wing flaps that produce negative as well as positive lift.

With these, the VRA can simulate the motions of other aircraft types through independent, closed-loop control of all the forces and moments acting on the airplane.
Having completed over 20 years of research at [Vous devez être inscrit et connecté pour voir ce lien]'s Flight Research Laboratory, the VRA and its sister ship, the Avionics Research Aircraft (which is virtually identical to the VRA but does not have side-force panels) currently are owned and operated by the [Vous devez être inscrit et connecté pour voir ce lien] .

American military services used the L-17 from the late 1940s through the early 1960s for liaison, reconnaissance, light cargo carrying and forward air control (FAC) missions.
Six even became target drones.
Designed for civilian aviation and first flown in 1946, it was introduced commercially as the NA-154 Navion.
The U.S. Army Air Forces ordered 83 military versions under the designation L-17A.
Ryan Aeronautical Co., having bought the design and manufacturing rights from North American, built 164 improved L-17B Navions for the U.S. Air Force. Navion production ended in 1949.
Later, 35 L-17As were converted to L-17Cs with improved brakes and greater fuel capacity. During the Korean War, some USAF L-17Cs were pressed into service for a short time as FAC aircraft.
All L-17s were redesignated U-18s in 1962.
The L-17A on display was flown to the museum on April 7, 1986.
It is marked as a Ryan-built L-17B used by the Air Force ROTC program at Bradley University, Peoria, Ill., in the spring of 1959.
