14 CFR Part 39

[Docket No. FAA-2016-4551; Directorate Identifier 2016-NE-07-AD; 
Amendment 39-18576; AD 2016-13-12]

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 
Rolls-Royce 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 (P/N) 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 August 5, 2016.

ADDRESSES: For service information identified in this final rule,

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 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 P/N BRR17117, was the failure cause.
    This condition, if not corrected, could lead to loss of the fuel 
shut-off 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, April 1, 
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) BR700-72-A101523, 
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.

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:
    (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.

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
