Airworthiness Directives; Honeywell International Inc. Turbofan Engines

概要

We are adopting a new airworthiness directive (AD) for certain Honeywell International Inc. (Honeywell) AS907-1-1A turbofan engines. This AD was prompted by reports of loss of power due to failure of the second stage low-pressure turbine (LPT2) blade. This AD requires a one- time inspection of the LPT2 blades and, if the blades fail the inspection, the replacement of the blades with a part eligible for installation. We are issuing this AD to address the unsafe condition on these products.
