Airworthiness Directives; Airbus SAS Airplanes

What this AD requires

The FAA is removing Airworthiness Directive (AD) 2025-05-14, which applied to all Airbus SAS Model A350-941 and -1041 airplanes. AD 2025-05-14 required repetitively testing the pre-cooler exchanger (PCE) for air leaks and reporting the results, and, depending on findings, inspecting the thermal blankets for damage and replacing the PCE. The FAA issued AD 2025-05-14 to address PCE leaking air, which could result in thermal blanket damage that, if combined with an independent event of engine fire, could lead to a temporary uncontrolled fire. Since the FAA issued AD 2025-05-14, a risk re-assessment has shown that the airworthiness concern is not an unsafe condition that warrants an AD. Accordingly, AD 2025-05-14 is removed.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Whether AD 2025-20590 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 compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 2025-20590 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.
