American Airmotive NA-75
The American Airmotive NA-75 was an agricultural aircraft marketed in the United States in the 1960s, created by remanufacturing military surplus Boeing Stearman trainers. The aircraft were fitted with completely new, high-lift wings, and one of the cockpits was replaced by a chemical hopper. As of 1980, over 200 Stearmans had been modified in this way, either by American Airmotive directly, or via conversion kits that the company sold.
