FORD 4-AT NC5092

FORD 4-AT NC5092


This airplane is a Ford 4-AT tri-motor (S/N 4-AT-19; ATC unidentified) manufactured May 1, 1928 by the Stout Metal Airplane Company (Ford Motor Company), Dearborn, MI.  The 4-AT was Ford’s second tri-motor design, “featuring” an open cockpit for the pilot.  It came from the factory with three Wright J-5AB engines (S/Ns L 8360, R 8362, C 8990) of 220 HP each.  It was a twelve-place airplane, weighing 10,000 pounds.  It carried the marking, “Standard of California No. 1”.  Refer to Boeing NC381 to learn about “Standard of California No. 2”

It sold on May 7, 1928 to the Standard Oil Company of California, San Francisco, CA for $50,300.  During March 1929 it was rebuilt at the Ford factory to 4-AT-E standards with Wright J-6 engines (S/Ns 10224, 10227, 10222), center section rebuilt (which probably included an enclosed cockpit you can see in this photo, and ATC # 132 assigned.

This image, from this link, page 72, shows NC5092 as she participated in the Ford Reliability Tour of 1928.  Standard Oil of California provided free fuel to Tour participants, as did Standard of Indiana, Continental Oil Company, and The Texas Company.

Below, courtesy of the San Diego Aerospace Museum Flickr Stream (SDAM), is an undated photograph of NC5092. Interestingly, the Buhl in the foreground, NC6873, is also a Register plane, visiting Parks Airport in East St. Louis, IL in February, 1930. The people are unidentified. If you can help identify them, please let me KNOW.

Tucson saw NC5092 twice, on December 14, 1928 and March 1, 1929.  Based in San Francisco, CA, the pilot both times was F.V. Tompkins.  On December 14th he carried six unidentified passengers on a round-robin to and from Phoenix, AZ.  On March 1st he carried a single passenger, a Captain S.S. Chadderton.  Capt. Chadderton was Manager, Aviation Division of Standard Oil of California.  They were eastbound from San Francisco, CA to Detroit, MI.  This flight is probably the one that took the airplane to the factory for its upgrade to 4-AT-E standards (see above).

NC5092 flew with Standard Oil until 1931.  On August 13, 1931, the airplane sold to Jack W. Thornburg, Grand Canyon, AZ.  It transferred immediately on the 14th to the Ruckstell Corporation, Ltd., Glendale, CA, then to Grand Canyon Airlines, Inc., Grand Canyon, AZ on October 9, 1931.  Glover Ruckstell, a pilot of the Register, provided cash flow for the Depression-saddled Grand Canyon Airlines.

The airplane flew with Grand Canyon until 1934 when it sold to Vernon Bookwalter, Seattle, WA.  Six months later, on November 24, 1934, it was sold to White Pass Airways, Inc., Skagway, AK.  It stayed in Alaska until 1940. On January 30, 1940, the airplane struck a hangar upon landing and was “washed out”.  The pilot was Vernon Bookwalter.  No further information.
