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 a completely new high-lift wing 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.
