Short version: if you spray with a drone in the United States, flying skill is not enough. Dispensing crop protection from the air is its own regulated activity, and Part 137 is the certificate that allows it. Here is what it covers and how it fits with the other rules.
What Part 137 is
Part 137 governs agricultural aircraft operations, which the FAA defines as dispensing economic poisons such as pesticides, or other agricultural materials, from an aircraft. A drone used for spraying is treated as an agricultural aircraft, so the operator needs a Part 137 operating certificate. It is separate from the certificate that lets you fly.
How it fits with the other requirements
Spraying drones usually sit at the intersection of several rules:
- Part 107 for the remote pilot, covered in our Part 107 guide.
- Part 137 for the agricultural operation itself.
- An exemption for aircraft over 55 pounds, which includes many spraying drones.
- EPA and state pesticide rules, including following the product label and, in many states, holding an applicator license.
What getting certified involves
In broad terms, you apply to the FAA for a Part 137 certificate, show that you and your operation can dispense safely, and designate qualified personnel. The exact steps and any knowledge checks depend on your operation and your aircraft weight. Plan for this early, because the paperwork and approvals can take longer than buying the drone.
Why it matters before you buy
Operators sometimes purchase a large spraying drone and only then discover the certification path. Knowing the requirements first lets you choose an aircraft and a timeline that fit, rather than owning equipment you cannot legally fly for the job. It also reassures the farms and contractors who hire you that you operate by the book.
