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 France (Eurocopter) Model AS332C, AS332L, AS332L1, AS332L2, 
and SA330J helicopters. This proposed AD would prohibit use of the 
hydraulic hoist in helicopters equipped with certain parts and 
configurations until a hoist beam lower fitting protector is installed. 
This proposed AD is prompted by a report that the hoist cable jammed 
during a rescue at sea. The proposed actions are intended to prevent 
the hoist cable from jamming and subsequent cable failure, which could 
result in injury and damage to the helicopter.

DATES: We must receive comments on this proposed AD by November 25, 
2013.

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

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
No. 2009-0271R1, dated July 8, 2011, to correct an unsafe condition for 
Eurocopter Model AS332C, AS332C1, AS332L1, AS332L2, and SA330J 
helicopters with certain hoist beams installed. EASA advises that 
during a hoisting operation, a hydraulic hoist cable jammed against the 
base of the supporting strut of a dual hoist tray installation. 
According to EASA, the load was transferred to the back-up electrical 
hoist and safely brought on board. However, the jamming of the 
hydraulic hoist cable against the strut damaged the back-up electrical 
hoist power supply harness, which is routed through the area, resulting 
in a short circuit that fused and ruptured the cable. EASA reports that 
this condition, if not corrected, could lead to further incidents of 
hoist cable jamming and subsequent cable failure, which could result in 
personal injuries and damage to the helicopter.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
France and

[[Page 59307]]

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 its AD. We are 
proposing this AD because we evaluated all known relevant information 
and determined that an unsafe condition is likely to exist or develop 
on other products of the same type design.

Related Service Information

    Eurocopter has issued one Emergency Alert Service Bulletin (EASB), 
Revision 3, dated July 6, 2011, with three different numbers. EASB No. 
25.02.08 is for civil and military Model AS332-series helicopters; EASB 
No. 25.01.29 is for military Model AS532-series helicopters; and EASB 
No. 25.39 is for civil and military Model SA330-series helicopters. The 
EASB originally provided instructions to prevent the main hydraulic 
hoist cable from becoming jammed and damaged in the fixed fitting of 
the hoist beam lower fitting. The revisions add further instructions 
and expand the effectivity to more helicopters and helicopter equipment 
configurations. The revisions also extend some compliance deadlines, 
and revise some instructions to account for improved installation 
procedures. After further investigation, the most recent revisions 
remove some helicopter models from the list of applicable helicopters.

Proposed AD Requirements

    This proposed AD would require installing a placard that prohibits 
raising or lowering the load in case of a cable jam. If the hoist 
control electrical harness is routed at the base of the hoist 
supporting strut, the proposed AD would require disabling the hoist 
pyrotechnic shear function and installing placards that state the hoist 
pyrotechnic shear function is disabled. The proposed AD would also 
require either installing a hoist beam lower fitting protector or 
installing placards that prohibit operating the hydraulic hoist.

Differences Between This Proposed AD and the EASA AD

    Our AD would differ from the EASA AD as follows:
    The EASA AD requires certain actions before the next flight, while 
we would require the same actions before the next hoisting operation.
    The EASA AD sets calendar dates that have passed for compliance, 
while we set compliance based on hours time-in-service.
    The EASA AD misidentifies the Eurocopter SA330J service bulletin 
number and paragraph number in its required actions for Model SA330J 
helicopters. This proposed AD would require compliance with paragraph 
2.B.4 of Eurocopter Emergency Alert Service Bulletin No. 25.39, 
Revision 3, dated July 5, 2011.

Costs of Compliance

    We estimate that this proposed AD would affect 20 helicopters of 
U.S. Registry and that work hours would average $85 an hour. Based on 
these estimates, we would expect the following costs:
     The cost for installing and removing placards is minimal.
     Disabling the hoist pyrotechnic shear function would 
require 1 work-hour and no parts would be needed for a cost of $85 per 
helicopter, $1,700 for the U.S. fleet.
     Installation of the hoist beam lower fitting protector for 
Model AS332 helicopters without a right hand (RH) sliding door and 
without a short footstep would require 6 work-hours for a labor cost of 
$510 per helicopter. Parts would cost $4,760 for a total cost of $5,270 
per helicopter.
     Installation of the hoist beam lower fitting protector and 
short footstep with lower side protector for Model AS332 helicopters 
without a RH sliding door and with a short footstep would require 12 
work-hours for a labor cost of $1020 per helicopter. Parts would cost 
$26,891 for a total cost of $27,401 per helicopter.
     Installation of the hoist beam protector for Model AS332 
helicopters with a RH sliding door would require 3 work-hours for a 
labor cost of $255 per helicopter. Parts would cost $20,858 for a total 
cost of $21,113 per helicopter.
     Installation of the hoist beam protector for Model SA330J 
helicopters would require 3 work-hours for a labor cost of $255 per 
helicopter. Parts would cost $4,774 for a total cost of $5,029 per 
helicopter.
    Enabling the hoist pyrotechnic shear function would require 1 work-
hour and no parts would be needed for a cost of $85 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.
