Airworthiness Directives; CFM International, S.A. CFM56-2-C, -3 Series, and -5 Series Turbofan Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD), that applies to CFM International, S.A., CFM56-2-C, -3 series, and -5 series turbofan engines. This amendment requires removing from service main fuel pumps with bronze gear-stage bearings and installing main fuel pumps with bi-metal, aluminum/bronze bearings. This amendment results from several reports of main fuel pump bronze bearing failures. We are issuing this AD to prevent main fuel pump bearing failures resulting in fuel nozzle clogging, low pressure turbine (LPT) case burn-through, and damage to the airplane.

Requires removal from service of specific main fuel pump part numbers (which vary by CFM56-2-C, CFM56-3, and CFM56-5 series engine and by which prior service bulletin has been incorporated) and installation of a serviceable pump; exact P/N-to-engine-series/SB mapping is given in AD paragraphs (a)-(d).

Whether AD 2004-10-13 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 compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD 2004-10-13 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.
