Is AD 2013-17-07 a recurring Airworthiness Directive?

Yes — AD 2013-17-07 requires a repetitive inspection every 2 months. Next-due depends on the aircraft's time in service.

Airworthiness Directive 2013-17-07

Q: Which aircraft does AD 2013-17-07 apply to?

AD 2013-17-07 applies to General Electric Company — models GE90-76B, GE90-85B, GE90-90B, GE90-94B, GE90-110B1, GE90-115B, GE90. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; General Electric Company Turbofan Engines

What this AD requires

We are adopting a new airworthiness directive (AD) for certain General Electric Company (GE) GE90-76B, -85B, -90B, -94B, -110B1, and - 115B turbofan engines. This AD was prompted by multiple reports of distress of certain stage 1 high-pressure turbine (HPT) stator shrouds due to accelerated corrosion and oxidation, including one engine in- flight shutdown (IFSD) caused by failure of the HPT stator shrouds. This AD requires initial and repetitive on-wing 360-degree borescope inspections (BSIs) for corrosion and oxidation of stage 1 HPT stator shrouds. If a shroud is found to be distressed, this AD requires reinspection at a reduced interval or removal from service before further flight. We are issuing this AD to prevent failure of stage 1 HPT stator shrouds, resulting in an IFSD of one or more engines, loss of thrust control, and damage to the airplane.

Repetitive inspection. Re-inspect every 2 months. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Part-conditional — 1847M52P14, 1847M52P16.

Applies to GE90-76B, -85B, -90B, and -94B turbofan engines with stage 1 HPT stator shroud P/N 1847M52P14 installed; and to GE90-110B1 and -115B turbofan engines with stage 1 HPT stator shroud P/N 1847M52P16 installed.

Whether AD 2013-17-07 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.

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.
