The Stinson 108 was a popular general aviation aircraft produced by the Stinson division of the American airplane company Consolidated Vultee, from immediately after World War II to 1950. It was developed from the prewar Model 10A Voyager. Stinson was bought by Piper Aircraft. All Stinson model 108, 108-1, 108-2, 108-3 and 108-4 aircraft were built by Stinson at Wayne, Michigan. When Stinson sold the type certificate to Piper in 1948, approximately 325 airplanes of the 5,260 model 108's built by Stinson were complete but unsold. These 325 model 108's went to Piper as part of the sale. Piper then sold that inventory as the Piper-Stinson over the next few years.

Design and production

Design features
The fuselage was of fabric-covered steel tube. Aftermarket modifiers have obtained supplemental type certificates (STC) allowing conversion to an aluminum covering. Many different engines have been installed in the 108 by STC such as the Lycoming O-360, Franklin 220|220, Continental O-470.

One distinctive feature was the partial leading edge slot installed on the wings and aligned with the ailerons on the trailing edge, ensuring that the portion of the wing containing the aileron remains unstalled at higher angles of attack, thus contributing to docile stall behaviour.

Production
Total new production of the Stinson Model 108, by Stinson, was 5,260, total does not include the 2 converted prototypes. Stinson delivered approximately 4,935 aircraft and Piper delivered approximately 325 aircraft. Piper later sold the type certificate to Univair. Univair built and certified the model 108-5, 1 built. Total new model production by Stinson and Univair is 5,261 aircraft.

Model 108 gatherings

In the past, gatherings or fly-ins for Stinson owners have been held in Minden, Nebraska. Currently the International Stinson Club holds annual fly-ins in Columbia, California. Many Stinson 108 owners also gather together during the week-long at the EAA Fly held in at Oshkosh, Wisconsin each July.

Variants

The 108 variants closely resemble each other but can be visually distinguished by their design changes:

Two Prototype model 108's were converted from Stinson model 10A airframes. FAA records show NX31519 was model 108 serial number 1, and NX31532 is model 108 serial number 2. Both registrations later changed to NC. The production model straight 108 would also use serial number 1 and 2, so there was for a short period 2 duplicate serial numbers.

  • The 108 does not have a right-side cargo door on the fuselage, 741 built;
  • The 108-1 does have a right-side cargo door on the fuselage, 1507 built;
  • The 108-2 was essentially the same as 108-1, with exception of 165 HP replacing 150 HP engine & inflight adjustable rudder trim, 1252 built;
  • The 108-3 introduced a taller vertical fin whose rudder has a straight trailing edge. Larger fuel tanks (50 gallons vs. 40) were also incorporated into the wings. The -3 has a higher gross weight than its predecessors (2400 lbs.), allowing full fuel, (4) 170 pound occupants, and 50 lbs. baggage allowance, 1759 built.
  • The 108-4 was a higher powered model 108, sn 108-4693, NX149C, not certified, flown experimentally by Stinson, later by Piper, 1 built ;.
  • The "Flying Station Wagon" version was an option available with the -1, -2 and -3 models, had a utility interior incorporated wood paneling and a reinforced floor, allowing 600 lbs. of baggage in the passenger compartment. The aircraft could be fitted with wheel, float or ski landing gear. The single 108-4 was a Flying Station Wagon.
  • The 108-5 was built by Univair, similar to the 108-3 with a 180HP Franklin engine. Univair purchased the Stinson 108 type certificate from Piper, 1 built about 1975. This airplane brings total model 108 production to 5,261, of which 5,260 were built by Stinson, 1 by Univair.
    • Voyager 125
      Powered by a 93-kW (125-hp) Lycoming piston engine.
    • Voyager 150
      Powered by a 112-kW (150-hp) Franklin 6A4-150 piston engine.
    • Voyager 165
      Powered by a 123-kW (165-hp) Franklin 6A4-165-B3 piston engine.

Operators

  • United States
    No United States military use of the Stinson model 108 is known. The Stinson Voyager Production Record shows two aircraft, sn 108-2381 and 108-2382 with the notation "Army Demonstrator." Unable to locate U.S. military serial numbers for these airplanes.
  • Spain
    The Spanish Air Force, Ejercito del Aire, operated 21 model 108-3 aircraft procured from civil sources, as the Spanish L.2 and carried Spanish Air Force serial numbers L.2-01 to L.2-21.
  • France
    The French Air Force operated Stinson 108-3, serial number 108-4419, assigned to Escadrille de liaison aérienne 52. It was flown in Indochina (Vietnam) in the region near Hué in 1951. Today that airplanes flies in France registered F-BEXD.
