Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).

This proposed AD would require establishing or reducing the life limit of various parts. This proposed AD is prompted by recalculations. The actions of this proposed AD are intended to address an unsafe condition on these products.
DATES: We must receive comments on this proposed AD by January 18, 2019.
ADDRESSES: You may send comments by any of the following methods:

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 might result from adopting the proposals in this document. The most helpful comments reference a specific portion of the proposal, 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 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 proposed rulemaking. Before acting on this proposal, we will consider all comments we receive on or before the closing date for comments. We will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. We may change this proposal in light of the comments we receive.
EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2017-0174, dated September 12, 2017 (EASA AD 2017-0174), to correct an unsafe condition for Airbus Helicopters Model MBB-BK 117 C-2 helicopters. EASA advises that recalculation by Airbus Helicopters has resulted in new or reduced life limits for certain parts. EASA AD 2017-0174 states the life limits are mandatory for continued airworthiness and failing to replace life-
limited parts as specified could result in an unsafe condition. To address this condition, EASA AD 2017-0174 requires replacing the affected parts before exceeding their new or reduced life limit.
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 its AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other products of the same type design.
Related Service Information
We reviewed Airbus Helicopters Alert Service Bulletin ASB MBB-BK117 C-2-04A-008, Revision 0, dated April 27, 2017, for Model MBB-BK 117 C-2 and C-2e helicopters. This service information specifies entering into the helicopter records the reduced and new airworthiness life limits for certain part-numbered main rotor head, swash plate, rotor flight controls, cyclic controls, and upper controls parts.
Proposed AD Requirements
This proposed AD would require establishing and reducing the life limit of the following parts: Main rotor head--nut, upper and lower quadruple nut, bolts, and inner sleeve; swash plate control ring assembly; rotor flight control collective bellcrank-K; cyclic
control rod tube; and upper control forked lever.
Costs of Compliance
We estimate that this proposed AD would affect 128 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.
Replacing a nut would take about 5 work-hours and parts would cost about $3,352 for an estimated replacement cost of $3,777.
Replacing a quadruple nut upper would take about 5 work-hours and parts would cost about $3,283 for an estimated replacement cost of $3,708.
Replacing a quadruple nut lower would take about 5 work-hours and parts would cost about $3,405 for an estimated replacement cost of $3,830.
Replacing a bolt would take about 2 work-hours and parts would cost about $370 for an estimated replacement cost of $540.
Replacing an inner sleeve would take about 2 work-hours and parts would cost about $20,073 for an estimated replacement cost of $20,243.
Replacing a control ring assembly would take about 5 work-hours and parts would cost about $11,141 for an estimated replacement cost of $11,566.
Replacing a bellcrank-K (collective) would take about 4 work-hours and parts would cost about $3,400 for an estimated replacement cost of $3,740.
Replacing a control rod tube would take about 4 work-hours and parts would cost about $1,084 for an estimated replacement cost of $1,424.
Replacing a forked lever would take about 3 work-hours and parts would cost about $6,049 for an estimated replacement cost of $6,304.
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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation:
Is not a ``significant regulatory action'' under Executive Order 12866;
Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);
Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; and
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 proposed AD and placed it in the AD docket.

The Proposed Amendment
Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 Amended
The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD):
Airbus Helicopters Deutschland GmbH: Docket No. FAA-2018-0980; Product Identifier 2017-SW-123-AD.
This AD applies to Airbus Helicopters Deutschland GmbH Model MBB-BK 117 C-2 helicopters with a part listed in Table 1 to paragraph (e) of this AD installed, certificated in any category.
Note 1 to paragraph (a) of this AD: Helicopters with an MBB-
BK117 C-2e designation are Model MBB-BK117 C-2 helicopters.
(b) Unsafe Condition
This AD defines the unsafe condition as a part remaining in service beyond its fatigue life. This condition could result in failure of a part and loss of control of the helicopter.
(c) Comments Due Date
We must receive comments by January 18, 2019.
You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time.
(e) Required Actions
Before further flight, remove from service any part that has reached or exceeded its new or reduced life limit as listed in Table 1 to paragraph (e) of this AD. Thereafter, remove from service each part on or before reaching its new or reduced life limit as listed in Table 1 to paragraph (e) of this AD. For purposes of this AD, a ``landing'' is counted any time the helicopter lifts off into the air and then lands again regardless of the duration of the landing and regardless of whether the engine is shut down.
