CAA Recommends SORA General Operations Manual for UK Drone Operators

The UK Civil Aviation Authority has released a recommendation that all drone operators working under the Specific Operations Risk Assessment (SORA) framework maintain a General Operations Manual (GOM). Published via SUAS News, the guidance signals a shift toward more formalised documentation for commercial unmanned aircraft operations. For fleet operators, repair customers, and buyers in the pre-owned DJI market, this is a practical development that affects how aircraft are procured, maintained, and resold.

The SORA framework, which is the UK’s adopted method for risk-assessing medium-risk drone flights, already requires operators to submit a safety case. The addition of a recommended GOM structure brings the UK closer to the operational documentation standards seen in manned aviation. While the GOM is not yet mandatory, the CAA’s endorsement means operators who adopt it early may face fewer friction points during renewal inspections or incident investigations. This is especially relevant for enterprise operators flying DJI Matrice 300 RTK, Mavic 3 Enterprise, or other capable platforms under an operational authorisation.

Why a General Operations Manual now

The CAA’s recommendation arrives as SORA become more widely used across Europe and the UK for drone operations that cannot fit within the open category – typically flights over people, near infrastructure, or beyond visual line of sight. According to the source document, the GOM is intended to “comply with CAA recommendations” for UAS operators. It is not a replacement for the safety case, but a complementary document that standardises how operators describe their procedures, crew training, maintenance schedules, and emergency responses.

For fleet managers, this means that any drone intended for SORA-classified work will need to be supported by documented maintenance history and pilot competency records. That requirement has a direct knock-on effect on the second-hand market: a pre-owned DJI drone that comes with a complete maintenance log and original repair documentation will command a premium over one that does not. Operators looking to upgrade their fleet in the coming months should factor in the administrative cost of retrociting historical records for used aircraft purchased without full provenance.

The practical implication for repair customers is equally clear. When sending a drone for professional repair, you should request a detailed work order that includes the replaced part serial numbers, firmware version after repair, and a signed-off check of all flight-critical systems. This documentation can then be filed into the operator’s GOM appendix. Shops that provide such paperwork – like those using genuine OEM spare parts – become more valuable partners in a SORA-compliant fleet.

What this means for drone buyers

If you are purchasing a used drone for commercial work, the GOM recommendation adds a new layer of due diligence. A drone that has been repaired with non-genuine parts or lacks a documented service history may be harder to integrate into a SORA safety case. Inspectors and auditors may ask for evidence of component traceability, especially for flight controllers, motors, and batteries.

Buyers should consider sourcing aircraft from vendors who provide full history reports and who use OEM-pulled parts for repairs. This is where the pre-owned DJI drones market shifts: a well-documented pre-owned unit from a trusted source retains operational value beyond its hardware condition. Similarly, sellers of used fleet equipment should begin collecting logs and repair invoices now, as these will become selling points in a SORA-driven market.

For those planning to trade in an older drone, having a complete file can increase its trade-in valuation. The drone trade-in guide offers a framework for preparing your aircraft for resale under these emerging documentation standards.

Documentation and the pre-owned DJI market

The pre-owned DJI drone market in the UK has been dynamic for years, driven by operators who upgrade every 18–24 months. The CAA’s GOM recommendation adds a new layer of value to well-kept drones. A Mavic 3 Enterprise that has been serviced with genuine OEM spare parts and flown under a documented safety case will be easier for the next operator to fold into their own manual. Conversely, a drone that has been repaired by an unauthorised shop and has no service records may be considered a higher risk for SORA operations, potentially lowering its resale price.

This trend also affects repair decisions. If you are currently operating a drone under SORA, using professional DJI repair services that provide a detailed invoice and parts traceability is not just a maintenance choice – it is a compliance investment. The documentation from each repair can become a section in your GOM appendix, demonstrating to the CAA that your fleet is maintained to a known standard.

Fleet operators should also review their current stock of spare parts. Spare propellers, batteries, and sensors should be logged with purchase dates and batch numbers. In the event of an incident, the CAA may ask to see that critical components were sourced from genuine supply chains. The GOM recommendation effectively makes supply chain transparency a regulatory expectation, even if it is not yet a legal requirement.

Preparing your operation for the GOM standard

So what should an operator do differently today? First, if you do not yet have a written operations manual, consider drafting one using the structure outlined in the UK SORA guidance. Even if your current authorisation does not require it, having the document ready will make renewal applications smoother and show proactive compliance. Second, audit your fleet’s paper trail. For each drone, gather the original purchase invoice, all repair records, firmware update logs, and pilot training certificates. File them in a digital binder organised by aircraft serial number.

Third, when buying additional aircraft, prioritise units that come with full documentation. The price difference between a bare drone and one with a complete history may be modest now, but the GOM recommendation will widen that gap as more operators adopt the manual standard. Fourth, if you are selling used equipment, assemble a due diligence pack for each aircraft. Include the maintenance log, any repair receipts, and a note about which parts are original. This pack turns a pre-owned drone into a compliance-ready asset for the next owner.

Finally, for those using professional DJI repair services, ask your repair partner whether they provide a compliance-grade work order. If they cannot, meaning the output lacks part traceability or signed-off flight tests, you may want to switch providers. The GOM recommendation elevates repair documentation from a nice-to-have to an operational requirement for anyone flying under SORA.

Frequently asked questions about the UK SORA General Operations Manual

Is the General Operations Manual mandatory for UK drone operators?

Reboot Hub analysis: At this stage, the CAA recommends the GOM as best practice for all UK SORA UAS operators. It is not yet a legal requirement, but operators who adopt it may face fewer questions during renewal or incident review. The recommendation is likely to become more formalised over time.

How does the GOM affect the second-hand drone market?

Drones with complete maintenance and repair documentation will be more attractive to commercial buyers operating under SORA. A pre-owned DJI drone that comes with a documented history and genuine parts provenance can be integrated into a new operator’s GOM with minimal friction, preserving its resale value.

What should I include in my operations manual for drone repair records?

For each repair, include the date, component replaced, part serial number, technician name, and a post-repair flight test result. If the repair used OEM genuine spare parts, note that along with the supplier. This information forms a verifiable chain of custody that supports your safety case and demonstrates due diligence to the CAA.
