Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines
Published . Updated .
The FAA is adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model RB211 Trent 768-60, 772-60, and 772B-60 engines. This AD was prompted by a report that a batch of low-pressure compressor (LPC) blades were exposed to a non- conforming repair and are more prone to cracking due to a deviation from the approved blade configuration design. This AD requires removal from service of the affected LPC blades and replacement with a serviceable part. The FAA is issuing this AD to address the unsafe condition on these products.
