C-71 Executive

The Spartan 7W Executive is a cabin monoplane aircraft that was produced by the Spartan Aircraft Company during the late 1930s and early 1940s. The 7W features an all-metal fuselage, as well as a retractable undercarriage. The 7W Executive was popular with affluent buyers worldwide."American airplanes: Spartan."

Design and development

Designed expressly for the executive market, the Spartan Executive was configured for both performance and comfort. Built during the Great Depression, the 7W was the brainchild of company-founder William G. Skelly of Skelly Oil who desired a fast, comfortable aircraft to support his tastes and those of his rich oil-executive colleagues. Through a series of acquisitions, J. Paul Getty took over ownership of the Spartan Aircraft Company in 1935, and directed its fortunes from that point to 1968.Peek and Goodhead 1994, p. 150.

The interior of the 7W is spacious and features of slide-back seat room for front-seat passengers, armrests, ash trays, dome lighting, deep cushions, cabin heaters, ventilators, soundproofing, large windows, and interior access to the capacity luggage compartment. The interior can be configured for four or five passengers.Taylor 1989, p. 983.

In 1938, Spartan published a concept brochure for a possible future military aircraft, the model 7W-F. Using existing photographs of Spartan Executive serial number 10 that was painted in a unique paint scheme and was registered as NC17610, artists modified those photographs to show the possibilities of the concept airplane. The photo enhancements incorporated two forward-firing .30 calibre machine guns mounted on the port side near the firewall and firing through the propeller arc through a synchronized mechanism. A further enhancement showed a gunner's station at a dorsal hatch on the roof with a windscreen and machine gun fitted. Bomb racks under the wings were also shown in the enhanced photos. The program never went beyond the concept brochure.Savage, Jim. ''Vintage Spartan Aircraft'', 2022, pp. 5-32

Following up on the 7W-F concept, Spartan then built a two-seat military variant of the 7W Executive, named the Spartan 8W Zeus. The aircraft featured a greenhouse canopy covering a tandem cockpit and was powered by a more powerful Pratt & Whitney Wasp engine. The 8W was designed as an advanced trainer for military use. Only one example was built and Spartan was unsuccessful in marketing the airplane. It eventually became a training aid for the Spartan School of Aeronautics in Tulsa, Oklahoma.Savage, Jim. ''Vintage Spartan Aircraft'', 2022, pp. 91-97.

Including the 7X prototype and the three-seat 7W-P photo reconnaissance model that evolved from the second prototype and was exported to China, 36 aircraft are generally referred to as Spartan Executives. Of the 36, only 34 are actual model 7Ws. The last 7W, serial number 34, was completed in September 1940.

In 1942, a total of 16 7W Executives were impressed into military service with the United States Army Air Forces. The 7Ws served as executive transports for military staff as the UC-71.

A post-World War II effort to rekindle interest in the Executive series, under the re-branded Spartan 12-W designation, failed to gain interest. Only one Model 12 was completed, and today is part of the Tulsa Air and Space Museum & Planetarium collection.

As of February 2022, a total of 20 model 7Ws still exist. Fifteen are based in the US, two are in England, one in Germany, one in France and one in Russia.

Operational history

In April 2023 there were 19 Spartan 7Ws and one Spartan 12 remaining on the US Federal Aviation Administration aircraft register.

Notable owners of 7Ws include: American entrepreneur, aerospace engineer and founder of Garrett AiResearch, John Clifford Garrett; American aviator and air racer, Arlene Davis; American aviator, air racing pilot, and movie stunt pilot, Paul Mantz; wealthy industrialist J. Paul Getty, ; and King Ghazi of Iraq. King Ghazi's Spartan Executive was designated "Eagle of Iraq" and was outfitted with his coat of arms, an extra-luxurious interior and customized features. Although not an owner, aircraft designer and aviator Howard Hughes is often associated with the Spartan Executive due to his involvement with America's War Bond Campaign. During January 1943, Hughes was provided with one of the USAAF Spartans for his use in traveling from city to city promoting those bonds.

Variants

;Spartan 7X Executive
: (Also known as Standard Seven) The first prototype, was fitted with a Jacobs L-5 radial engine for the initial flight. All subsequent flights were made with a Jacobs L-5 radial engine. The 7X initially had a very small tail. Only one was built and after the type certificate was received for the production model 7W, it became a training aid for the Spartan School of Aeronautics in Tulsa, Oklahoma.

;Spartan 7W-P Executive
:Second prototype evolved into a three-seat photo reconnaissance model, similar in appearance to the thirty-four 7W production models. The 7W-P was produced in accordance with Type Certificate 646. The sole example, 7WP-1, was exported to China in 1937.

*Chinese Nationalist Air Force
The only 7WP photo reconnaissance Spartan built was exported to China and it display identification number 1309. It was damaged beyond repair and captured by the Japanese who displayed it along with other captured Chinese aircraft.
;
*Spanish Republican Air Force/Aviación Nacional
At least one example was received by the LAPE (Líneas Aéreas Postales Españolas) to be used as an airliner marked as EC-AGM until requisitioned by the Spanish Republican Air Force and marked as 30+74. It was later captured by the Nationalists. Several others were purchased by the Republicans.
;
*Royal Air Force
Four Spartan Executives were part of the Royal Air Force during World War II. One example (AX666) was built for King Ghazi of Iraq. The King died just prior to completion of the airplane, so the RAF acquired it. The airplane was used by No. 1 Photographic Reconnaissance Unit RAF but was destroyed in a landing accident in Montrose, Scotland in January, 1941. Three other examples were purchased by the United Kingdom Government in December 1940 and were used to provide refresher training to American pilots who would ultimately go on to serve in the RAF. When used for that purpose at Polaris Flight Academy in Glendale, CA, they continued to carry their U.S. civilian registration numbers of NC17604, NC17617 and NC17630. On January 1, 1943, these three Spartans officially became Royal Air Force aircraft and were given RAF serial numbers KD100, KD101 and KD102. The Spartans were assigned to the RAF Ferry Command in Dorval, Canada. Although based in Canada, they were never part of the Royal Canadian Air Force. They were returned to civilian ownership in the US after the War and all were reregistered with their original civilian registration numbers.
