Airworthiness Directives; Airbus Helicopters (Formerly Eurocopter 
France)

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

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

SUMMARY: We are publishing a new airworthiness directive (AD) for 
Airbus Helicopters (formerly Eurocopter France) Model EC130T2 
helicopters, which was sent previously to all known U.S. owners and 
operators of these helicopters. This AD requires repetitively 
inspecting the attachment points where the fan attaches to the main 
gearbox (MGB) oil cooler hopper (hopper) and replacing any cracked 
hopper with an airworthy hopper. This AD is prompted by several cases 
of a cracked hopper. The cracks were found on the hopper at the fan 
attachment points. These actions are intended to detect a crack in the 
hopper at a fan attachment point to prevent failure of the fan 
attachment, interference of the fan with the control rod of the front 
servo-control or with the flight control bellcrank, and subsequent loss 
of control of the helicopter.

DATES: This AD becomes effective February 25, 2015 to all persons 
except those persons to whom it was made immediately effective by 
Emergency AD (EAD) 2014-22-51, issued on October 29, 2014, which 
contained the requirements of this AD.
    The Director of the Federal Register approved the incorporation by 
reference of a certain document listed in this AD as of February 25, 
2015.
    We must receive comments on this AD by April 13, 2015.

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

    On October 29, 2014, we issued EAD 2014-22-51, which requires, 
before further flight and thereafter at intervals not to exceed 10 
hours time-in-service (TIS), visually inspecting the hopper for a crack 
at the four attachment points. If there is a crack, EAD 2014-22-51 
requires replacing the hopper with an airworthy hopper, which is not 
terminating action for the repetitive visual inspections. EAD 2014-22-
51 was sent previously to all known U.S. owners and operators of these 
helicopters and resulted from several cases of a cracked MGB oil cooler 
hopper.
    EAD 2014-22-51 was prompted by EAD No. 2014-0229-E, dated October 
20, 2014, issued by EASA, which is the Technical Agent for the Member 
States of the European Union, to correct an unsafe condition for the 
Airbus Helicopters Model EC130T2 helicopters. EASA advises of several 
cases of cracked MGB oil cooler fan attachments to the hopper. EASA EAD 
No. 2014-0229-E requires repetitive visual inspections of the MGB oil 
cooler fan attachment to the hopper and, depending on findings, 
replacement of cracked parts.

FAA's Determination

    This helicopter has been approved by the aviation authority of 
France and is

[[Page 7289]]

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 EAD. 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 issued Emergency Alert Service Bulletin No. 
05A020 Revision 0, dated October 20, 2014 (EASB), specifying periodic 
visual checks for cracks in the engine MGB oil fan hopper. The EASB 
states that a crack could lead to the total failure of the fan 
attachment and that this condition, if not detected and corrected, 
could lead to interference of the fan with the control rod of the front 
servo-control or with the flight control bellcrank, possibly resulting 
in reduced control of the helicopter. Also, the EASB states that 
pending modification, the periodic visual check of the hopper is 
necessary. This service information is reasonably available; see 
ADDRESSES for ways to access this service information.

AD Requirements

    This AD requires, before further flight and thereafter at intervals 
not to exceed 10 hours TIS, visually inspecting the hopper for a crack 
at the four fan attachment points. If there is a crack in the hopper, 
this AD requires replacing the hopper with an airworthy hopper. 
Replacing the hopper does not constitute terminating action for the 
repetitive visual inspections required by this AD.

Differences Between This AD and the EASA AD

    We do not use the compliance time option of every 7 days.

Interim Action

    We consider this AD to be an interim action. The design approval 
holder is currently developing a modification that will address the 
unsafe condition identified in this AD. Once this modification is 
developed, approved, and available, we might consider additional 
rulemaking.

Costs of Compliance

    We estimate that this AD will affect 60 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 hour. We 
estimate 0.2 work hour to inspect the hopper at an estimated $17 per 
helicopter and a total cost of $1,020 for the fleet. If a hopper is 
replaced, we estimate 6 hours to replace it and $1,000 for required 
parts for a total of $1,510.

FAA's Justification and Determination of the Effective Date

    Providing an opportunity for public comments prior to adopting 
these AD requirements would delay implementing the safety actions 
needed to correct this known unsafe condition. Therefore, we found and 
continue to find that the risk to the flying public justifies waiving 
notice and comment prior to the adoption of this rule because the 
previously described unsafe condition can adversely affect the 
controllability of the helicopter and the required corrective actions 
must be accomplished before further flight and in 10-hour intervals.
    Since it was found that immediate corrective action was required, 
notice and opportunity for prior public comment before issuing this AD 
were impracticable and contrary to the public interest and good cause 
existed to make the AD effective immediately by EAD 2014-22-51, issued 
on October 9, 2014, to all known U.S. owners and operators of these 
helicopters. These conditions still exist and the AD is hereby 
published in the Federal Register as an amendment to section 39.13 of 
the Federal Aviation Regulations (14 CFR 39.13) to make it effective to 
all persons.

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.
