Airworthiness Directives; Daher Aerospace (Type Certificate Previously Held by SOCATA) Airplanes

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Daher Aerospace (type certificate previously held by SOCATA) (Daher) Model TBM 700 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The unsafe condition that is the subject of the MCAI is ice accumulation on the oil cooler air inlet duct fin. This AD requires modifying the oil cooler air induction duct. The FAA is issuing this AD to address the unsafe condition on these products.

Applies only if an oil cooler air induction duct of the listed part numbers is installed; may have been installed per modification 70-0435-79, Daher Aerospace Service Bulletin SB 70-231 Revision 1 (July 2018), or Daher Aerospace Service Bulletin SB 70-219 Revision 2 (July 18, 2018).

Whether AD 2021-25-10 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 2021-25-10 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
