Federal Register Abstract
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.

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:
<bullet> 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.
<bullet> 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.

Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
2013-24-19 Eurocopter France Helicopters: Amendment 39-17696; Docket
No. FAA-2013-0524; Directorate Identifier 2012-SW-084-AD.
(a) Applicability
This AD applies to Eurocopter France (Eurocopter) Model AS332C,
AS332L, AS332L1, AS332L2 and EC225LP helicopters, certificated in
any category, that have never undergone a window-jettison test.
(b) Unsafe Condition
This AD defines the unsafe condition as the presence of sealant
on an emergency exit window panel. This condition could result in
the window failing to jettison, preventing the helicopter occupants
from exiting the aircraft during an emergency.
(c) Effective Date
This AD becomes effective January 24, 2014.
(d) Compliance
You are responsible for performing each action required by this
AD within the specified compliance time unless it has already been
accomplished prior to that time.
(e) Required Actions
Within 110 hours time-in-service (TIS), visually inspect each
jettisonable emergency exit window panel (window) by doing the
following:
(1) Lift the extrusion slightly using a flat tool that does not
cause scoring.
(2) Inspect for sealant on the inside and outside of the window
between the window and the extrusion and between the extrusion and
the structure.
Note 1 to paragraph (e)(2) of this AD: The presence of a
sealant bead on the extrusion parting lines, on the window pull-out
seal parting lines, and on the pull-out straps is expected, as shown
in Figure 1 of Eurocopter Alert Service Bulletin (ASB) No. AS332-
56.00.04 or ASB No. EC225-56A002, both Revision 0, and both dated
August 8, 2012, as applicable to your model helicopter.
(3) If there is no sealant as shown in Photo 1 of Figure 2 of
Eurocopter ASB No. AS332-56.00.04 or ASB No. EC225-56A002, as
applicable to your model helicopter, no further action is required.
(4) If there is sealant between the structure and the profile as
shown in Photo 2 of Figure 2 of Eurocopter ASB No. AS332-56.00.04 or
ASB No. EC225-56A002, as applicable to your model helicopter, or if
you cannot determine whether there is sealant, remove the extrusion.
(5) Remove all sealant from the extrusion, the window, and the
structure.
(6) If there is any crazing, cracking or other damage on the
extrusion, replace with an airworthy extrusion.
(f) Alternative Methods of Compliance (AMOCs)
(1) The Manager, Safety Management Group, FAA, may approve AMOCs
