**RIN 2120–AA64**
**Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Turbofan**  **Engines**

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**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.

**DATES :**  This AD becomes effective May 23, 2014.
**ADDRESSES :**  The Docket Operations office is located at Docket Management Facility, U.S. Department of Transportation, 1200 New Jersey Avenue SE., West Building Ground Floor, Room W12–140, Washington, DC

**SUPPLEMENTARY INFORMATION :** 
Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to the specified products. The NPRM was published in the Federal Register on December 23, 2013 (78 FR 77382). The NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

Partial de-bonding of the low-pressure compressor 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.

To address this potential unsafe condition, RRD issued Alert Non Modification Service Bulletin (NMSB) SB–BR700–72–A900281 to provide instructions for a one-time ice impact panel replacement using an improved repair method.

You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov/#!document Detail;D=FAA-2013-0884-0002.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (78 FR 77382, December 23, 2013).

Conclusion

We reviewed the available data and determined that air safety and the public interest require adopting this AD as proposed.
