Applicability*9
This AD applies to International Aero Engines AG (IAE AG) Model V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, V2531-E5, and V2533-A5 engines.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
(1) Within 90 days after the effective date of this AD, revise paragraph B.1 of the Maintenance Scheduling section in the airworthiness limitations section (ALS) of the Instructions for Continued Airworthiness (ICA) located in the applicable existing Time Limits Manual (TLM), as listed in paragraphs (g)(1)(i) through (iii) of this AD, by incorporating the information specified in table 1 to paragraph (g) of this AD: (i) Part Number (P/N) 2A4408, TASK 05-10-00-990-000-B00 Instructions For Continued Airworthiness (V2500-A5); (ii) P/N 2A4417, TASK 05-10-00-990-000 Instructions For Continued Airworthiness (V2500-D5); (iii) P/N 2A4384, TASK 05-10-00-990-000-A00 Instructions For Continued Airworthiness (V2500-E5). (2) For air carrier operations, within 90 days after the effective date of this AD, revise the existing approved maintenance or inspection program, as applicable, by incorporating the information specified in table 1 to paragraph (g) of this AD, as applicable. Table 1 to Paragraph (g)—ALS Additional Inspections Part nomenclature Part No. Inspection (engine manual reference) HPT Stage 1 Hub 2A5001 TASK 72-45-11-200-006. HPT Stage 2 Hub 2A4802 TASK 72-45-31-200-009.
Unsafe condition
This AD was prompted by further analysis of an event involving an IAE AG model V2533-A5 engines that experienced an uncontained high-pressure turbine (HPT) 1st-stage hub failure that resulted in high-energy debris penetrating the engine cowling. The FAA is issuing this AD to prevent failure of the HPT 1st-stage hub and HPT 2nd-stage hub. The unsafe condition, if not addressed, could result in an uncontained hub failure, release of high-energy debris, damage to the engine, damage to the airplane, and loss of the airplane.
Affected ADs
None.

You just looked this one up by hand
TrackAD holds all 12,278 of them and matches them against the aircraft you actually look after — airframe, engine, propeller and appliances in one pass — then works out what falls due and when.
- Bring your existing list in from a spreadsheet Paste the rows straight out of Excel. Headers like C/W Date and N/A are read for you.
- A copy that works when this does not One file. No internet, no login, no this software running. For the morning something has to be produced and the computer is not cooperating.
- $5 a month, or $50 a year Up to 50 aircraft on either.
