## 🛠️ Service Notes

-   If your records show 3825457, note that fan ring 3827612 also lists that number among the ones it consolidates - check whether your engine needs the full shroud or only the ring
-   Fan shroud 3827830 at 17.75 kg is the other TAD shroud here and covers 8 applications against this one's 2, so confirm the engine designation
