Airworthiness Directive · Amendment 39-14841 · International Aero Engines AG (IAE) V2522-A5, V2524-A5, V2527-A5, V2527E-A5, V2527M-A5, V2530-A5, and V2533-A5 Turbofan Engines
International Aero Engines AG (IAE) V2522-A5, V2524-A5, V2527-A5, V2527E-A5, V2527M-A5, V2530-A5, and V2533-A5 Turbofan Engines
This AD applies to International Aero Engines AG (IAE) V2522-A5, V2524-A5, V2527-A5, V2527E-A5, V2527M-A5, V2530-A5, and V2533-A5 turbofan engines with engine serial numbers V10601 through V11335 inclusive and bearings part number (P/N) 2A1165 installed. These engines are installed on, but not limited to, Airbus Industrie A319, A320, and A321 series airplanes.
The FAA is superseding an existing airworthiness directive (AD) for certain IAE V2522-A5, V2524-A5, V2527-A5, V2527E-A5, V2527M- A5, V2530-A5, and V2533-A5 turbofan engines. That AD currently requires initial and repetitive inspections of the master magnetic chip detector (MCD) or the No. 1, 2, 3 bearing chamber MCD. This AD requires the same MCD inspections. This AD also requires removing certain No. 3 bearings and removing certain high pressure compressure (HPC) stubshaft assemblies as mandatory terminating actions to the repetitive MCD inspections. This AD results from IAE developing a terminating action to the repetitive inspections of the chip detectors, and from expanding the applicability to include additional serial-numbered engines with certain No. 3 bearings installed. We are issuing this AD to prevent failure of the No. 3 bearing, which could result in an in-flight shutdown (IFSD) and smoke in the cockpit and cabin.
You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
For engines listed in Table 1 of Appendix 1 of IAE Service Bulletin (SB) No. V2500-ENG-72-0452, Revision 4, dated September 30, 2005, and that have a No. 3 bearing, P/N 2A1165, installed at new production build, do the following:
(1) Within 125 hours time-in-service (TIS) after the effective date of this AD, inspect the master MCD or the No. 1, 2, 3 bearing chamber MCD.
(2) Thereafter, within 125 hours time-since-last inspection, inspect the master MCD or the No. 1, 2, 3 bearing chamber MCD.
(3) If you find bearing material on the master MCD or No. 1, 2, 3 bearing chamber MCD, remove the engine from service before further flight.
We recommend the inspection of the master MCD or the No. 1, 2, 3 bearing chamber MCD, using paragraphs (f) through (f)(3) of this AD, on all engines installed on the same airplane, not be done by the same individual before the same flight. This is to minimize the chances of maintenance error on multiple engine airplanes.
At the next shop visit, for engines listed in Table 1 of Appendix 1 of IAE SB No. V2500-ENG-72-0452, Revision 4, dated September 30, 2005, that have a serial number (SN) from V10601 through V11335 inclusive, and that have a No. 3 bearing, P/N 2A1165 installed at new production, remove the No. 3 bearing.
(i) After the effective date of this AD, do not install any No. 3 bearing, P/N 2A1165, removed in paragraph (h) of this AD, into any engine.
At the next shop visit, for engines listed in Table 1 of Appendix 1 of IAE SB No. V2500-ENG-72-0452, Revision 4, dated September 30, 2005, that have a SN from V10601 through V11335 inclusive, remove the HPC stubshaft that has a low-energy plasma coating.
Performing the requirements specified in paragraph (h) and (j) of this AD is terminating action to the repetitive MCD inspections specified in paragraphs (f) through (f)(3) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
