We are superseding airworthiness directive (AD) 2014-13-01 for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 C-2 helicopters with a certain Goodrich rescue hoist damper unit (damper unit) installed. AD 2014-13-01 required repairing or replacing the damper unit or deactivating the rescue hoist. AD 2014-13-01 was prompted by a report of an uncommanded detachment of a damper unit from the cable. This new AD retains the optional requirement of deactivating the rescue hoist, expands the applicability, and requires either replacing or modifying the damper unit with a newly developed single- piece retainer. These actions are intended to prevent the hoist damper unit detaching from the cable resulting in loss of an external load or person from the helicopter hoist and injury to persons being lifted by the hoist.

ACTION: Final rule; request for comments.

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

SUMMARY: We are superseding airworthiness directive (AD) 2014-13-01 for 
Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 
117 C-2 helicopters with a certain Goodrich rescue hoist damper unit 
(damper unit) installed. AD 2014-13-01 required repairing or replacing 
the damper unit or deactivating the rescue hoist. AD 2014-13-01 was 
prompted by a report of an uncommanded detachment of a damper unit from 
the cable. This new AD retains the optional requirement of deactivating 
the rescue hoist, expands the applicability, and requires either 
replacing or modifying the damper unit with a newly developed single-
piece retainer. These actions are intended to prevent the hoist damper 
unit detaching from the cable resulting in loss of an external load or 
person from the helicopter hoist and injury to persons being lifted by 
the hoist.

Discussion

    On June 13, 2014, we issued AD 2014-13-01, Amendment 39-17875 (79 
FR 36635, June 30, 2014), to correct an unsafe condition for Airbus 
Helicopters Model MBB-BK 117 C-2 helicopters with certain part-numbered 
damper units installed. AD 2014-13-01 required either repairing the 
damper unit, replacing the damper unit with a repaired damper unit, or 
deactivating the rescue hoist system.
    AD 2014-13-01 was prompted by AD No. 2014-0057, dated March 6, 
2014, and corrected March 7, 2014, issued by EASA, which is the 
Technical Agent for the Member States of the European Union. EASA 
advised that a damper unit detached from the cable when the hoist 
damper was lifted by hand with no load attached. According to EASA, the 
retaining ring inside the damper unit was not located in the proper 
position because of a maintenance error or as a result of interference 
with the bonding strap unit during normal use. To address this unsafe 
condition, EASA AD No. 2014-0057 required modifying the bonding strap 
unit installation with an improved retaining ring and post-modification 
repetitive inspection.

Actions Since AD 2014-13-01 Was Issued

    Since we issued AD 2014-13-01, a damper unit with the improved 
retaining ring detached from its strap. Additionally, this damper unit 
was approved for installation on Airbus Helicopters Model MBB-BK 117 D-
2 helicopters. EASA issued Emergency AD No. 2015-0019-E, dated February 
5, 2015, which superseded EASA AD No. 2014-0057, to add Model MBB-BK117 
D-2 helicopters to the applicability. Airbus subsequently introduced a 
new single-piece retainer part number (P/N) B851M2060201 to strengthen 
the interconnection of the damper unit and attached cable.
    EASA has revised Emergency AD No. 2015-0019-E by issuing EASA AD 
No. 2015-0019R1, dated February 13, 2015, for Model MBB-BK117 C-2 and 
MBB-BK117 D-2 helicopters with a Goodrich external mounted hoist. EASA 
AD No. 2015-0019R1 introduces installation of single-piece retainer P/N 
B851M2060201 as an option for compliance and allows installation of 
damper units provided if equipped with the new single-piece retainer.

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 these same 
type designs.

Related Service Information Under 1 CFR Part 51

    We reviewed Airbus Helicopters Emergency Alert Service Bulletin 
(ASB) No. ASB MBB-BK117 C-2-85A-041, Revision 4, dated February 12, 
2015, for Model MBB-BK 117 C-2 helicopters and Emergency ASB No. ASB 
MBB-BK117 D-2-85A-002, Revision 1, dated February 12, 2015, for Model 
MBB-BK 117 D-2 helicopters. These Emergency ASBs specify replacing the 
split retainers with a single-piece retainer and re-identifying the 
damper housing.
    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 hoist operation, either replacing 
the damper unit with a unit that has been repaired in accordance with 
the service information, deactivating the rescue hoist, or replacing 
each split retainer with a single-piece retainer and marking the damper 
housing in accordance with the service information.

Costs of Compliance

    We estimate that this AD affects 137 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. We 
estimate it takes 1 work-hour to replace a damper unit and $8,715 for 
the required parts for a total cost of $8,800 per helicopter. We 
estimate it takes 0.5 work-hour to deactivate a rescue hoist for a 
total cost of $43 per helicopter. We estimate it takes 2 work-hours to 
replace the split retainer with a single-piece retainer and $171 for 
the required parts for a total cost of $341 per helicopter.

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 the required corrective 
actions must be completed 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.
