Mechanic to mechanic: This is a reference index, not a sign-off. AD text is excerpted from the Federal Register (the system of record) for convenience — if this excerpt and the official AD disagree, the official AD governs. We never infer due dates or intervals from AD text; your A&P / IA must read the full AD and your aircraft records to determine applicability and compliance.

Per-aircraft compliance — “what’s due on your airplane” — lives in the Logbook.
