Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2013– 0231, dated September 24, 2013 (referred to hereinafter as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Partial de-bonding of the Low Pressure Compressor (LPC) Case Ice Impact Panels was reported during engine shop visit.

This condition, if not corrected, could lead to Ice Impact Panel de-bonding, resulting, in case of an impact event and release of particles, in blockage of the Outlet Guide Vane and consequent potential loss of thrust or reduced fan flutter margin. You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov by searching for and locating it in Docket No. FAA–
2013–0884.

Relevant Service Information

RRD has issued Alert NonModification Service Bulletin No. ALERT SB–BR700–72–A900281, dated July 1, 2013. The service information describes procedures for replacement of the LPC case ice impact panels. FAA’s Determination and Requirements of This Proposed AD

This product has been approved by the aviation authority of Germany, and is approved for operation in the United States. Pursuant to our bilateral agreement with the European Community, EASA has notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. This proposed AD would require replacement of the LPC case ice impact panels. Costs of Compliance

We estimate that this proposed AD affects 232 RRD turbofan engines installed on aircraft of U.S. registry. We also estimate that it would take about 24 hours per engine to comply with this proposed AD. The average labor rate is $85 per hour. Required parts cost about $9,268 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $2,623,456. Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. ‘‘Subtitle VII: Aviation Programs,’’ describes in more detail the scope of the Agency’s authority.

We are issuing this rulemaking under the authority described in ‘‘Subtitle VII, Part A, Subpart III, Section 44701: General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings

We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed above, I certify this proposed regulation:

(1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866,

(2) Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979),

(3) Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction, and

(4) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

**PART 39—AIRWORTHINESS DIRECTIVES** 

■ 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

**§ 39.13 [Amended]**

■ 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): Rolls-Royce Deutschland Ltd & Co KG (Formerly Rolls-Royce Deutschland GmbH, formerly BMW Rolls-Royce GmbH): Docket No. FAA–2013–0884; Directorate Identifier 2013–NE–31–AD.

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) Definition

(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)
