## Abstract

We are adopting a new airworthiness directive (AD) for General Electric Company (GE) CF6-80C2L1F turbofan engines. This AD was prompted by a reduction in the life limit of the affected engines which is the result of a revised operating profile. This AD requires replacement of the high-pressure turbine (HPT) spacer/impeller, part number (P/N) 1539M12P02, at a newer, lower life limit. We are issuing this AD to correct the unsafe condition on these products.
