Airworthiness Directives; International Aero Engines (IAE) AG V2500-A1, V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, and V2533-A5 Turbofan Engines

What this AD requires

The FAA is superseding an existing airworthiness directive (AD) for IAE AG V2500-A1, V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, and V2533-A5 turbofan engines. That AD currently requires revisions to the Airworthiness Limitations Section (ALS) and Maintenance Scheduling Section (MSS) of the Instructions for Continued Airworthiness (ICA), located in the Time Limits Manual (Chapter 05-10-00) of the Engine Manuals, to include required enhanced inspection of selected critical life-limited parts at each piece-part exposure. This action would add critical life-limited parts for enhanced inspection. This action is prompted by additional focused inspection procedures that have been developed by the manufacturer. The actions specified by this AD are intended to prevent critical life-limited rotating engine part failure, which could result in an uncontained engine failure and damage to the airplane.

ModelsV2500

Requires revising the Airworthiness Limitations Section and Maintenance Scheduling Section of the ICA (Time Limits Manual, per Engine Manuals P/N E-V2500-1IA and E-V2500-3IA) to add mandatory piece-part-level inspections for Group A life-limited rotating parts -- including Fan Disk, Stage 1 HP Turbine Hub, Stage 2 HP Turbine Hub, HPC Stage 3-8 Drum, and HPC Stage 9-12 Drum (all part numbers) -- once a part has accumulated more than 100 cycles since its last piece-part opportunity inspection. No specific V2500 dash designation is given in this excerpt of the applicability text.

Whether AD 2004-12-08 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 2004-12-08 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.
