What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain CFM International CFM56 Series turbofan engines. This AD requires replacing certain fuel filters manufactured under parts manufacturer approvals (PMA). This AD results from 12 reports of failed fuel filters. We are issuing this AD to prevent the loss of engine thrust that could result in loss of control during takeoff or landing.

Part-conditional — WF337661, WF337017, 7595983-101, 7588133.

Applies only to engines with these fuel filters installed (Western Filter WF337661 or WF337017; PTI Technologies 7595983-101 or 7588133).

Whether AD 2006-26-01 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 2006-26-01 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.
