A checklist for a financier taking an international interest in an aircraft object under the Cape Town Convention, and for an irrevocable deregistration and export request authorisation lodged with CASA. It does not cover the Personal Property Securities Register.

## Key facts

- Kind: Checklist. Steps or checks to work through and tick off.
- Practice area: [Aviation, Drones & Space](https://ailawframework.com/precedents/aviation-drones-and-space.md)
- Jurisdictions: Australia, Commonwealth, International / cross-border
- AI level: Yellow. You and the tool draft together, with you directing. You check every statement you rely on.
- Law stated as at: 2026-10-22
- Status: Maintained. Checked on 2026-10-22 against the 2 authorities it cites, for Australia, Commonwealth and International / cross-border.

## When to use it

Use when finance is being taken over an airframe, helicopter or aircraft engine that meets the Cape Town thresholds, or when an IDERA is to be lodged with CASA. Confirm the asset meets the thresholds. A Personal Property Securities Register registration, if one is needed, is a separate step and is not described here.

## Used for these tasks

- [Register the financier’s interests in an aircraft and its engines](https://ailawframework.com/practice/aviation-drones-and-space/register-the-financier-s-interests-in-an-aircraft-and-its-engines.md)

## How AI may be used

AI may compare the aircraft's seat count, payload and engine thrust with the thresholds on the department's page. The lawyer decides whether the Convention applies and what is registered, and a person lodges.

**AI may:**

- Enter seat capacity, payload and thrust from the specification into the threshold table
- List whether an IDERA is in the finance documents and whether CASA's IDERA page has been read
- Keep a Personal Property Securities Register question on the checklist without answering it

**AI must not:**

- Must not state that an international interest has priority
- Must not treat this checklist as a Personal Property Securities Register lodgement
- Must not lodge an IDERA or an international registration

**The lawyer checks:**

- The asset meets a threshold on the department's page, using figures from the specification
- The Convention's application to this debtor, creditor and transaction is decided by the lawyer
- The IDERA, if any, matches CASA's current process
- Any Personal Property Securities Register registration is done from the Personal Property Securities Act and the current AFSA guidance, not from this page

## Authorities
