[Docket No. FAA-2013-0882; Directorate Identifier 2013-NE-29-AD]
RIN 2120-AA64


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

AGENCY: Federal Aviation Administration (FAA), DOT.

[[Page 8906]]


ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Rolls-Royce Deutschland Ltd & Co KG (RRD) BR700-725A1-12 turbofan 
engines. This proposed AD was prompted by reports of wear on the 
receptors of the double-ended unions in the fuel metering unit (FMU) 
housing on BR700-725A1-12 engines causing fuel leakage. This proposed 
AD would require removal of the affected FMUs. We are proposing this AD 
to prevent failure of the FMU, which could lead to damage to one or 
more engines and damage to the airplane.

DATES: We must receive comments on this proposed AD by April 15, 2014.

ADDRESSES: You may send comments by any of the following methods:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2013-0229R1, dated November 21, 2013 (referred to hereinafter as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Occurrences have been reported of finding wear on the receptors 
of the double-ended unions in the Fuel Metering Unit (FMU) housing 
on BR700-725A1-12 engines.
    This condition, if not corrected, could lead to fuel leak 
resulting in engine in-flight shutdown and consequent reduced 
control of the aeroplane.

    Failure of the FMU due to these conditions will result in loss of 
thrust control and damage to the engine. You may examine the MCAI in 
the AD docket on the Internet at http://www.regulations.gov by 
searching for and locating it in Docket No. FAA-2013-0882.

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 proposed AD would require removal of the 
affected FMUs and their replacement with a part eligible for 
installation.

Costs of Compliance

    We estimate that this proposed AD affects 24 RRD turbofan engines 
installed on aircraft of U.S. registry. We also estimate that it would 
take about 6 hours per engine to comply with this proposed AD. The 
average labor rate is $85 per hour. Required parts cost about $293,960 
per engine. Based on these figures, we estimate the cost of this 
proposed AD on U.S. operators to be $7,067,280.

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 proposed 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

[[Page 8907]]

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),
    (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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

(c) Applicability

    This AD applies to all Rolls-Royce Deutschland Ltd & Co KG (RRD) 
BR700-725A1-12 turbofan engines.

(d) Reason

    This AD was prompted by reports of wear on the receptors of the 
double-ended unions in the fuel metering unit (FMU) housing on 
BR700-725A1-12 engines causing fuel leakage. We are issuing this AD 
to prevent failure of the FMU, which could lead to damage to one or 
more engines, and damage to the airplane.

(e) Actions and Compliance

    Comply with this AD within the compliance times specified, 
unless already done.
    (1) After the effective date of this AD, before the FMU has 
accumulated 650 flight hours (FHs) since new, or within 30 days, 
whichever occurs later, remove FMU part number (P/N) G3000FMU02 or 
P/N G3000FMU03, and replace it with a part eligible for 
installation.
    (2) Thereafter, remove the FMU at intervals not to exceed 650 
FHs and replace it with a part eligible for installation.

(f) Installation Prohibition

    After the effective date of this AD, do not install FMU P/N 
G3000FMU02 onto any engine, or install any engine with FMU P/N 
G3000FMU02 onto any airplane.

(g) Definition

    For the purpose of this AD, an FMU eligible for installation is 
a new FMU or an FMU with P/N G3000FMU03 that has accumulated fewer 
than 650 FHs since installation on any airplane or since last repair 
using RRD Alert Non-Modification Service Bulletin (NMSB) No. ALERT 
SB-BR700-73-A900309, Revision 1, dated November 8, 2013.
