Airworthiness Directives; Eurocopter France Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for 
Eurocopter France (Eurocopter) Model AS332C, AS332L, AS332L1, AS332L2, 
and EC225LP helicopters. This AD requires visually inspecting each 
jettisonable emergency exit window panel (window) for sealant, and 
removing any sealant that exists in the window's extruded sections. 
This AD was prompted by jettison tests during routine maintenance 
inspections that showed the windows failed to jettison. The actions of 
this AD are intended to prevent failure of the windows to jettison, so 
helicopter occupants can exit the aircraft during an emergency.

DATES: This AD is effective January 24, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain documents listed in this AD as of January 24, 
2014.

SUPPLEMENTARY INFORMATION: 

Discussion

    On June 20, 2013, at 78 FR 37156, the Federal Register published 
our notice of proposed rulemaking (NPRM), which proposed to amend 14 
CFR part 39 by adding an AD that would apply to Eurocopter Model 
AS332C, AS332L, AS332L1, AS332L2 and EC225LP helicopters that have 
never undergone a window-jettison test. The NPRM proposed to require 
visually inspecting each window for sealant, and removing any sealant 
that exists in the window's extruded sections. The proposed 
requirements were intended to prevent failure of the windows to 
jettison, so helicopter occupants can exit the aircraft during an 
emergency.
    The NPRM was prompted by AD No. 2012-0152, dated August 13, 2012, 
issued by EASA, which is the Technical Agent for the Member States of 
the European Union. EASA issued AD No. 2012-0152 to correct an unsafe 
condition for certain Eurocopter Model AS 332 C, AS 332 C1, AS 332 L, 
AS 332 L1, AS 332 L2 and EC 225 LP helicopters. EASA reports that 
during required maintenance checks, there have been problems 
jettisoning emergency exit windows. According to EASA, investigations 
on several windows showed sealant between the extrusion and the window. 
``This condition, if not detected and corrected, could prevent the 
jettisoning of a window, possibly affecting the evacuation of 
passengers in the event of an emergency situation,'' EASA states.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we received no comments on the NPRM (78 FR 37156, June 20, 
2013).

[[Page 76985]]

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 issuing 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 and that air safety and the public interest require 
adopting the AD requirements as proposed.

Differences Between This AD and the EASA AD

    The EASA AD applies to Model AS 332 C1 helicopters, and this AD 
does not because that model is not FAA type-certificated. The EASA AD 
requires the inspection of each window within 110 hours time-in-service 
(TIS) or six months, while this AD requires the inspection within 110 
hours TIS.

Related Service Information

    Eurocopter issued Alert Service Bulletin (ASB) No. AS332-56.00.04 
for Model AS332C, AS332C1, AS332L, AS332L1, and AS332L2 helicopters and 
ASB No. EC225-56A002 for the EC225LP helicopter, both Revision 0, and 
both dated August 8, 2012. Eurocopter advises of difficulties 
jettisoning the window panel when performing a jettison test due to 
sealant installed between the extrusion and the window. According to 
Eurocopter, jettison tests are to be performed every two years. The 
ASBs provide instructions to inspect each jettisonable window panel to 
determine whether there is sealant between the extrusion and the 
window.

Costs of Compliance

    We estimate that this AD affects 19 helicopters of U.S. Registry 
and that labor rates average $85 a work-hour. Based on these estimates, 
we expect the following costs:
     Visually inspecting the windows for sealant requires 1 
work-hour for a labor cost of $85 per helicopter, and $1,615 for the 
U.S. fleet.
     If needed, removing the sealant from the windows requires 
2 work-hours for a labor cost of $170 per window.

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 helicopters identified in this 
rulemaking action.

Regulatory Findings

    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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under 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 AD and placed it in the AD docket.
