Federal Register Abstract
We are superseding Airworthiness Directive (AD) 2010- 21-01 for Eurocopter France (Eurocopter) Model AS350B, BA, B1, B2, B3, D, AS355E, F, F1, F2, and N helicopters. AD 2010-21-01 required an inspection to determine whether a cross-member is installed at station X 2165 and doublers at X 2325 and Y 269, and installing them if they are missing. This new AD retains the requirements of AD 2010-21-01 but clarifies the inspection procedures and limits the applicability to only those helicopters with collective-to-yaw control coupling. This AD is prompted by a crack discovered in the area of the center cross-member at station X 2325, at the attachment point of the yaw channel ball-type control sheath stop, of a Model AS355N helicopter fitted with the collective-to-yaw control coupling. The actions of this AD are intended to prevent reduced yaw control and subsequent loss of helicopter control.

helicopters. AD 2010-21-01 required an inspection to determine whether
a cross-member is installed at station X 2165 and doublers at X 2325
and Y 269, and installing them if they are missing. This new AD retains
the requirements of AD 2010-21-01 but clarifies the inspection
procedures and limits the applicability to only those helicopters with
collective-to-yaw control coupling. This AD is prompted by a crack
discovered in the area of the center cross-member at station X 2325, at
the attachment point of the yaw channel ball-type control sheath stop,
of a Model AS355N helicopter fitted with the collective-to-yaw control
coupling. The actions of this AD are intended to prevent reduced yaw
control and subsequent loss of helicopter control.
DATES: This AD is effective December 30, 2013.
The Director of the Federal Register approved the incorporation by
reference of certain documents listed in this AD as of December 30,
2013.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2010-21-01, Amendment 39-16461 (75 FR 63050,
October 14, 2010), which applied to Eurocopter Model AS350B, BA, B1,
B2, B3, D, AS355E, F, F1, F2, and N helicopters. The NPRM was published
in the Federal Register on July 3, 2013 (78 FR 40045). AD No. 2010-21-
01 required within 10 hours time-in-service (TIS) or 1 month,
inspecting the helicopters to determine whether a cross-member is
installed at station X 2165 and doublers at X 2325 and Y 269. If the
cross-member and doublers are not installed, AD No. 2010-21-01 required
inspecting for a crack in the center cross-member, and replacing the
center cross-member if there is a crack before further flight. If a
crack does not exist, AD No. 2010-21-01 required inspecting the tail
rotor control rigging before further flight. Lastly, if needed, AD
2010-21-01 required installing a cross-member and two doublers within
55 hours TIS. AD 2010-21-01 was prompted by AD No. 2007-0139-E, dated
May 15, 2007 (corrected May 23, 2007), issued by EASA, which is the
Technical Agent for the Member States of the European Union. EASA
advised that a crack was discovered in the area of the center cross-
member at station X 2325, at the attachment point of the yaw channel
ball-type control sheath stop, of a Model AS355N helicopter fitted with
the collective-to-yaw control coupling.
Since we issued AD No. 2010-21-01, we discovered that we included
all helicopters in the AD applicability rather than limiting it to only
those helicopters with collective-to-yaw control coupling. Therefore,
this new AD retains the requirements in AD No. 2010-21-01 with some
revisions for the inspection of the tail rotor control rigging to
clarify those procedures. This AD also reduces the applicability to
only those Model AS350 and AS355 helicopters with collective-to-yaw
control coupling installed.
Comments
We gave the public the opportunity to participate in developing
this AD, but we received no comments on the NPRM (78 FR 40045, July 3,
2013).
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
This AD differs from the EASA AD as follows:
<bullet> We require the installation of the cross-member at station
X 2165 and the two doublers at stations X 2325 and Y 269 within 55
hours time-in-service. The EASA AD requires that this action be
accomplished within 12 months.
<bullet> We do not require repetitive inspections if no crack
exists in the center cross-member, whereas the EASA AD does.
<bullet> We do not include military model helicopters in the
applicability.
Related Service Information
We reviewed Eurocopter Emergency Alert Service Bulletin (EASB),
Revision 0, dated April 11, 2007, that contains three different numbers
(Nos. 53.00.37, 53.00.11, and 53.00.23) for Eurocopter Model 350, 355,
550, and 555 helicopters. EASB No. 53.00.37 relates to two Model 350
(350 BB and 350 L1) helicopters that are not type certificated in the
United States. EASB No. 53.00.11 relates to four Model 550 and six
Model 555 military helicopters that are not type-certificated in the
United States. The EASB describes procedures for checking the
conformity for the cross member at X 2325 under the cabin floor. The
actions in the EASA AD are intended to correct the same unsafe
condition as that identified in the service bulletin.
Costs of Compliance
We estimate that this AD affects 72 helicopters of U.S. Registry
and that labor costs average $85 a work-hour. It takes about one work-
hour to perform the inspections, and if needed, to install the cross-
member, two doublers and an airworthy center-cross member. Required
parts cost about $161 per helicopter. Based on these figures, we
estimate the cost of the AD to be $246 per helicopter and $17,712 for
the fleet if all repairs are needed.
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:
[[Page 70204]]
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.
