## Checking plan

**Source-by-source verification**

Trace relied-on content to independent sources and check for relevant material the output has missed.

- What the AI does: From the aircraft details and the party the lawyer names, set out whether the airframe or helicopter meets the Cape Town thresholds stated on the CASA page, which of forms 1538, 1539, 1540, 1541 or 1542 matches the step, and who must sign it. The tool does not complete or lodge the form.
- What the lawyer does: The lawyer decides whether an IDERA or a certified designee confirmation letter is available, completes the correct original form, and deals with the consequences of deregistration.
- 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 the airframe or helicopter against the Cape Town thresholds on the CASA page before treating an IDERA as available.
2. Confirm the registration holder, authorised party or certified designee is the person the chosen form requires, and that an original is used where the page requires one.
3. If deregistration is sought, confirm a recorded certified designee letter means the designee must submit form 1542, and record that deregistration removes the certificate of airworthiness.

## 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.
