This tri-motor transport airplane is a Stinson Model U (S/N 9000; ATC #GR 2-413) manufactured on March 30, 1932 by the Stinson Aircraft Corporation, Wayne, MI.   It was the first of the Model U series of 23 examples to be manufactured. NC432M left the factory with three Lycoming R-680 BA engines (S/Ns L 695; R 696; C 697) of 240 HP each.  It was an eleven-place airplane (two pilots), weighing 9,000/ 9,300 pounds gross.  Its “stub” wings (sesquiplane) sometimes resulted in this aircraft being referred to as a biplane. You may see an image of this airplane on this page. Another image is on the first page of this article published in the Journal of the American Aviation Historical Society, Spring, 2013. Entitled, "The Stinson Model U Trimotor of 1932," (PDF 814Kb) the article summarizes the manufacture, use and technical aspects of the model.

NC432M was the prototype of the series, and was registered “NX” initially to develop servo controls and automatic ailerons.  It was flown by the company until it was sold. An image of this airplane is available here.

The airplane landed on August 22, 1932 piloted by Robert W. Cantwell.  He listed as passengers “Four Modocs” (note *, left sidebar).  Based in Detroit, MI, they were eastbound from Los Angeles, CA to Cleveland, OH.  In the Remarks column of the Register, Cantwell noted, "Riding herd on Cord Cup Race".   The National Air Races for 1932 began in Los Angeles and, except for the trans-continental events, which went to NY) terminated at Cleveland. A couple of our pilots also landed about the same time as Cantwell. See the pages for Jean LaRene and Bob Buck.

Although “NC” is clearly written by Cantwell in the Register, the NASM record states that the NX certification was in effect until December 15, 1933.  Regardless, the “NX” certification period was not allowed to expire.  The NASM record says the registration was approved for “NC” on August 27, 1933 as an eleven-place transport airplane.

The airplane sold on May 2, 1934 to Licon Airways, Inc., Islip, NY.  There is nothing in the record that suggests what Licon Airways did with the airplane, or how it was maintained.

Less than a year later, on March 23, 1935, NC432M was sold to R.L. Baker, St. Petersburg, FL.  As of May 7, 1936, Mr. Baker had the 240 HP Lycoming engines replaced with three engines of 215 HP.

On September 4, 1937, the airplane was sold to National Airlines, Inc., St. Petersburg, FL.  The wings were rebuilt and re-covered, and the fuselage top and bottom were re-covered as of September 9, 1939.  National sold it to Dexter Eugene Richmond and James Fred Wood on February 17, 1941.  There was no address listed for Richmond and Wood, but they probably lived in Florida.

In answer to an FAA enquiry, Richmond and Wood stated in their letter of February 4, 1948 that the, “…airplane had been sold in March, 1942 to a government school at the airport in Dunnellon, Fla. as an instructional airframe.”  No further information.

*Here is an interesting example of how slang changes through the decades.  A “modoc”, during the Golden Age, was defined as follows:

Modoc (mō´dŏk) n. [U.S. slang, now rare] (origin unknown, also modock) a person or pilot who talks boastfully about flying, but rarely flies.

Today, we might refer to modocs as "hangar fliers."

And Modoc is the official name of a Native American tribe on the U.S. west coast. No offense is intended, nor should any be inferred from your Webmaster's reportage on the use of the word during the Golden Age. See the CODE OF ETHICS.
