Abstract
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.
