Airworthiness Directive · Amendment 39-14367 · General Electric Company (GE) CF6-80E1A1, -80E1A2, -80E1A3, -80E1A4, and -80E1A4/B Turbofan Engines
General Electric Company (GE) CF6-80E1A1, -80E1A2, -80E1A3, -80E1A4, and -80E1A4/B Turbofan Engines
Superseded. A later AD replaced this one: AD 2020-13-08. Comply with the one in force.
This AD applies to General Electric Company (GE) CF6-80E1A1, -80E1A2, -80E1A3, --80E1A4, and -80E1A4/B turbofan engines. These engines are installed on, but not limited to, Airbus Industrie A330 series airplanes.
The FAA is adopting a new airworthiness directive (AD) for General Electric Company (GE) CF6-80E1A1, -80E1A2, -80E1A3, -80E1A4, and -80E1A4/B turbofan engines. This AD requires initial and repetitive fluorescent-penetrant inspections (FPI) of certain areas of high pressure compressor (HPC) cases, part number (P/N) 1509M97G07 and P/N 2083M69G03. This AD results from the discovery that HPC cases, P/N 1509M97G07 and P/N 2083M69G03, were inadvertently left out of the Airworthiness Limitations Section (ALS), Chapter 05-21-02, of GE Engine Manual, GEK 99376, Revision 17. We are issuing this AD to prevent failure of the HPC case aft mount flange, due to cracking.
You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
For HPC cases, P/N 1509M97G07 and P/N 2083M69G03, perform an initial fluorescent-penetrant inspection (FPI) of circumferential flange spotfaces at the first hole in the aft flange above and below each horizontal split line flange, at or before reaching 7,300 cycles-since-new. See Figure 1 of this AD for reference. Information on inspecting these areas can be found in the ALS of GE Engine Manual GEK 99376, Revision 19, dated August 15, 2005.
Perform repetitive FPI of circumferential flange spotfaces at the first hole in the aft flange above and below each horizontal split line flange, within 3,700 cycles-since-last-inspection. See Figure 1 of this AD for reference. Information on inspecting these areas can be found in the ALS of GE Engine Manual GEK 99376, Revision 19, dated August 15, 2005.
