Is AD 2013-02-06 a recurring Airworthiness Directive?

Yes — AD 2013-02-06 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2013-02-06 apply to?

AD 2013-02-06 applies to Engine Alliance — models GP7270, GP7277. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Engine Alliance Turbofan Engines

What this AD requires

We are adopting a new airworthiness directive (AD) for all Engine Alliance GP7270 and GP7277 turbofan engines. This AD requires initial and repetitive borescope inspections and removal from service before further flight if one or more burn holes are detected, in certain high-pressure turbine (HPT) stage 2 nozzles. This AD also requires mandatory removal from service of these HPT stage 2 nozzles at the next engine shop visit. This AD was prompted by a report received of inadequate cooling of the HPT stage 2 nozzle, leading to damage to the HPT stage 2 nozzle, burn-through of the turbine case, and engine shutdown. We are issuing this AD to prevent HPT stage 2 nozzle failure, leading to uncontrolled fire, engine shutdown, 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 — 2101M24G01, 2101M24G02, 2101M24G03.

Applies only to engines with a high-pressure turbine (HPT) stage 2 nozzle, P/N 2101M24G01, 2101M24G02, or 2101M24G03, installed.

Whether AD 2013-02-06 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 2013-02-06 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.
