Registration Number 7981 (Registered as “NX,” "NR" and “NC”)

Engine Test Bed And Weather Observer

This aircraft is an Alexander Eaglerock A-1, S/N 696. It was manufactured during October, 1928 by the Alexander Aircraft Company, Colorado Springs, CO. It came from the factory with a 130 HP Hallett engine S/N 12706. It weighed 2,491 pounds. It landed at Tucson three times.

It was sold on October 3, 1928 to the Aero Corporation of California, Los Angeles, CA (President Jack Frye; Treasurer Paul E. Richter, Jr.). It was purchased, “To test performance of Hallett motor in Eaglerock plane.” Aero sold it on October 11, 1928 to E. Burrell Smith of Los Angeles. Pilot Burrell Smith landed twice at Tucson with the airplane in “NX” markings.

The first landing was on Thursday, November 15, 1928 at 1:00PM. It was southeast bound from Phoenix, AZ to Douglas, AZ. The second visit was on Saturday, November 17, 1928, reversing its itinerary back to Los Angeles via Tucson and Phoenix. For both landings, the airplane was flown solo by pilot Smith.

The Hallett must not have worked out, because on March 22, 1929 it was removed and replaced with a Wright J-4B (S/N 6974) with factory motor mount and cowling. The airplane had accumulated 56 flight hours. The “NX” registration was changed to “NC." Below, a sharp image of the airplane, , in NC livery, courtesy of Tim Kalina.

The airplane sold on June 10, 1929 to Edward T. Kersten of Los Angeles. He changed his address and moved it to Wisconsin. We find the airplane at Tucson for the third and final time on Tuesday, July 16, 1929 piloted by Mr. Kersten carrying passenger K.C. Apperson. They were inbound from Phoenix, AZ on their way to Green Bay, WI.

NC7981 changed hands four times, remaining in Wisconsin, Minnesota and Michigan. On August 13, 1937 it was bought by Northern Michigan Air Service of Sault Ste. Marie, MI. Unidentified Weather Bureau instruments were installed, the registration was changed to “NR”, and it was used under contract, “solely for Weather Bureau observation flights.”

About a year later, on August 23, 1938 it transferred, with about 650 total flight hours, to Northern Air Service, Grand Rapids, MI. The Weather Bureau instruments were removed. On July 14, 1939, at 7:30PM, it was, “destroyed by fire in private hangar No. 1” at the Grand Rapids airport.
