## Abstract

The FAA is adopting a new airworthiness directive (AD) for General Electric Company (GE) CF6-80E1 series turbofan engines with certain part number (P/N) compressor rear frames (CRFs) installed. This AD requires revisions to the Airworthiness Limitations Section (ALS) of the manufacturer's Instructions for Continued Airworthiness (ICA) and air carrier's approved Continued Airworthiness Maintenance Programs (CAMP) to include initial and repetitive eddy current inspections (ECIs) or fluorescent penetrant inspections (FPIs) of the affected CRFs. This AD results from the need to require enhanced inspections of the CF6-80E1 series engine CRFs for cracks. We are issuing this AD to prevent rupture of the CRF, which could result in an under-cowl engine fire.
