Airworthiness Directive 2021-11-15
one-timeAirworthiness Directives; International Aero Engines AG Turbofan Engines
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain International Aero Engines AG (IAE) V2500 model turbofan engines. This AD was prompted by an analysis performed by the manufacturer after an event involving an uncontained failure of a high- pressure turbine (HPT) 1st-stage disk that resulted in high-energy debris penetrating the engine cowling. This AD requires the performance of an ultrasonic inspection (USI) of the HPT 1st-stage disk and HPT 2nd-stage disk and, depending on the results of the inspections, replacement of the HPT 1st-stage disk or HPT 2nd-stage disk. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2021-11-15 applies to
Applies only to engines with an HPT 1st-stage disk, P/N 2A5001, with a serial number listed in IAE NMSB V2500-ENG-72-0713 Revision 1 or NMSB V2500-E5-72-0015, installed; and/or an HPT 2nd-stage disk, P/N 2A4802, with a serial number listed in Table 2 of the same NMSBs, installed.
Whether AD 2021-11-15 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:
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.
