Plain English Summary

5/10 complexity

This Airworthiness Directive requires removal and bans re‑installation of specified No.4 bearing oil‑system parts (listed by part number) from certain IAE V2500 engine variants. Operators, maintenance organisations and parts suppliers must remove the listed components at the next shop visit according to the AD’s deadlines. The Civil Aviation Safety Authority enforces compliance; affected businesses bear labour, scheduling and parts‑tracking costs. The AD accepts prior compliance with IAE Service Bulletin V2500‑ENG‑72‑0541 Revision 4 as meeting its requirements.

What it does

This instrument is an Airworthiness Directive (AD) directed at International Aero Engines (IAE) V2500 series turbofan engines. Mechanically it requires physical removal of specific oil-system and HPT/LPT sealing parts identified by part number. The AD is structured as four operative requirements:

Requirement 1: For V2500-A1 engines, “remove the parts listed by P/N in the following Table 1 of this AD,” with removal instruction reference to the ATA chapter of the IAE V2500-A1 engine manual (E-V2500-1IA). Table 1 then enumerates multiple P/Ns and nomenclatures (for example P/N 2A0367-01, 2A2873-01, 2A0830-01 and many others) covering tubes, scavenge tubes, seal assemblies, support assemblies, ducts and metering plugs (see Table 1 heading and rows). The AD states “For V2500-A1 engines, remove the parts listed by P/N in the following Table 1 of this AD.” (source: Requirement 1 / Table 1).
Requirement 2: For V2522-A5, V2524-A5, V2527-A5, V2527E-A5, V2527M-A5, V2530-A5, and V2533-A5 engines, “remove the parts listed by P/N in the following Table 2 of this AD,” again pointing to the IAE V2500-A5 engine manual (E‑V2500‑1IA) for removal information, and listing many P/Ns in Table 2. The AD includes a carve‑out: for those A5 variants equipped with HPT stage 1 rotor assembly P/Ns 2A9521-002 or 2A9621-002, the HPT hub metering plug P/N 2A3182 “does not need to be removed.” (source: Requirement 2 / Table 2 and subsequent paragraph).
Requirement 3: For V2525-D5 and V2528-D5 engines, “remove the parts listed by P/N in the following Table 3 of this AD” and refer to the IAE V2500‑D5 engine manual (E‑V2500‑3IA) for removal instructions. Table 3 lists a set of P/Ns and nomenclatures comparable to the other tables. There is the same metering plug carve‑out for those engines when fitted with HPT rotor assemblies P/Ns 2A9521-002 or 2A9621-002: P/N 2A3182 “does not need to be removed.” (source: Requirement 3 / Table 3 and paragraph).
