Summary

We are superseding airworthiness directive (AD) 2013-11-13 for all Rolls-Royce plc (RR) Viper Mk. 601-22 turbojet engines. AD 2013-11- 13 required reducing the life of certain critical parts. This AD adds two new engine models and additional engine parts to the applicability. This AD was prompted by a determination by RR that additional parts for the RR Viper Mk. 601-22 as well as additional engine models are affected. We are issuing this AD to prevent failure of life-limited parts, which could lead to an uncontained part release, damage to the engine, and damage to the airplane.
