Stinson 108 and Franklin
Documentation and Manuals
The Type Certificate for the Stinson model 108 series airplanes requires either a copy of the "Approved Operating Limitations" or the "Approved Airplane Flight Manual" for the specific model Stinson 108 which must be in the airplane during flight. Univair has printed versions of these documents available for sale. Each airplane has an unique Approved Operating Limitations, or an Approved Airplane Flight Manual for the specific model and specific airplane. This is NOT the "Owner's Operating Manual."

Stinson 108-1 Landplane Approved Operating Limitations dated June 4, 1947 pdf, about 1.1 meg,
Stinson 108-2 Landplane Approved Fligt Manual dated January 4, 1949 pdf, about 394K,
Stinson 108-3 Landplane Approved Fligt Manual dated December 29, 1948 pdf, about 789K,

In addition to the Approved Operating Limitations, or Approved Airplane Flight Manual, also required is a current weight and balance sheet including an equipment list for each specific airplane. Files are in PDF format, added 08/14/12, updated 12/01/20.

Each airplane has two documents which are unique to each individual airplane, the equipment list and the weight and balance. Stinson delievered each airplane with an Equipment List included in the airplane flight manual, with this 108-3 Airplane Flight Manual the equipment list is on page 4 of 4. NOTE the airplane flight manual is not the pilot operating handbook. The flight manual is a separate document unique to each airplane. Stinson listed all optional equipment and "X'ed" out equipment items NOT installed at the factory. PDF format, about 416K. With the equipment list created then the airplane was weighed. Here is a sample of a Stinson Weight and Balance measurement from the factory. This weight and balance is for the same airplane as flight manual equipment list. When this weight and balance was performed there was oil in the engine of 17 pounds which is not part of the empty weight, and there was no fuel in the tanks of which the unusable fuel of 4 gallons, 24 pounds, is part of the empty weight. So the weight as weighed is 1,308 pounds, minus 17 pounds for oil, and plus 24 pounds for unusable fuel, giving an actual airplane empty weight of 1,315 pounds. In addition to the weight, the report also provides the moment so weight and balance can be calculated with people, fuel, oil, and optional equipment added. IMPORTANT Stinson model 108 series were last manufactured more than 70 years ago. It is very important that your airplane carry documents which represent changes made since manufacture, such as newer radios, etc. PDF format, about 167K. Added 09/01/17, updated 12/01/20.

From the Stinson Dealer Sales guide gives the 1948 Voyager and Flying Station Wagon 108-3 performance data comparing the standard wood propeller which is the Sensenich 76JA-53 or 76JR-53 that weights 14 pounds, with the "special equipment propeller" which is the metal McCauley 1A170 DM7453 that weights 33 poungs. So improvements in take off distance, rate of climb and cruise speed, with the metal McCauley propeller causes a reduction in useful load of about 19 pounds.

From the Stinson Dealer Sales guide gives the 1948 Voyager and Flying Station Wagon 108-3 factory weights for different configurations. This chart compares the standard airplane, the Voyager, with the Stinson Flying Station Wagon, in different landplane and seaplane configurations. From the factory the useful load ranged from 1009 to 1106 pounds with standard equipment. There are 26 pounds of additional weight in the Flying Station Wagon because of the reinforced floor under the rear seats, and the additional weight of the wood panels in the back seat area. All of the weights shown are shown with the standard wood propeller in both landplane and seaplane configurations. The standard wood propeller is the Sensenich 76JA-53 or 76JR-53 which weights 14 pounds. If the "optional special equipment propller," the metal McCauley 1A170 DM7453, is installed it weights 33 pounds which reduces useful load by 19 pounds in each case.

Stinson changed to installing only the Ski axel on the 1948 Voyager and Flying Station Wagon 108-3 at serial number 108-4125. Stinson serial numbers 108-1 to 108-4124 came standard with the land plane axel, Stinson part number 108-5111004. If the owner wanted to use skis they had to change the axel to Stinson part number 108-5611001. From serial number 108-4125 on only the ski axel was installed and could be used either as a landplane, or a ski plane. Adobe Acrobat PDF format, about 136K. added 07/10/16.

My thanks to David Martin for sending me the image of the CA-2 radio still installed in 108-2 N9429K. All Stinson model 108s were delivered from the factory with a direction finding capability. Keep in mind this was before the days of VORs, LORAN or GPS. Shown here is the fixed loop antenna installed inside the fuselage (this antenna worked because all factory delivered Stinson 108s were fabric covered). Added 1/27/01, Last updated 11/28/04.

All Stinson 108's came from the factory with a two way radio, which had to be licensed as an aircraft radio station with the FCC (Federal Communications Commission), not the CAA (Civil Aeronautics Authority, now the Federal Aviation Administration). To obtain the aircraft radio station license circa 1948 the aircraft owner was required to provide the radio specifications to the FCC. Stinson provided radio specifications to apply for a aircraft radio station license. The frequency shown, 3105 Kc was later changed by the FCC to 3023.5 Kc on March 15, 1953.

The Stinson Twins!
When Piper Aircraft purchased the Stinson Division of Consolidated Aircraft in late 1948, included with the Stinson sale were the drawings for a new twin engine airplane designed by Stinson. Piper went on to build this airplane, initially naming it the "Twin Stinson." This photograph shows the Prototype Twin Stinson on the ground shortly after its first flight in March 1952. Registered N1953A, with Piper serial number 23-01. Here is a second photograph of the Prototype Twin Stinson in Flight. This airplane was a true milestone aircraft for Piper. It was the the aircraft which took Piper from the manufacture of tube and fabric "puddle jumpers," into the world of all metal business aircraft. This airplane was later marketed by Piper as the "Apache," first of Piper's American Indian named products. Later it evolved into the definitive Piper Aztec. Added 8/1/00, Last updated 01/18/03.

A really Unique "Twin Stinson". This article details a rather unique airplane built up from two others, a Stinson 108 and a Langley twin.

Here is an inflight view of the Langley type airplane whose wing, center section and engines were used along with the Stinson 108 fuselage to create the "Pierce-Arrow" model U-2. Click to view the 1943 Langley Twin 2-4-90. This airplane is the prototype, registration NX29099. Of all wood construction using the "Vidal" process of plastic bonded plywood. Finish on this first example is clear varnish to emphasize its wood consturction. Powered by two Franklin 4AC-199-E3 engines of 90HP each driving fixed pitch propellers. Could seat 4 people, however the useful load was better suited for 2 or 3 people. First example built in 1943, then after WWII ended there were 2 or 3 additional examples manufactured. Langley's built after WWII had the wood covered with fabric for protection from the elements. B&W, about 311K, Added 01/01/16.

Here is an in-flight view of the unique Twin Stinson Pierce-Arrow. And a second image of the Pierce-Arrow in formation with a Pitts Special. Recently heard more information about this this airplane, it is now being stripped and inspected. Updated information as of 03/02/01 from owner Jimi Genzling - As it stands right now the Fuselage has completed it's final inspection prior to covering, which will probably start in a couple of week's. It has passed with "Flying" colors. The wing center section is the next project so as to get her back on her own feet. Am in the proccess of building a new wiring harness and completing the interior electrical and rigging prior to covering. Jimi Genzling indicates he would be interested in selling or trading this unique "Twin Stinson" for a high wing project. If you're interested contact the "Desert Eagle" at jimi@hdc-nm.com for more information. Jimi Genzling now has a web page about the unusual "twin Stinson."
