Airworthiness Directive · Amendment 39-16243 · International Aero Engines (IAE) V2500-A1, V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, and V2533-A5 Turbofan Engines
International Aero Engines (IAE) V2500-A1, V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, and V2533-A5 Turbofan Engines
This AD applies to International Aero Engines (IAE) V2500-A1, V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, and V2533-A5 turbofan engines with high-pressure (HP) compressor stage 3-8 drums, part numbers (P/Ns) 6A4900, 6A5467, 6A6473, 6A7383, 6A7384, 6A7385, and 6A7401, installed. These engines are installed on, but not limited to, Airbus A319, A320, and A321 series airplanes and Boeing MD-90 airplanes.
The FAA is adopting a new airworthiness directive (AD) for IAE V2500-A1, V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, and V2533-A5 turbofan engines. This AD requires a onetime fluorescent penetrant inspection of certain vortex reducers for cracks. This AD results from reports of fractured vortex reducers found at shop visits. We are issuing this AD to inspect for cracks in the vortex reducer. Cracks in the vortex reducer could result in an uncontained failure of the high-pressure (HP) compressor stage 3-8 drum and subsequent damage to the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
Fluorescent penetrant inspect the vortex reducer for cracks when the HPC stage 3-8 drum has between 3,000 and 13,500 cycles-since-new (CSN) if all of the following conditions also apply:
(1) The HPC stage 3-8 drum has ever operated in an engine at the V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, or V2533-A5 thrust ratings,
(2) The vortex reducer had cycles accumulated on it when mated with the HPC stage 3-8 drum, and
(3) The HPC stage 3-8 drum had fewer than 3,000 CSN when mated to the vortex reducer.
(g) If the vortex reducer is cracked, remove both the vortex reducer and the HPC stage 3-8 drum from service.
(h) After the effective date of this AD, do not return to service any HPC stage 3-8 drum that was removed as specified in paragraph (g) 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.
