Airworthiness Directives; CFM International (CFMI) CFM56-2, -2B, -3, -5B, -5C and -7B Series Turbofan Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to CFMI CFM56-2, -2B, -3, -5B, -5C and -7B series turbofan engines. This action requires limiting engines with certain No. 4 bearings to one on each airplane, replacement of certain No. 4 bearings, and increased frequency of inspections for magnetic particles until the suspect bearing is replaced. This action is prompted by reports of two bearing failures in the fleet since December 2000. The actions specified in this AD are intended to prevent bearing failures, which could cause an engine failure.

Part-conditional — 305-355-717-0.

Applies only to CFM56 engines with a suspect No. 4 bearing (P/N 305-355-717-0) bearing one of the specific bearing/engine serial numbers listed in AD Table 1 (partial list of discrete serials shown in excerpt; table truncated in source, not a contiguous range); limits number of suspect engines to one per airplane within 300 hours TIS.

Whether AD 2001-11-05 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 2001-11-05 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.
