Airworthiness Directives; CFM International CFM56-5B/2P Series Turbofan Engines

What this AD requires

This document makes a correction to Airworthiness Directive (AD) 98-02-04 applicable to CFM International (CFMI) CFM56-5B/2P series turbofan engines that was published in the Federal Register on January 21, 1998 (63 FR 3031). The low pressure turbine (LPT) case part number (P/N) in the compliance section is incorrect. This document corrects that P/N. In all other respects, the original document remains the same.

Whether AD 98-25005 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:

Method of complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 98-25005 complied with on your aircraft?

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.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
