The Ayres Thrush, formerly the Snow S-2, Aero Commander Ag Commander, and Rockwell Thrush Commander,
is an American agricultural aircraft produced by Ayres Corporation and more recently by Thrush Aircraft.
This single-seat monoplane of conventional taildragger configuration is one of the most successful and
long-lived agricultural application aircraft types in the world, with almost 2,000 sold since the first
pre-production prototype Model S-2 was first flown in 1956. Originally powered by a radial piston engine, most
examples produced since the 1980s have been turboprop-powered.
In 1953, Leland Snow constructed his
first crop-duster Model S-1 before graduation from Texas A&M University. The Texas A&M College
Aircraft Research Center is known from the AG-1 Agricultural plane that was designed by Fred Weick in 1950.
The AG-1 might be considered as the mother of all modern crop-sprayers in the world. The prototype Model S-1
(N5385N c/n 1001) was extensively tested in South America before the improved Model S-2 reached production.
Production of the S-2B by Snow Aeronautical Company started in 1958. North American Rockwell acquired the
design and production-rights of the S-2 series in November 1965. The S-2R was marketed by the growing Aero
Commander Division of Rockwell. In Marh 1970, Rockwell moved the entire product line from Olney,Texas to Albany,
Georgia. In November 1977, Rockwell sold the productionrights for their agriculture aircraft to Ayres Corporation.
Ayres Corporation subsequently sold the aircraft in many variants with different engines, including the Pratt
& Whitney PT6 and Garrett turbine engines. Ayres Corporation went bankrupt in 2001. As a restart, the
rights of the Thrush Commander were transferred via Quality Aerospace to the newly established Thrush Aircraft
Incorporated. In the fall of 2019, a new management team implemented a necessary restructuring of the company,
resulting in 113 employees losing their jobs. The now healthy Thrush Aircraft LLC produces and sells the spray
aircraft mainly as fire-fighting aircraft.

In April 1983, the aircraft was seen first as N984SQ at the facilties of Tom van der Meulen at Oostwold Airfield (EHOW).
On 24 May 1991, the 1978-built Ayres S-2R-T331 Turbo Thrush N9486Q was seen at Lelystad airport (EHLE/LEY) in service with Tom van der Meulen / Aero Service. |
