Airworthiness Directive 97-22-14
one-timeAirworthiness Directives; General Electric Company CF6-50 and - 80C2 Series Turbofan Engines
What this AD requires
This amendment adopts a new airworthiness directive (AD) that is applicable to General Electric Company (GE) CF6-50 and -80C2 series turbofan engines. This action requires removal from service of defective high pressure compressor rotor (HPCR) stage 3-9 spools, and replacement with serviceable parts. This amendment is prompted by a report of an uncontained failure of an HPCR stage 3-9 spool installed on a GE model CF6-80C2 turbofan engine. The actions specified in this AD are intended to prevent failure of the HPCR stage 3-9 spool, which can result in an uncontained engine failure and damage to the aircraft.
Which aircraft AD 97-22-14 applies to
Installed on but not limited to Boeing 767 and 747 series, McDonnell Douglas DC-10 and MD-11, and Airbus Industries A300 and A310 series aircraft.
Whether AD 97-22-14 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:
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.
