2014-08-05: Low-pressure compressor (LPC) case ice impact panels

Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD): 2014-08-05 Rolls-Royce Deutschland Ltd & Co KG (Type Certificate previously held by Rolls-Royce Deutschland GmbH and BMW Rolls-Royce GmbH): Amendment 39-17829; Docket No. FAA-2013-0884; Directorate Identifier 2013-NE-31-AD. (a) Effective Date This AD becomes effective May 23, 2014. (b) Affected ADs None. (c) Applicability This AD applies to all Rolls-Royce Deutschland Ltd & Co KG (RRD) BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 turbofan engines. (d) Reason This 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. 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. (e) Actions and Compliance 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. (f) Definitions (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. (g) Alternative Methods of Compliance (AMOCs) The Manager, Engine Certification Office, FAA, may approve AMOCs to this AD. Use the procedures found in 14 CFR 39.19 to make your request.
