Admin/Biographical History These plans were created so that Delta aircraft mechanics could build - completely in house - three Huff Daland Duster crop-dusting airplanes, Ship 70 (NR17606), Ship 71 (NR17607) and Ship 72 (NR17608), for Delta's Dusting Division, based in Monroe, Louisiana, in 1937.

Working from Huff Daland Airplanes' original plans, this set was revised, drawn and traced by H.E. "Herb" Dickard, Jr. an engineering student, in June-July 1936. He worked with Delta in Monroe for several years, daily during the summers and on Saturdays while attending school.

In a letter to his son, H.E. Dickard, III, dated October 1991 (Delta Flight Museum Accession 1998.3), Herb Dickard recalled that Delta had acquired the patents to the Huff Daland Duster and intended to build more of the aircraft for its growing crop-dusting operations. Delta's original set of plans had been destroyed by rodents and were unusable. He was asked by Delta General Manager C.E. Woolman to draw to scale the Huff Daland Duster and create a new set of plans.

Herb Dickard recalled that ten people built the three new crop dusters "from scratch" in 1936-1937, while maintaining the other airplanes in Delta's fleet. The new crop dusters did not have a known airplane factory name, but Delta General Manager C. E. Woolman worked things out with the Civil Aeronautics Administration (CAA, now the FAA) by declaring the aircraft as experimental.

Delta's earlier Huff Daland Dusters were built by Huff Daland Airplanes, Inc., later renamed the Keystone Aircraft Company. The Huff Daland Duster was the first aircraft designed for crop dusting.
