A proposal is not in force. If adopted, it becomes an AD, usually with changes. Only the Federal Register edition is official.

Summary

We propose to supersede airworthiness directive (AD) 2013-11- 13 that applies to all Rolls-Royce plc (RR) Viper Mk. 601-22 turbojet engines. Since we issued AD 2013-11-13, RR determined that additional parts for the RR Viper Mk. 601-22 as well as additional engine models are affected. This proposed AD would add two new engine models and additional engine parts to the applicability. We are proposing 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.

The resulting AD
