14 CFR Part 39 

[Docket No. FAA-2016-4551; Directorate Identifier 2016-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 carrier pivot pins, part number 

(PIN) BRR17117, from service and replacing them with parts eligible for installation. 

This AD was prompted by a seized low-pressure turbine (LPT) fuel shut-off pawl carrier 

caused by corrosion of the pawl carrier pivot pin. We are issuing this AD to prevent 

failure of the fuel shut-off mechanism, which could result in uncontained part release, 

damage to the engine, and damage to the airplane. 

DATES: This AD becomes effective [INSERT DATE 35 DAYS AFTER DATE OF 

PUBLICATION IN THE FEDERAL REGISTER]. 

ADDRESSES: For service information identified in this 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. You may view this

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 

2 
the Federal Register on April 1, 2016 (81 FR 18806). The NPRM proposed to correct an 

unsafe condition for the specified products. The MCAI states: 

Seizing of a fuel shut -off mechanism pawl carrier was reported. 

The subsequent investigation determined that corrosion of the pawl 

carrier pivot pin PIN BRR17117, was the failure cause. 

This condition, if not corrected, could lead to loss of the fuel shutoff mechanism functionality and loss of the engine over-speed 

protection, possibly resulting in release of high-energy debris, with 

consequent damage to, and/or reduced control of the 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 Docket No. 

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-A1 01523, Revision 3, 

dated December 10, 2015. The service information describes procedures for replacing the 

pawl carrier pivot pins. This service information is reasonably available because the 

interested parties have access to it through their normal course of business or by the 

means identified in the ADDRESSES section. 

3 
Costs of Compliance 

We estimate that this AD affects 4 engines installed on airplanes of U.S. registry. 

We also estimate that it will take about 3 hours per engine to comply with this AD. The 

average labor rate is $85 per hour. Required parts cost about $860 per engine. Based on 

these figures, we estimate the cost of this AD on U.S. operators to be $4,460. 

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 AD will not have federalism implications under 

Executive Order 13132. This AD will 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 AD: 

4 
(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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 

Adoption of the Amendment 

Accordingly, under the authority delegated to me by the Administrator, the FAA 

amends 14 CFR part 39 as follows:
