Summary
We are adopting a new airworthiness directive (AD) for certain Honeywell International Inc. (Honeywell) TFE731-4, -4R, -5AR, -5BR, and -5R turbofan engines. This AD was prompted by a report of certain interstage turbine transition (ITT) ducts failing to meet containment capability requirements. This AD requires replacing certain ITT ducts. We are issuing this AD to prevent failure of the ITT duct, which could lead to an uncontained part release, damage to the engine, and damage to the airplane.
