Federal Register Abstract
We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model MBB-BK 117 C-2 helicopters with a certain Goodrich rescue hoist damper unit (damper unit) installed. This AD requires repairing or replacing the damper unit or deactivating the rescue hoist. This AD is prompted by a report of an uncommanded detachment of a damper unit from the cable. These actions are intended to prevent loss of an external load or person from the helicopter hoist and injury to persons being lifted by the hoist.

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 AD No. 2014-0057, dated March 6, 2014, and
corrected March 7, 2014 (AD 2014-0057), to correct an unsafe condition
for Airbus Helicopters Model MBB-BK 117 C-2 helicopters. EASA advises
that a rescue hoist damper unit detached from the cable when the hoist
damper was lifted by hand with no load attached. EASA further advises
that an investigation revealed the retaining ring inside the damper
unit was not located in the proper position, and that this displacement
of the retaining ring may have occurred as a maintenance error or as a
result of interference with the bonding strap unit during normal use.
EASA further states that this condition could lead to the detachment of
an external load or person from the helicopter hoist, possibly
resulting in personal injury or injury to persons on the ground.
To address this unsafe condition, EASA issued AD 2014-0057, which
supersedes AD No. 2014-0046-E, dated February 27, 2014, and which
requires replacing Goodrich rescue hoist damper unit/rescue winch
damper, part number (P/N) 44307-480, P/N 44307-480-1, or P/N 44307-480-
2, or deactivating the rescue hoist. AD 2014-0057 also requires
modifying the damper unit's bonding strap and replacing the retaining
ring, which allows reactivation of the rescue hoist. Lastly, AD 2014-
0057 implements a recurring 100 hoist-cycle inspection of the retaining
ring for correct installation.
FAA's Determination
These helicopters have been approved by the aviation authority of
Germany and are approved for operation in the United States. Pursuant
to our bilateral agreement with Germany, 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
Airbus Helicopters has issued Emergency Alert Service Bulletin No.
ASB MBB-BK117 C-2-85A-041, Revision 2, dated March 4, 2014, which
describes procedures for modifying the bonding strap unit, installing
an improved retaining ring, and inspecting the retaining ring.
AD Requirements
This AD requires, before the next hoist operation, either repairing
the hoist damper unit by following specified portions of the service
information, replacing the hoist damper unit with a unit that has been
repaired by following specified portions of the service information, or
deactivating the rescue hoist.
Differences Between This AD and the EASA AD
The EASA AD requires a 100 hoist-cycle repetitive inspection, while
this AD does not. We plan to publish a notice of proposed rulemaking to
give the public an opportunity to comment on those long-term
requirements.
Interim Action
We consider this AD to be an interim action. If final action is
later identified, we might consider further rulemaking then.
[[Page 36637]]
Costs of Compliance
We estimate that this AD will affect 118 helicopters of U.S.
Registry. We estimate that operators may incur the following costs in
order to comply with this AD. At an average labor rate of $85 per hour,
repairing the hoist damper unit will require 5 work-hours, and required
parts will cost $4, for a cost per helicopter of $429. Replacing the
hoist damper unit will require 1 work-hour, and required parts will
cost $8,715, for a cost per helicopter of $8,800. Deactivating the
rescue hoist will require .5 work-hour, for a cost per helicopter of
$43.
According to Airbus Helicopters' service information, some of the
costs of this AD may be covered under warranty, thereby reducing the
cost impact on affected individuals. We do not control warranty
coverage by Airbus Helicopters. Accordingly, we have included all costs
in our cost estimate.
FAA's Justification and Determination of the Effective Date
Providing an opportunity for public comments before 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
adopting this rule because the required corrective actions must be done
before the next hoist operation.
Since an unsafe condition exists that requires the immediate
adoption of this AD, we determined that notice and opportunity for
public comment before issuing this AD are impracticable and contrary to
the public interest and 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.
