RIN 2120-AA64

Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG 
Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

[[Page 18807]]

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt 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 proposed AD was prompted 
by a seized low-pressure turbine (LPT) fuel shut-off pawl carrier 
caused by corrosion of the pawl carrier pivot pin. This proposed AD 
would require removing the pawl carrier pivot pins, part number (P/N) 
BRR17117, from service and replacing them with parts eligible for 
installation. We are proposing this AD to prevent failure of the fuel 
shut-off mechanism, uncontained part release, damage to the engine, and 
damage to the airplane.

DATES: We must receive comments on this proposed AD by May 31, 2016.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.
     Mail: Docket Management Facility, U.S. Department of 
Transportation, 1200 New Jersey Avenue SE., West Building Ground Floor, 
Room W12-140, Washington, DC 20590-0001.
     Hand Delivery: Deliver to Mail address above between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2016-0034, dated February 24, 2016 (referred to hereinafter as ``the 
MCAI''), 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.

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 NPRM would require removing the pawl carrier 
pivot pin, P/N BRR17117, from service and replacing with a part 
eligible for installation.

Related Service Information

    RRD has issued ASB SB-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 proposed AD affects 4 engines installed on 
airplanes of U.S. registry. We also estimate that it would take about 3 
hours per engine to comply with this proposed 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 proposed 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 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),

[[Page 18808]]

    (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.
