Quick reference only — not a compliance record. This list is for research convenience and may be incomplete or out of date. It is not an airworthiness compliance determination. Always verify against the official FAA record, and check directly with the FAA before relying on it. ADs are mandatory; STCs indicate approval for the type (not installation on a specific airframe); SAIBs are advisory.

Supplemental Type Certificates (STCs) approved for the Diamond DA40 type — FAA-approved modifications available for this aircraft family. Approval for the TYPE does not mean a given STC is installed on any individual airframe (that lives in the logbooks/337s).
