North American Navion
Ryan L-17 Navion

Designed by, and the first thousand built by, North American, later the production was handed over to Ryan Aircraft who built about a thousand more. A large four seat all metal tourer with sliding canopy produced from 1947 to 1957.

In 1948 the original 1946 model was upgraded from 185 hp to 205 hp. The Navion B of 1951 introduced 260 hp, and the 240 and 250-hp Continentals came out in 1958 and 1959 respectively.

Original L-17A was military version of civil Navion built by North American. When Ryan took over production, 158 more were ordered by U.S.A.F. as L-17B's. L-17C is L-17A modified by Ryan. All are 4-seat liaison aircraft powered by a. The US,A.F. transferred 170 L-17s to the Civil Air Patrol during 1954.

One of the later manufacturers introduced the Rangemaster model which had conventional doors and was produced from 1962 to 1970.

Navion Aircraft Co was founded in 1965 by the American Navion Society to provide spares and support for owners of Ryan/North American Navion lightplanes. All rights to the aircraft were acquired and a developed version, the five-seat Navion Rangemaster H, was produced before the company was liquidated and taken over by the Navion Rangemaster Aircraft Company.

In 1972 Navion Rangemaster Aircraft Co purchased the assets of the bankrupt Navion Aircraft Company, including jigs, machine tools, and spare parts to support Ryan/North American Navion lightplanes. In 1973 production of the Navion Rangemaster restarted, the first aircraft flying late the following year. Consolidated Holding Incorporated acquired control of the company in 1975 and announced plans to manufacture the Rangemaster H at the rate of one per week.

The Navion Rangemaster has been in and out of production in the past, and its 1977 revival has at times seemed sur-rounded more by promises than produc-tion. Where the factory formerly sold Rangemasters direct, all selling will now be done by Two Jacks, of Olive Branch, Missis-sippi. Two Jacks has, in fact, obligated itself to accept 100 Navion Rangernasters, to be built during 1976-78.
