Oregon has the most demanding aerial licensing pathway in the West. The Aerial Pesticide Applicator (APA) license is a separate add-on on top of the underlying applicator license, requiring the Core exam, a use-category exam and the APA exam. Before applying for the APA, operators must document 50 hours of flight experience applying pesticides or supervised training, one of the highest flight-hour barriers in the US. Critically, Oregon law prohibits applying any pesticide by aircraft without an APA license even under the direct supervision of a licensed APA holder.
Oregon Forest Practices Act establishes 60-foot buffer zones from fish-bearing or drinking water streams for non-helicopter aerial applications. Renewal is 5-year with 10 aerial credits required. No blanket reciprocity, aerial reciprocity is handled case-by-case.
