Drone Spraying Operations and the Law (Part 137 Operations)
Licensing and Certification Requirements for Spray Drone Operations
Operating agricultural spray drones legally comes with a maze of certifications required by the FAA. These include general commercial drone licenses and specific credentials for agricultural aviation. Knowing what's required ahead of time can save operators from unnecessary delays or costly mistakes.
Getting a Part 107 Remote Pilot Certificate
The Part 107 Remote Pilot Certificate is the starting point for all commercial drone operations in the U.S., including agricultural spraying. This certification ensures operators are familiar with airspace regulations, weather considerations, and safety protocols.
To qualify for the Part 107 certificate, you need to:
- Be at least 16 years old
- Have proficiency in English
- Meet fitness standards for safe operations
The process involves passing the FAA's UAG exam, which covers topics like airspace classifications, weather patterns, and emergency protocols. Once you pass, you’ll need to register with the FAA, submit identification documents, and undergo a TSA security background check.
Renewal is required every two years. This can be done by completing recurrent training or retaking the exam, depending on when your certificate expires. After securing the Part 107 certificate, you’ll need an additional license - the AAOC - to legally spray agricultural substances.
The Agricultural Aircraft Operator Certificate (AAOC)
The Agricultural Aircraft Operator Certificate (AAOC), issued under Part 137, is specifically required for applying agricultural substances like pesticides, fertilizers, and seeds by air. This certification ensures operators are legally authorized to perform aerial applications across U.S. farmland.
To apply for the AAOC, operators must:
- Register their drone with the FAA and obtain an N-number, which serves as the drone's official identification in the national airspace.
- Complete FAA Form 8710-3, including your exemption number, proof of drone ownership, business documentation, and a notarized affidavit. Be sure the name on the application matches the exemption holder exactly to avoid delays.
- Conduct training flights to demonstrate proficiency. However, no actual spraying can occur until the Part 137 certificate is issued.
The FAA will also inspect both your drone and operational procedures before granting the certificate. This ensures your equipment meets safety standards and that you understand how to handle agricultural substances properly. These inspections directly tie your registration to operational readiness.
Requirements for Drones Over and Under 55 Pounds
The weight of your drone significantly affects the certification process. The FAA uses 55 pounds as the dividing line, with different rules for drones below and above this threshold.
- Drones under 55 pounds: These follow a simpler certification path, with fewer exemptions and less regulatory oversight. They’re a practical choice for operators managing smaller farms or just starting in agricultural aviation.
- Drones 55 pounds and over: Heavier drones face more stringent regulations, similar to those for manned aircraft. Operators need a Third Class Medical Certificate from an FAA-authorized examiner and must adhere to stricter documentation and safety protocols.
| Drone Weight Category | Medical Certificate | Exemption Complexity | Inspection Requirements |
|---|---|---|---|
| Under 55 pounds | Not required | Standard exemptions | Basic operational review |
| 55 pounds and over | Third Class Medical required | Enhanced exemptions | Comprehensive inspection |
Heavier drones also come with added responsibilities, including periodic safety checks and stricter recordkeeping beyond the standard Part 107 renewal. These requirements reflect the higher risks associated with larger drones carrying heavier chemical payloads.

Exemptions and Compliance Procedures Under FAA Part 137
Operating spray drones under Part 137 involves navigating various exemptions and compliance steps. Since FAA regulations were originally created with manned aircraft in mind, drone operators must request specific exemptions to legally perform agricultural spraying. Knowing the process inside out can help you avoid delays and ensure a smooth path to approval. Here's a closer look at how to secure necessary exemptions and stay compliant.
How to Apply for Section 44807 and Other Exemptions
Section 44807 is an essential exemption that expands the use of drones for agricultural purposes beyond what Part 107 allows. This exemption is tailored to meet the specific needs of agricultural aviation, such as carrying and dispersing substances that are otherwise restricted under standard drone rules.
To start, you'll need a Part 107 certificate and a drone registration (N-number). Your petition for exemption must include a detailed description of your operations, safety measures, and risk management strategies. Clearly explain how you plan to operate safely, including emergency procedures and how you'll comply with aviation and environmental standards. Be prepared to provide thorough documentation showing adherence to local, state, and federal regulations.
For drones weighing over 55 pounds, the exemption process becomes more rigorous. Heavier drones pose greater risks, so your petition must include enhanced safety measures and detailed operational procedures. You'll also need to highlight pilot qualifications and specific training.
Another critical component is maintenance and operational planning. The FAA requires detailed information on how you'll ensure your drone remains airworthy. This includes regular inspections, maintenance schedules, and operational checklists that demonstrate a high standard of safety management.
FAA Compliance for Specific Substances and Operations
After submitting your exemption petition, your operational practices must align with rules governing the substances you intend to use. Some chemicals require additional approval from the EPA and adherence to state-specific regulations. Confirm that all intended substances are cleared for aerial application under relevant laws.
If you're working with hazardous materials, such as certain pesticides, you may need additional exemptions. These operations demand stricter safety protocols, specialized equipment, and sometimes extra pilot training. Note that dispensing live insects is not covered under Part 137, so if you're considering biological pest control, you'll need to explore separate regulatory pathways.
Ensuring compliance with federal aviation rules and state agricultural regulations is crucial. Any lapse in compliance can result in penalties or loss of operating privileges, making careful planning a top priority.
How to Handle FAA Requests for Information (RFI)
During the exemption process, the FAA may request additional details through a Request for Information (RFI). These requests are an opportunity to clarify your operations and provide further safety documentation.
Responding promptly and thoroughly is key. Organize your responses to address each question systematically, and include relevant supporting documentation, such as safety procedures, pilot qualifications, and maintenance logs. Keeping comprehensive records of your operations will make it easier to respond effectively.

Planning Operations and Managing Airspace
Once you've tackled licensing and exemptions, the next step is mastering operational planning and airspace management. These are essential for running spray drone operations legally and efficiently. Operating spray drones isn’t just about taking off and landing - it requires a clear understanding of FAA rules and careful preparation. Getting these basics right can save you from unnecessary costs, delays, and regulatory troubles later on.
Flight Limits and Safety Guidelines
The FAA has specific requirements for drone operations, starting with maintaining a visual line of sight (VLOS). This means you must always be able to see your drone and avoid anything that could block your view.
Altitude matters, too. Spray drones should operate between 10 and 50 feet above the crop canopy and must stay below 400 feet above ground level (AGL) unless you’ve received special authorization.
Speed is another factor. While your exemption may specify certain airspeed limits, keeping your drone at controlled speeds ensures accurate chemical application and gives you enough time to respond to obstacles or emergencies.
Weather plays a big role in flight safety. High winds, for example, can cause chemical drift, making it harder to control your drone and apply treatments effectively. To stay safe, many operators set their own stricter limits for wind speed, visibility, and precipitation - beyond what the FAA requires.
These rules aren’t just about following the law; they’re the foundation for safe and efficient operations.
Airspace Rules for Drone Spraying
Knowing where you can legally fly is key to using spray drones. Most agricultural spraying happens in Class G (uncontrolled) airspace, which doesn’t require prior FAA authorization. This airspace typically extends from the ground up to 700 or 1,200 feet, depending on the location.
If you need to operate in controlled airspace - like Classes B, C, D, or E - you’ll face additional steps. These areas require FAA approval before you can start spraying. You’ll also need to file a Notice to Air Missions (NOTAM), especially if your operation involves flying at night, beyond VLOS, or under other special conditions. Filing a NOTAM involves sharing details like your operation’s location, time, altitude, and purpose through the FAA’s system, ideally at least 24 hours in advance. This process helps notify other airspace users and enhances safety.
Before every flight, check for current NOTAMs and temporary flight restrictions (TFRs) that could affect your operation. Airspace conditions can change quickly due to emergencies, VIP movements, or other aviation activities. Using apps or websites that provide real-time updates on airspace conditions is a reliable way to stay informed.
Using Advanced Drone Features for Compliance
Once you’ve nailed down the operational and airspace basics, advanced drone features can help you stay compliant and improve efficiency. Today’s spray drones come with cutting-edge tools designed to make operations safer and more precise.
GPS systems are at the heart of accurate navigation, helping you stick to defined operational boundaries and achieve precise chemical applications. For even greater accuracy, many drones come equipped with RTK (Real-Time Kinematic) systems, which provide centimeter-level precision. This level of accuracy is especially important for staying within defined flight paths and meeting FAA requirements.
Geofencing technology is another valuable tool. It allows you to set up virtual boundaries before your flight, ensuring your drone avoids restricted zones. If the drone approaches one of these boundaries, it will either stop or return to a safe area automatically.
Modern drones also feature obstacle avoidance systems that use sensors and cameras to detect and steer clear of hazards like trees, power lines, and buildings. Pair this with a thorough pre-flight hazard survey to maximize safety.
Planning tools like real-time mapping and flight planning software make it easier to visualize your operational area. These systems can integrate airspace data, weather updates, and terrain details to help you plan safer missions. Some even sync with NOTAM and TFR databases to provide live airspace updates during your planning process.
Lastly, many drones now include data logging capabilities that automatically record key details like flight paths, altitudes, speeds, and chemical application rates. This data can be a lifesaver during FAA inspections and is also useful for refining your operations over time.
Best Practices and Support Resources
Staying compliant with FAA Part 137 is about more than just knowing the rules - it’s about maintaining thorough records, staying educated, and having access to dependable support. Operators who thrive in the long run are those who develop reliable systems for record-keeping, prioritize proper training, and stay informed about regulatory updates. These habits not only protect your operation from potential enforcement actions but also help you run more efficiently.
Keeping Records and Logbooks
Detailed recordkeeping is your first line of defense during FAA inspections. For every spray operation, document the date, time, location, substances applied, quantities, and the name of the remote pilot. These operational records must be kept for at least 12 months, while maintenance logs often need to be preserved for a longer period.
Maintenance documentation should include a record of all repairs, inspections, and routine servicing - whether it’s something as simple as a battery replacement or a major overhaul. The FAA needs to see that your equipment is consistently airworthy and well-maintained throughout its life.
Many operators are turning to cloud-based recordkeeping for greater security and efficiency. Using standardized templates for flights and maintenance events can ensure your records are complete and consistent. Organizing records by date and drone serial number makes them easy to access during inspections. Some operators also keep physical copies in secure, weatherproof locations as a backup. Regularly reviewing your records can help you spot any gaps or errors before they become compliance issues.
Modern spray drones often come equipped with automated data logging features that simplify the process. These systems can automatically capture flight paths, altitudes, speeds, and chemical application rates, reducing the chance of human error.
Getting Licensing Help and Training
Beyond recordkeeping, proper training is essential for smooth and compliant operations. FAA Part 137 requirements can be complex, especially for newcomers. Seeking professional support can save time and help you avoid costly mistakes during the certification process. It’s important to find resources that address both federal regulations and any state-specific rules that apply to your operations.
Training programs should cover flying techniques, chemical safety, emergency response, and equipment maintenance. They should also teach you how to conduct thorough pre-flight inspections and follow manufacturer maintenance guidelines.
While hands-on experience is crucial, you can conduct training, proficiency, and maintenance flights before obtaining your Part 137 certificate. However, you’re not allowed to perform actual spraying operations until you’re fully certified. Use this preparation time to build your skills and confidence so you’re ready to hit the ground running once certified.
Staying Current on FAA Regulations
Once you’ve established solid recordkeeping and training practices, staying updated on FAA regulations is essential for long-term compliance. The FAA frequently updates its rules, and keeping up with these changes is critical. The agency shares updates through various official channels, and it’s important to have a system in place for monitoring these developments.
Make it a habit to check FAA online resources for authoritative updates on new rules, policy clarifications, and enforcement guidance. Setting up alerts or regularly visiting these resources should be part of your routine compliance strategy.
To simplify complex regulatory updates, many operators turn to industry resources. For instance, Drone Spray Pro offers "Expert Tips, Promos & Updates", which often include news and advice tailored to drone operations.
