Federal Register Abstract
We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS 365 N3, EC 155B, and EC155B1 helicopters with certain external life rafts. This AD requires installing a sheath kit on the left-hand and right-hand raft deployment control systems. This AD is prompted by a report that the life raft deployment control could not be adjusted due to problems with the life raft deployment linkage. This unsafe condition, if not corrected, could result in failure of the external life raft to deploy and prevent evacuation of passengers during an emergency.

on the left-hand and right-hand raft deployment control systems. This
AD is prompted by a report that the life raft deployment control could
not be adjusted due to problems with the life raft deployment linkage.
This unsafe condition, if not corrected, could result in failure of the
external life raft to deploy and prevent evacuation of passengers
during an emergency.

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

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. 2015-0048, dated March 17, 2015,
to correct an unsafe condition for Airbus Helicopters Model AS 365 N3,
EC 155B, and EC155B1 helicopters. EASA advises that after installation
of a new life raft on a helicopter, the travel of the life raft
deployment control could not be properly adjusted, putting at risk
proper life raft inflation. According to a technical analysis, the
varying positions of the life raft inflation cylinder inside the bag
containing the life raft, as well as the varying positions of the bag
within the life raft container, may cause the life raft deployment
control cable to loosen and travel insufficiently.
This condition could result in failure of the external life raft to
deploy after a ditching, impeding or preventing the safe evacuation of
helicopter occupants, EASA states. EASA consequently requires
alteration of the life raft deployment control by installing a sheath
kit, which Airbus Helicopters identifies as Modification 365A084711.00
and 365A084711.01.
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
[[Page 12805]]
provided by EASA and determined the unsafe condition exists and is
likely to exist or develop on other helicopters of these same type
designs.
Related Service Information Under 1 CFR Part 51
We reviewed Airbus Helicopters Alert Service Bulletin (ASB) No.
AS365-25.01.45 and ASB No. EC155-25A128, both Revision 1, and both
dated February 2, 2015. The service information reports that the
position of the life raft inflation cylinder may slacken the deployment
control cable for new life rafts installed on Model AS 365 N3, EC 155B,
and EC155B1 helicopters. In one instance, travel of the life raft
deployment control could not be adjusted as stated in the maintenance
manual. This anomaly is due to the varying positions of the inflation
cylinder inside the bag that contains the life raft, and the varying
positions of the bag inside the container, related to the installation
and removal of optional equipment, calendar overhauls, life raft
storage, shock impacts, and in-flight vibrations. Airbus Helicopters
consequently developed modification 365A084711.00 and 365A084711.01,
which ensure sufficient travel of the life raft deployment control
cable in all positions of the inflation cylinder by installing an
improved sheath kit on the left hand and right hand deployment
controls.
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, before the next flight over water, installing a
sheath kit on the left-hand and right-hand raft deployment controls.
Differences Between This AD and the EASA AD
The EASA AD requires installing a sheath kit on the left-hand and
right-hand raft deployment controls within 110 hours time-in-service or
before further flight for helicopters required to have life rafts,
whichever occurs later. This AD requires installing a sheath kit on the
left-hand and right-hand raft deployment controls before the next
flight over water.
Costs of Compliance
We estimate that this proposed AD affects 23 helicopters of U.S.
Registry and that labor costs average $85 per work-hour. Based on these
estimates, we expect that installing the sheath kits requires 4 work-
hours and a parts cost of $50 for a total cost of $390 per helicopter
and $8,970 for the U.S. fleet.
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 find that
the risk to the flying public justifies waiving notice and comment
prior to the adoption of this rule because many of the affected
helicopters are located along major waterways, and the required
corrective actions must be accomplished before the next flight over
water.
Since an unsafe condition exists that requires the immediate
adoption of this AD, we determined that notice and opportunity for
prior public comment before issuing this AD are impracticable and
contrary to the public interest and that good cause exists to make this
AD 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.
