Airworthiness Directive · Amendment 39-17829 · Rolls-Royce Deutschland Ltd & Co KG Turbofan Engines
Rolls-Royce Deutschland Ltd & Co KG Turbofan Engines
This AD applies to all Rolls-Royce Deutschland Ltd & Co KG (RRD) BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 turbofan engines.
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.
Unless already done, after the effective date of this AD, at the next engine shop visit or within 12,500 engine flight cycles since the last shop visit, whichever occurs first, replace the four LPC ice impact panels with panels eligible for installation.
(1) For the purposes of this AD, an “engine shop visit” is the induction of an engine into the shop for maintenance involving the separation of pairs of major mating engine flanges. The separation of engine flanges solely for the purpose of transportation without subsequent engine maintenance does not constitute an engine shop visit.
(2) For the purposes of this AD, a panel that is “eligible for installation” is a new LPC impact panel or one that has been repaired using RRD Alert Non-Modification Service Bulletin (NMSB) No. ALERT SB-BR700-72-A900281, dated July 1, 2013.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
