Is AD 2016-02-04 a recurring Airworthiness Directive?

Yes — AD 2016-02-04 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2016-02-04 apply to?

AD 2016-02-04 applies to Cfm International — models 5B, CFM56. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; CFM International S.A. Turbofan Engines

What this AD requires

We are adopting a new airworthiness directive (AD) for certain CFM International S.A. (CFM) CFM56-5B series turbofan engines. This AD was prompted by a corrected lifing analysis by the engine manufacturer that shows the need to identify an initial and repetitive inspection threshold for certain part number (P/N) turbine rear frames (TRFs). This AD requires initial and repetitive inspections of certain P/N TRFs on the low-pressure turbine (LPT) frame assembly. We are issuing this AD to prevent failure of the TRF on the LPT frame assembly, which could lead to engine separation, damage to the engine, and damage to the airplane.

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.

Part-conditional — 338-102-907-0, 338-102-908-0.

Applies only to engines with turbine rear frame (TRF), P/N 338-102-907-0 or P/N 338-102-908-0, installed.

Whether AD 2016-02-04 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 2016-02-04 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.
