Tracking ADs for client aircraft

The AD Tracking section gives you a batch wizard for recording a client aircraft's Airworthiness Directive list — useful when you're working an annual or bringing a new client's AD history into TachMinder. Confirmed ADs are written to the aircraft's AD compliance records, visible to both you and the owner.

How the batch wizard works

1. 1

   Pick the aircraft

   Choose one of your actively linked client aircraft. The wizard also shows you which ADs are already tracked for that aircraft, so you don't re-enter them.
2. 2

   Enter AD numbers

   Enter AD numbers one per line, up to 50 at a time — typed or pasted straight from your AD list.
3. 3

   Review the matches

   TachMinder matches each number against its AD catalog. Review each match, confirm applicability, and confirm recurrence details before anything is written.
4. 4

   Commit the batch

   Committed ADs become part of the aircraft's AD compliance records — the same records the owner sees on their side.

When the catalog disagrees with you

If the catalog flags an AD as possibly not applicable to this specific aircraft, the wizard makes you resolve the mismatch before you can commit. You have two options:

• Override. You record that you, the certificated mechanic, confirm the AD applies. Your applicability call is authoritative — the catalog's flag is a prompt, not a veto — and the override is acknowledged explicitly so the record shows it was your determination.
• Remove it from the batch. If the flag is right and the AD doesn't apply, drop it before committing.

Either way, a possibly-inapplicable AD is never silently written to the aircraft's records.

Recurrence clocks are always explicit

For recurring ADs, the wizard never records a vague "hours." Every recurrence is tied to an explicit clock: calendar months, engine hours, propeller hours, airframe hours, or cycles. That precision is what lets next-due tracking work correctly later — see How next-due dates work and The five AD compliance states.

The FAA is the authority — TachMinder is the record

Applicability and intervals must be verified against the FAA's AD database at drs.faa.gov. TachMinder records what you, the mechanic, confirm — it is not a substitute for the FAA source, and it does not determine applicability for you. Treat the catalog match as a starting point and the FAA database as the final word.
