Stinson Aircraft Company

The Stinson 108 was a popular general aviation aircraft produced by the American airplane company Consolidated Vultee, from immediately after World War II to 1950, when the company was bought by Piper Aircraft. Production continued for a few years under Piper.


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, and 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.

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.


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

  • The 108 does not have a right-side cargo door on the fuselage;
  • The 108-1 does have a right-side cargo door on the fuselage;
  • The 108-2 was essentially the same as 108-1, with exception of 165
    HP replacing 150 HP engine & inflight adjustable rudder trim
  • 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.
  • The “Station Wagon” version of the -3 incorporated wood paneling
    and a reinforced floor, allowing 600 lbs. of baggage in the passenger
