Abstract
The FAA is adopting a new airworthiness directive (AD) for certain CFM International, S.A. (CFM) LEAP-1A model turbofan engines. This AD was prompted by a report of a manufacturing quality escape found during an inspection of a high-pressure turbine (HPT) case. This AD requires the removal from service of the affected HPT case. The FAA is issuing this AD to address the unsafe condition on these products.
