The Spartan 12W Executive was a tricycle gear post-war development of the Spartan 7W Executive, produced by the Spartan Aircraft Company.[2] The 12W was intended to have higher performance and be more economical than the 7W.[1]
Design and development
After World War II, Spartan aircraft Company president J. Paul Getty was unsure of the market potential of a new executive aircraft.[3] After building just one model 12W Executive (NX21962), the manufacturer lost interest in luxury aircraft and focused on constructing travel trailers instead.[4] The sole example produced was owned by Spartan Aircraft and employed at their flight training school in Tulsa, Oklahoma.[1]
The Spartan 12W Executive features magnesium alloy wings and tail surfaces and range extending wing tip-tanks. The magnesium alloy skin quickly corroded and was replaced with aluminum alloy. The tip-tanks were also removed.[1]
Aircraft on display
Spartan Aircraft flight training school eventually sold the Spartan 12W. Over the years, the aircraft passed through a number of private owners' hands. The 12W was restored in 1967 and in 2012 was retired. The 12W is now on static display at the Tulsa Air and Space Museum & Planetarium.[5]
