## Key facts

| Fact | Value |
| --- | --- |
| Practice area | [Aviation, Drones & Space](https://ailawframework.com/practice/aviation-drones-and-space.md) |
| Human involvement | Green: AI drafts, lawyer checks |
| How AI is used | From the security agreement or lease, the aircraft and engine specifications and the parties’ registry details, build the registration schedule: each airframe, engine and helicopter by manufacturer, model and serial number, the PPSR registrations to be made with their collateral class and serial numbers, and the International Registry registrations and consents required from each party, and flag any serial number that differs between documents. |
| What the lawyer must review | The lawyer confirms which interests are registrable on each register, checks each serial number against the aircraft’s own records, confirms the parties have the registry access and consents needed, and confirms each registration was made correctly before funds are released. |

## Checking plan

**Lawyer review required**

The responsible lawyer reviews the work against the instructions, sources and intended use.

- What the AI does: From the security agreement or lease, the aircraft and engine specifications and the parties’ registry details, build the registration schedule: each airframe, engine and helicopter by manufacturer, model and serial number, the PPSR registrations to be made with their collateral class and serial numbers, and the International Registry registrations and consents required from each party, and flag any serial number that differs between documents.
- What the lawyer does: The lawyer confirms which interests are registrable on each register, checks each serial number against the aircraft’s own records, confirms the parties have the registry access and consents needed, and confirms each registration was made correctly before funds are released.
- Who reviews: Responsible lawyer with competence in the matter
- Basis: Practical workflow informed by the linked primary sources; the traffic light and working checks are editorial guidance, not a court classification.
- Why: The level reflects what the work is, the consequence of an error, and how much of the output the lawyer must independently re-derive.

## Checks the lawyer makes

1. Check each serial number against the manufacturer’s plate data or the aircraft’s records, not only the contract.
2. Confirm engines are registered separately from the airframe where each is registrable collateral.
3. Search both registers after registration and keep the search results with the closing set.

## Notes

- These are suggested working checks. Confirm the required checking with the responsible lawyer before work starts; the checking approach does not establish permission to use AI.
