What it is
14 CFR Part 137 governs agricultural aircraft operations, including drones used to dispense or spray economic poisons, plant nourishment, soil treatment, pest control or forest-preservation materials.
The typical UAS path is aircraft registration, then any required exemptions, then the Agricultural Aircraft Operator Certificate (AAOC) application. Many aircraft of 55 pounds or more require Section 44807 relief, alongside exemptions from applicable Part 107, 91, 61 or 137 provisions as needed for the operation.
After the exemption is issued, complete FAA Form 8710-3 and submit it with the exemption number to UAS137Certificates@faa.gov. The applicant name must match the Part 137 exemption holder. The streamlined UAS process no longer requires applicants to submit documents to their local FSDO.
For UAS, the §137.19(e) knowledge and skill tests may be self-administered. Document satisfactory completion and provide it to the FAA upon request. Applicable pilot-in-command requirements still apply.
State pesticide and aerial applicator licensing may be separately required. These licenses are not the FAA Part 137 certificate and remain the customer's responsibility.
Who needs it
Agricultural drone operators planning dispensing or spraying operations who need an organized certificate application after their prerequisite exemptions are issued.
