[4910-13-P] DEPARTMENT OF TRANSPORTATION FederalAviation Administration 14 CFRPart39 [Docket No. FAA-2016-4551; DirectorateIdentifier2016-NE-07-AD; Amendment 39-18576; AD 2016-13-12] 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 certain RollsRoyce Deutschland Ltd & Co KG (RRD) BR700-710A1-10, -710A2-20, and -710C4-11 turbofan engines. This AD requires removing the pawl carrierpivot pins, part number (PIN) BRR17117, from service and replacing them withparts eligible for installation. This AD was prompted by a seized low-pressure turbine (LPT) fuel shut-offpawl carrier caused by corrosion ofthe pawl carrierpivot pin. We are issuing this AD to prevent failure ofthe fuel shut-offmechanism, which could result in uncontained partrelease, damage to the engine, and damage to the airplane. DATES: This AD becomes effective [INSERT DATE 35 DAYS AFTERDATE OF PUBLICATION IN THE FEDERAL REGISTER]. ADDRESSES: For service information identified inthis final rule, contact Rolls-Royce Deutschland Ltd & Co KG, Eschenweg 11, Dahlewitz, 15827 Blankenfelde-Mahlow,Germany; phone: +49 (0) 33 7086 2673; fax: +49 (0) 33 7086 3276.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice ofproposed rulemaking (NPRM) to amend 14 CFRpart 39 by adding an AD that would apply to the specified products. The NPRM was published in 2the FederalRegister on April 1, 2016 (81 FR 18806). The NPRMproposed to correct an unsafe condition for the specified products. The MCAI states: Seizing ofa fuel shut-offmechanismpawl carrier was reported. The subsequent investigation determined that corrosion ofthe pawl carrierpivotpin

### PIN BRR17117, was the failure cause. This condition, ifnot corrected, could lead to loss ofthe fuel shutoffmechanism functionality and loss ofthe engine over-speed protection, possibly resulting in release ofhigh-energy debris, with consequent damage to, and/orreduced control ofthe airplane. You may obtain further information by examining the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating DocketNo. FAA-2016-4551. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (81 FR 18806, April1, 2016). Conclusion We reviewed the available data and determined that air safety and the public interest require adopting this AD as proposed. Related Service Information RRD has issued Alert Service Bulletin (ASB) BR 700-72-A101523, Revision 3, dated December 10, 2015. The service information describes procedures for replacing the pawl carrierpivotpins. This service information is reasonably available because the interestedparties have access to it through their normal course ofbusiness orby the

means identified inthe ADDRESSES section.

### Costs ofCompliance We estimate thatthis AD affects 4 engines installed on airplanes ofU.S. registry. We also estimate that it will take about 3 hours perengine to comply withthis AD. The average labor rate is $85 perhour. Required parts cost about $860 perengine. Basedon these figures, we estimate the cost ofthis AD on U.S. operators to be $4,460. Authority for This Rulemaking Title 49 ofthe United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority ofthe FAA Administrator. "Subtitle VII: Aviation Programs," describes in more detail the scope ofthe Agency's authority. We are issuing this rulemaking underthe authority described in "Subtitle VII, Part A, Subpart III, Section44701: General requirements." Underthat section, Congress charges the FAA withpromoting safe flight ofcivil aircraft in air commerce by prescribing regulations for practices, methods, andprocedures the Administrator finds necessary for safety in air commerce. This regulation is withinthe scope ofthat authority because it addresses an unsafe conditionthat is likelyto exist or develop onproducts identified in this rulemaking action. Regulatory Findings We determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect onthe States, on the relationship betweenthe national government and the States, or onthe distribution of power and responsibilities among the various levels ofgovernment. Forthe reasons discussed above, I certify this AD: 4(1) Is not a "significantregulatory action" under Executive Order 12866, (2) Is not a "significant rule" underthe DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), (3) Will not affect intrastate aviation in Alaskato the extentthat itjustifies making a regulatory distinction, and (4) Will nothave a significant economic impact, positive or negative, on a substantial number ofsmall entities under the criteria ofthe Regulatory Flexibility Act. List ofSubjects in 14 CFRPart 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption ofthe Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFRpart 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.
