Action
Final rule.
Summary
We are adopting a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) BR700-715A1-30, BR700-715B1- 30, and BR700-715C1-30 turbofan engines. This AD requires replacement of the low-pressure compressor (LPC) case ice impact panels. This AD was prompted by a report of a partial de-bonding of the LPC case ice impact panels during an engine shop visit. We are issuing this AD to prevent failure of the LPC case ice impact panels, which could result in damage to the engine and loss of control of the airplane.
