Spray drone pilots need a Part 137 certification from the FAA to stay compliant with federal regulations governing the use of drones for agricultural spraying. Part 137 outlines the operational requirements for aircraft used in agricultural applications, including the safe handling of pesticides and other chemicals. This certification ensures that pilots are trained to operate drones in a manner that meets FAA safety standards, protecting both the environment and public safety. Without a Part 137, pilots are not legally permitted to conduct commercial spraying operations, which could result in penalties, fines, or a loss of operational authority. By obtaining a Part 137, spray drone operators demonstrate their commitment to safe, compliant, and effective agricultural practices, while also gaining the legal framework needed to operate within the growing drone industry.
