[Docket No. FAA-2013-0984; Directorate Identifier 2013-SW-022-AD]
RIN 2120-AA64

Airworthiness Directives; Eurocopter France Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
Eurocopter (Eurocopter) France Model EC225LP helicopters. This proposed 
AD would require measuring the operating load of the cockpit fuel shut-
off controls and replacing the tangential gearbox if the operating load 
threshold is exceeded. This proposed AD is prompted by the jamming of 
the left-hand (LH) side of the fuel shut-off and general cut-off 
controls (controls). The proposed actions are intended to prevent the 
jamming of the controls so that a pilot can shut down an engine during 
an engine fire or during an emergency landing.

DATES: We must receive comments on this proposed AD by January 24, 
2014.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Docket: Go to http://www.regulations.gov. Follow the online instructions for sending your 
comments electronically.
     Fax: 202-493-2251.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2013-0098-E, dated April 24, 
2013, to correct an unsafe condition for Eurocopter Model EC225LP 
helicopters with tangential gearboxes, part number (P/N) 200181 or 
Eurocopter P/N 704A34112012. EASA advises that during maintenance on a 
helicopter, the LH side of the cockpit's emergency shutdown controls 
were reported jammed, making it impossible to operate the LH fuel shut-
off and the general cut-out handles. ``This condition, if not detected 
and corrected, could lead to failure to manually operate the helicopter 
emergency shutdown controls during emergency landing or fire 
condition,'' EASA states. To address this unsafe condition, EASA AD No. 
2013-0098-E requires an operating load check of the two cockpit fuel 
shut-off handles and, depending on findings, lubrication and/or 
replacement of the two tangential gearboxes.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
France and are approved for operation in the United States. Pursuant to 
our bilateral agreement with France, EASA, its technical 
representative, has notified us of the unsafe condition described in 
the EASA AD. 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 helicopters of these same 
type designs.

Related Service Information

    Eurocopter issued Emergency Alert Service Bulletin (ASB) No. 
76A001, Revision 0, dated April 22, 2013, for the Model EC225LP civil 
helicopter and the Model EC725 military helicopter to notify its 
operators that during a scheduled inspection of the fuel shut-off 
controls, a mechanic noticed that one of the shut-off controls jammed. 
This jamming made maneuvering the fuel shut-off and the general cut-out 
controls impossible. After an investigation, Eurocopter determined that 
the jamming originated in the tangential gearbox installed on this 
control. Traces of corrosion were observed on the internal bearings of 
the LH tangential gearbox, Eurocopter reported. The jamming of the fuel 
cut-off control prevents the engine input fuel valve and the engine 
compartment ventilation flap from closing and prevents the activation 
of the general cut-out control.
    Eurocopter consequently called for a mandatory ``check'' of the 
fuel shut-off valve maneuvering loads, lubricating the tangential 
gearbox bearings, and depending on the load measurement, replacing the 
tangential gearbox.

Proposed AD Requirements

    This proposed AD would require:
     Within 15 hours time-in-service (TIS) or 7 days, whichever 
occurs first, measuring the operating load of each cockpit fuel shut-
off control.
     If the operating load is more than 3 daN (6.74 ft-lb), 
before further flight, lubricating each tangential gearbox and 
measuring the operating load of each cockpit fuel shut-off control.
     If the operating load is less than or equal to 3 daN (6.74 
ft-lb), within 6 months, lubricating the tangential gearbox.
     If the operating load is more than 3 daN (6.74 ft-lb) 
after lubricating the tangential gearbox, replacing the affected 
tangential gearbox before the next flight.

Differences Between This Proposed AD and the EASA AD

    The EASA AD requires differing compliance times based on when the 
helicopter's original Certificate of Airworthiness or Export 
Certificate of Airworthiness was issued. This proposed AD makes no 
distinction regarding compliance times because there are only 4 
affected aircraft on the U.S. registry.

Costs of Compliance

    We estimate that this proposed AD would affect 4 helicopters of 
U.S. Registry and that labor costs would average $85 a work-hour. Based 
on these estimates, we expect the following costs:
     Measuring the operating load of the two cockpit fuel shut-
off controls would require .25 work-hours for a labor cost of about 
$21, or $84 for the U.S. fleet. No parts would be needed.
     Lubricating the tangential gearbox would require 4 work-
hours. The cost of consumable materials would be minimal for a total 
cost of $340 per helicopter.
     Replacing the tangential gearbox would require 4 work-
hours for a labor cost of $340. Parts would cost $4,943 for a total 
cost of $5,283 per helicopter.

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, 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 an economic evaluation of the estimated costs to comply 
with this proposed AD and placed it in the AD docket.
