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.
This AD becomes effective July 15, 2014.
The Director of the Federal Register approved the incorporation by reference of a certain document listed in this AD as of July 15, 2014.
We must receive comments on this AD by August 29, 2014.

Start Supplemental Information
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.
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.
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.
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.
We consider this AD to be an interim action. If final action is later identified, we might consider further rulemaking then.Start Printed 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.
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.
