Airworthiness Directive 2021-14-19
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 a review of investigative findings from 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 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 with a part eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2021-14-19 applies to
Applies only to engines with an installed HPT 1st-stage disk P/N 2A5001 (S/N listed in Table 1 of P&W SI No. 112F-21, dated May 24, 2021) or HPT 2nd-stage disk P/N 2A4802 (S/N listed in Table 2 of P&W SI No. 112F-21, or Table 1 of P&W SI No. 114F-21, dated May 24, 2021).
Whether AD 2021-14-19 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.
