Federal Register Volume 83, Issue 78 (April 23, 2018)

We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model EC225LP helicopters. This AD requires inspecting each main rotor rotating swashplate (swashplate) control rod attachment yoke (yoke). This AD is prompted by a finding that the yoke is susceptible to cracking. The actions of this AD are intended to address an unsafe condition on these products.

SUPPLEMENTARY INFORMATION: 

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments prior to it becoming effective. However, we 
invite you to participate in this rulemaking by submitting written 
comments, data, or views. We also invite comments relating to the 
economic, environmental, energy, or federalism impacts that resulted 
from adopting this AD. The most helpful comments reference a specific 
portion of the AD, explain the reason for any recommended change, and 
include supporting data. To ensure the docket does not contain 
duplicate comments, commenters should send only one copy of written 
comments, or if comments are filed electronically, commenters should 
submit them only one time. We will file in the docket all comments that 
we receive, as well as a report summarizing each substantive public 
contact with FAA personnel concerning this rulemaking during the 
comment period. We will consider all the comments we receive and may 
conduct additional rulemaking based on those comments.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2017-0191R2, dated December 15, 
2017, to correct an unsafe condition for Airbus Helicopters Model EC 
225 LP helicopters with swashplate part number (P/N) 332A31-3074-00 or 
P/N 332A31-3074-01 installed. EASA advises of a finding by Airbus 
Helicopters that the yoke is susceptible to cracking due to strain 
aging of the metal. EASA advises that this condition, if not detected 
and corrected, could lead to structural failure of a yoke, possibly 
resulting in loss of control of the helicopter.
    Accordingly, the EASA AD requires, for swashplates that are seven 
or more years old, a recurring inspection of the five yokes for a crack 
and a one-time inspection of the yokes for corrosion and a crack. If 
there is a crack or corrosion on a yoke, the EASA AD requires replacing 
the swashplate or repairing and reworking the yokes.

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 the same type 
design.

Related Service Information Under 1 CFR Part 51

    Airbus Helicopters has issued one document that co-publishes two 
Emergency Alert Service Bulletin (EASB) identification numbers: No. 
05A051 for Model EC225LP helicopters and No. 05A046 for non-FAA type-
certificated Model EC725AP helicopters, both Revision 1 and both dated 
November 16, 2017. Airbus Helicopters EASB No. 05A051 is incorporated 
by reference in this AD. Airbus Helicopters EASB No. 05A046 is not 
incorporated by reference in this AD.
    This service information specifies inspections for certain serial-
numbered swashplate P/N 332A31-3074-00 and P/N 332A31-3074-01. This 
service information specifies a repetitive inspection of the yokes for 
a crack and a one-time inspection of the stripped yokes for corrosion 
and a crack. If in doubt about whether there is a crack, this service 
information specifies performing a non-destructive inspection. This 
service information also specifies touching up the swashplate if there 
is corrosion, removing any damage within allowable limits, and 
refinishing the yokes. If there is a crack in a yoke, this service 
information specifies replacing the swashplate.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

AD Requirements

    This AD requires a repetitive visual inspection of the five yokes 
for a crack every 15 hours time-in-service (TIS), and replacing the 
swashplate if there is a crack in any of the yokes.

Differences Between This AD and the EASA AD

    The EASA AD specifies performing a non-destructive inspection if in 
doubt about if there is a crack and removing damage within allowable 
limits, whereas this AD does not. The EASA AD also specifies stripping 
the yokes and performing a one-time inspection within 100 hours TIS for 
corrosion and a crack, and this AD does not. We plan to publish a 
notice of proposed rulemaking to give the public an opportunity to 
comment on this long-term requirement.

Costs of Compliance

    We estimate that this AD affects 5 helicopters of U.S. Registry. We 
estimate that operators may incur the following costs in order to 
comply with this AD. Labor costs are estimated at $85 per work-hour.
    Inspecting the yokes takes about 0.25 work-hour for an estimated 
cost of $21 per helicopter and $105 for the U.S. fleet per inspection 
cycle. Replacing a swashplate takes about 6 work-hours and parts cost 
about $82,000 for an estimated cost of $82,510 per helicopter.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies waiving notice and comment prior to adoption of this rule 
because the required corrective action must be completed within 15 
hours TIS. Therefore, we find good cause that notice and opportunity 
for prior public comment are impracticable. In addition, for the reason 
stated above, we find that good cause exists for making this amendment 
effective in less than 30 days.

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 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, 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.
