Airworthiness Directives; General Electric Aircraft Engines CF34 Series Turbofan Engines

What this AD requires

This amendment revises an existing airworthiness directive (AD), that is applicable to General Electric Aircraft Engines (GE) CF34 series turbofan engines. That AD currently requires: (1) Replacement of Buna-N O-rings with Viton O-rings; or (2) A new location of the vent groove on the MFC mounting flange; or (3) Installation of an MFC with improved overspeed protection.

ModelsCF34-1A, CF34-3A, CF34-3A1, CF34-3A2, CF34-3B, CF34-3B1, CF34

Whether AD 00-3336 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 00-3336 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.
