Your copy of the "Davis-Monthan Airfield Register" with all the pilots' signatures and helpful cross-references to pilots and their aircraft is available at the link. Or use this FORM to order a copy signed by the author. ISBN 978-0-9843074-0-1. You can see pilot Brutus' bold signature on page 202.


Some of this information comes from the biographical file for pilot Brutus, CB-845700-01, reviewed by me in the archives of the National Air & Space Museum (NASM), Washington, DC.

Lee N. Brutus, Date Unknown (Source: Heins)
Lee N. Brutus, Date Unknown

Lee Newton Brutus visited Tucson flying Waco UIC NC13578. The airplane bore S/N 3802 and it was manufactured in 1933. At the time it was owned by Waco dealer H.C. Lippiatt, Burbank, CA. Pilot Brutus is VP Waco Aircraft, Troy, OH. He carried five passengers including his wife, Edward O'Herron, Charlotte Coles, Rufus Kleinsmith and Louis F. Allen.

Based at the home office for the Waco Aircraft Company they did not date their visit in the Register, so all we know is they landed sometime between March 4 and March 20, 1934. Neither did he record their direction of flight. Nor was a purpose given in the Register for their voyage.

Brutus was an Army pilot during WWI. He was executive vice president of Waco Aircraft for 14 years, then president of Luscombe Airplane Corporation in Trenton, NJ.

Thirteen years after his landing at Tucson, on July 31, 1947, Brutus was appointed Pacific Coast sales representative for the Nylok Nut Corporation of New York. His new job was to direct the distribution of Nylok's self-locking fasteners for aviation applications and to manufacturers of appliances and machinery in which vibration makes shake-proof nuts desireable. Nyloc fasteners employ a plastic nylon self-locking element in the nut that grips the threads of the bolt. They are useful in high vibration, low-temperature (i.e. below the melting point of nylon) applications.

Below is the press release, dated July 31, that announced his new position.

Below are standard AN-type, aviation-grade nuts and bolts, not of the Nylok type. The nuts at 9:00 and 6:00 are standard fasteners. The nuts at 8:00 and 4:00 are self-locking, but, being all metal, they are for high-temperature applications where plastic, as in Nylok fasteners, might melt.

Below are Nylok fasteners. Note that the bolts are the same, but the nuts have colored nylon inserts. The inserts are deformed when the bolt is screwed into them and the plastic grips the bolt threads to keep vibration from turning the nut off the bolt. Because the plastic can melt, these nuts are used in low-temperature applications (away from the engine compartment, heater manifolds or exhaust systems).

The Register
President (as of the upload date of this page) Andy Heins of the National Waco Club sent the image at left. Andy  runs the day to day business of the Club, and we should all thank him for the effort he expended to help us understand better the Waco aircraft that landed at the Davis-Monthan Airfield way back when.
