Airworthiness Directives; Eurocopter France Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: 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.

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:
     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.
     We do not require repetitive inspections if no crack 
exists in the center cross-member, whereas the EASA AD does.
     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.
