Airworthiness Directives; General Electric Aircraft Engines CF700 Series Turbofan Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to General Electric Aircraft Engines CF700 series turbofan engines, that requires replacement of existing fan guards with new, improved fan guards. This amendment is prompted by a report of uncontained fan blades which separated from the engine during an overspeed. The actions specified by this AD are intended to prevent an overspeed of the aft fan disk from resulting in an uncontained engine failure and damage to the aircraft.

Whether AD 99-13-10 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 99-13-10 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.
