Summary
We propose to adopt 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 proposed AD was prompted by a report of a partial de-bonding of the low pressure compressor (LPC) case ice impact panels during an engine shop visit. This proposed AD would require replacement of the LPC case ice impact panels. We are proposing 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.
