Abstract
We are adopting a new airworthiness directive (AD) for certain Rolls-Royce Corporation (RRC) AE 3007A and AE 3007C model turbofan engines. This AD was prompted by an updated analysis that lowered the life limit of fan wheels installed on the affected engines. This AD requires removal of the affected fan wheel at new, lower life limits. We are issuing this AD to address the unsafe condition on these products.
