Airworthiness Directives; General Electric Company CT58 Series and Former Military T58 Series Turboshaft Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to certain General Electric Company (GE) CT58 series and former military T58 series turboshaft engines. This action requires the removal from service of certain fuel flow divider assemblies, and replacement with serviceable parts. This amendment is prompted by reports of large volumes of fuel leakage from end caps on fuel flow divider assemblies. The actions specified in this AD are intended to prevent fuel flow divider assembly fuel leakage, which could cause an engine fire, leading to an in-flight engine shutdown and forced landing.

Which aircraft AD 2001-12-07 applies to

MakesGeneral Electric
ModelsCT58
Part-conditional — 4050T82G02, 5040T77G02.

Within 120 hours TIS after effective date, check the temperature control assembly serial number mounted on the fuel flow divider assembly; if the first two digits are 95-99 (or SN cannot be determined), replace the entire fuel flow divider assembly (P/N 4050T82G02 or 5040T77G02) per GE Alert SB CT58 73-A0080, dated Feb 13, 2001, to prevent fuel leakage/engine fire.

Whether AD 2001-12-07 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 2001-12-07 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.
