Download as PDF Federal Register / Vol. 80, No. 60 / Monday, March 30, 2015 / Proposed Rules National Credit Union Administration, Office of Information and Regulatory Affairs, Washington, DC 20503. § 701.36 Federal credit union occupancy, planning, and disposal of acquired and abandoned premises. C. Executive Order 13132 (a) Scope. Section 107(4) of the Federal Credit Union Act (12 U.S.C. 1757(4)) authorizes a federal credit union to purchase, hold, and dispose of property necessary or incidental to its operations. This section interprets and implements that provision by establishing occupancy, planning, and disposal requirements for acquired and abandoned premises, and by prohibiting certain transactions. This section applies only to federal credit unions. * * * * * ■ 3. Revise § 701.36 paragraph (b) by removing the following definitions: ‘‘fixed assets’’, ‘‘furniture, fixtures, and equipment’’, ‘‘investments in fixed assets’’, ‘‘retained earnings’’, and ‘‘shares’’. ■ 4. Remove § 701.36 paragraph (c). ■ 5. Revise § 701.36 paragraph (d)(2) to read as follows: (d) * * * (2) If a federal credit union acquires premises for future expansion, including unimproved land or unimproved real property, it must partially occupy them within a reasonable period, but no later than six years after the date of acquisition. NCUA may waive the partial occupation requirements. To seek a waiver, a federal credit union must submit a written request to its Regional Office and fully explain why it needs the waiver. The Regional Director will provide the federal credit union a written response, either approving or disapproving the request. The Regional Director’s decision will be based on safety and soundness considerations. * * * * * ■ 6. In § 701.36 redesignate paragraph (d) as paragraph (c) and paragraph (e) as paragraph (d). Executive Order 13132 encourages independent regulatory agencies to consider the impact of their actions on state and local interests. NCUA, an independent regulatory agency, as defined in 44 U.S.C. 3502(5), voluntarily complies with the executive order to adhere to fundamental federalism principles. Because the fixed assets regulation applies only to FCUs, the 2015 proposal 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. As such, NCUA has determined that this rule does not constitute a policy that has federalism implications for purposes of the executive order. D. Assessment of Federal Regulations and Policies on Families NCUA has determined that this rule will not affect family well-being within the meaning of Section 654 of the Treasury and General Government Appropriations Act of 1999.34 List of Subjects in 12 CFR Part 701 Credit unions, Reporting and recordkeeping requirements. By the National Credit Union Administration Board, on March 19, 2015. Gerard Poliquin, Secretary of the Board. For the reasons stated above, NCUA proposes to amend 12 CFR 701.36 as follows: PART 701—ORGANIZATION AND OPERATION OF FEDERAL CREDIT 1. The authority for part 701 continues to read as follows: tkelley on DSK3SPTVN1PROD with PROPOSALS ■ Authority: 12 U.S.C. 1752(5), 1757, 1765, 1757, 1758, 1759, 1761a, 1761b, 1766, 1767, 1782, 1784, 1786, 1787, 1789.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede airworthiness directive (AD) 2014–05– 06 for certain Eurocopter Deutschland GmbH (ECD) (now Airbus Helicopters Deutschland GmbH) Model EC135 and MBB–BK 117 C–2 helicopters to correct an error. AD 2014–05–06 currently requires inspecting the flight-control bearings repetitively, replacing any loose bearing with an airworthy flightcontrol bearing, and installing bushings and washers. This proposed AD would require the same actions. This proposed AD results from the discovery of an error in the compliance time for AD 2014–05–06. These proposed actions are intended to prevent the affected control lever from shifting, contacting the helicopter structure, and reducing control of the helicopter.

SUPPLEMENTARY INFORMATION: tkelley on DSK3SPTVN1PROD with PROPOSALS Comments Invited 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. Discussion On February 20, 2014, we issued AD 2014–05–06, Amendment 39–17779 (79 FR 13196, March 10, 2014), for certain VerDate Sep<11>2014 17:11 Mar 27, 2015 Jkt 235001 ECD (now Airbus Helicopters Deutschland GmbH) Model EC135 and MBB–BK 117 C–2 helicopters. AD 2014–05–06 requires inspecting the flight-control bearings repetitively, replacing any loose bearing with an airworthy flight-control bearing, and installing bushings and washers. AD 2014–05–06 was prompted by the discovery of loose flight control bearings because of incorrect installation. This condition, if not corrected, could result in the affected control lever shifting, contacting the helicopter structure, and reducing control of the helicopter. Actions Since AD 2014–05–06 Was Issued Since we issued AD 2014–05–06 (79 FR 13196, March 10, 2014), we discovered an error regarding the compliance time for certain model helicopters. Paragraph (e)(1)(i) should have required that certain actions be accomplished within the next 100 hours time-in-service or at the next annual inspection, whichever occurs first. However, we omitted the word ‘‘first’’ from that sentence, which changes the meaning of the required compliance time. Also since we issued AD 2014–05–06, ECD changed its name to Airbus Helicopters Deutschland GmbH. This proposed AD reflects that change and updates the contact information to obtain service documentation. 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 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 Under 1 CFR Part 51 ECD, now called Airbus Helicopters, has issued Alert Service Bulletin (ASB) MBB BK117 C–2–67A–010, Revision 3, dated February 8, 2010, and ASB EC135–67A–019, Revision 3, dated December 16, 2009. These ASBs specify: • Within the next 50 flight hours (FHs), inspecting the affected bearings and, if necessary, rebonding any affected bearings or replacing the lever assembly. • Within 12 months, retrofitting bushings and washers on the levers to prevent movement of the bearings. PO 00000 Frm 00015 Fmt 4702 Sfmt 4702 • After the retrofit, repeating the inspection every 800 FHs or 36 months for the Model EC135 helicopters, whichever comes first, and 600 FHs or 24 months, whichever comes first, for the Model MBB–BK 117 C–2 helicopters. EASA classified these ASBs as mandatory and issued AD No. 2010– 0058 to ensure the continued airworthiness of these helicopters. 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 of this NPRM. Proposed AD Requirements For Airbus Model EC135 P1, P2, P2+, T1, T2, and T2+ helicopters this proposed AD would require: • Within the next 100 hours time-inservice (TIS) or at the next annual inspection, whichever occurs first, modifying the left-hand (LH) and righthand (RH) guidance units and the cyclic shaft by installing bushings and washers to prevent shifting of the bearings in the axial direction. • At intervals not to exceed 800 hours TIS or 36 months, whichever occurs first, inspecting the bearings in the LH guidance unit, RH guidance unit, cyclic control, upper guidance unit, and linear voltage differential transducer plate for play. If any bearing is loose, replacing the affected bearing with an airworthy bearing. For Model MBB–BK 117 C–2 helicopters, this proposed AD would require: • Within the next 100 hours TIS or at the next annual inspection, whichever occurs first, modifying the LH and RH guidance units and the lateral control lever by installing bushings and washers to prevent shifting of the bearings in the axial direction. • At intervals not to exceed 600 hours TIS or 24 months, whichever occurs first, inspecting the bearings in the RH guidance unit, LH guidance unit, and lateral control guidance unit for play. If any bearing is loose, replacing the affected bearing with an airworthy bearing. Differences Between This Proposed AD and the EASA AD Differences between this proposed AD and the EASA AD are: • The EASA AD is applicable to the EC 635 helicopter, whereas this proposed AD is not because the EC 635 helicopter is not type certificated in the U.S. • The EASA AD requires an initial inspection within 50 flight hours or one E:\FR\FM\30MRP1.SGM 30MRP1 Federal Register / Vol. 80, No. 60 / Monday, March 30, 2015 / Proposed Rules month, whichever occurs first after May 31, 2008, and a modification within the next 12 months. This proposed AD would require the modification within 100 hours TIS or at the next annual inspection, whichever occurs first, and no inspection until after the modification has been accomplished. • The EASA AD applies to all EC135 and MBB–BK 117 C–2 helicopters, while this proposed AD would apply to certain serial-numbered Model EC135 and Model MBB–BK 117 C–2 helicopters, as recommended by the appropriate ECD ASB. Costs of Compliance We estimate that this proposed AD would affect 175 Model EC135 and 112 Model MBB–BK 117 C–2 helicopters of U.S. Registry and that labor costs would average $85 per work-hour. Based on these estimates, we expect the following costs: • For EC135 helicopters, it would take about 32 work-hours to perform the modification. Parts would cost about $312. The total cost for the modification would be about $3,032 per helicopter and $530,600 for the U.S. operator fleet. The repetitive inspections would require 6.5 work-hours for a cost of about $553 per helicopter and about $96,775 for the fleet per inspection cycle. • For MBB–BK 117 C–2 helicopters, it would take about 32 work-hours to perform the modification. Parts would cost about $396. The total cost for the modification would be $3,116 per helicopter and $348,992 for the U.S. operator fleet. The cost for the repetitive inspections thereafter would be about $85 per helicopter and $9,520 for the fleet per inspection cycle. tkelley on DSK3SPTVN1PROD with PROPOSALS 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 VerDate Sep<11>2014 17:11 Mar 27, 2015 Jkt 235001 products identified in this rulemaking action. Regulatory Findings 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: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Is not a ‘‘significant rule’’ under the 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 proposed AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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 1.

06 for certain Eurocopter Deutschland GmbH (ECD) (now Airbus 
Helicopters Deutschland GmbH) Model EC135 and MBB-BK 117 C-2 
helicopters to correct an error. AD 2014-05-06 currently requires 
inspecting the flight-control bearings repetitively, replacing any 
loose bearing with an airworthy flight-control bearing, and installing 
bushings and washers. This proposed AD would require the same actions. 
This proposed AD results from the discovery of an error in the 
compliance time for AD 2014-05-06. These proposed actions are intended 
to prevent the affected control lever from shifting, contacting the 
helicopter structure, and reducing control of the helicopter.

Discussion

    On February 20, 2014, we issued AD 2014-05-06, Amendment 39-17779 
(79 FR 13196, March 10, 2014), for certain ECD (now Airbus Helicopters 
Deutschland GmbH) Model EC135 and MBB-BK 117 C-2 helicopters. AD 2014-
05-06 requires inspecting the flight-control bearings repetitively, 
replacing any loose bearing with an airworthy flight-control bearing, 
and installing bushings and washers. AD 2014-05-06 was prompted by the 
discovery of loose flight control bearings because of incorrect 
installation. This condition, if not corrected, could result in the 
affected control lever shifting, contacting the helicopter structure, 
and reducing control of the helicopter.

Actions Since AD 2014-05-06 Was Issued

    Since we issued AD 2014-05-06 (79 FR 13196, March 10, 2014), we 
discovered an error regarding the compliance time for certain model 
helicopters. Paragraph (e)(1)(i) should have required that certain 
actions be accomplished within the next 100 hours time-in-service or at 
the next annual inspection, whichever occurs first. However, we omitted 
the word ``first'' from that sentence, which changes the meaning of the 
required compliance time.
    Also since we issued AD 2014-05-06, ECD changed its name to Airbus 
Helicopters Deutschland GmbH. This proposed AD reflects that change and 
updates the contact information to obtain service documentation.

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 
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 Under 1 CFR Part 51

    ECD, now called Airbus Helicopters, has issued Alert Service 
Bulletin (ASB) MBB BK117 C-2-67A-010, Revision 3, dated February 8, 
2010, and ASB EC135-67A-019, Revision 3, dated December 16, 2009. These 
ASBs specify:
     Within the next 50 flight hours (FHs), inspecting the 
affected bearings and, if necessary, rebonding any affected bearings or 
replacing the lever assembly.
     Within 12 months, retrofitting bushings and washers on the 
levers to prevent movement of the bearings.
     After the retrofit, repeating the inspection every 800 FHs 
or 36 months for the Model EC135 helicopters, whichever comes first, 
and 600 FHs or 24 months, whichever comes first, for the Model MBB-BK 
117 C-2 helicopters.
    EASA classified these ASBs as mandatory and issued AD No. 2010-0058 
to ensure the continued airworthiness of these helicopters. 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 of this NPRM.

Proposed AD Requirements

    For Airbus Model EC135 P1, P2, P2+, T1, T2, and T2+ helicopters 
this proposed AD would require:
     Within the next 100 hours time-in-service (TIS) or at the 
next annual inspection, whichever occurs first, modifying the left-hand 
(LH) and right-hand (RH) guidance units and the cyclic shaft by 
installing bushings and washers to prevent shifting of the bearings in 
the axial direction.
     At intervals not to exceed 800 hours TIS or 36 months, 
whichever occurs first, inspecting the bearings in the LH guidance 
unit, RH guidance unit, cyclic control, upper guidance unit, and linear 
voltage differential transducer plate for play. If any bearing is 
loose, replacing the affected bearing with an airworthy bearing.
    For Model MBB-BK 117 C-2 helicopters, this proposed AD would 
require:
     Within the next 100 hours TIS or at the next annual 
inspection, whichever occurs first, modifying the LH and RH guidance 
units and the lateral control lever by installing bushings and washers 
to prevent shifting of the bearings in the axial direction.
     At intervals not to exceed 600 hours TIS or 24 months, 
whichever occurs first, inspecting the bearings in the RH guidance 
unit, LH guidance unit, and lateral control guidance unit for play. If 
any bearing is loose, replacing the affected bearing with an airworthy 
bearing.

Differences Between This Proposed AD and the EASA AD

    Differences between this proposed AD and the EASA AD are:
     The EASA AD is applicable to the EC 635 helicopter, 
whereas this proposed AD is not because the EC 635 helicopter is not 
type certificated in the U.S.
     The EASA AD requires an initial inspection within 50 
flight hours or one

[[Page 16605]]

month, whichever occurs first after May 31, 2008, and a modification 
within the next 12 months. This proposed AD would require the 
modification within 100 hours TIS or at the next annual inspection, 
whichever occurs first, and no inspection until after the modification 
has been accomplished.
     The EASA AD applies to all EC135 and MBB-BK 117 C-2 
helicopters, while this proposed AD would apply to certain serial-
numbered Model EC135 and Model MBB-BK 117 C-2 helicopters, as 
recommended by the appropriate ECD ASB.

Costs of Compliance

    We estimate that this proposed AD would affect 175 Model EC135 and 
112 Model MBB-BK 117 C-2 helicopters of U.S. Registry and that labor 
costs would average $85 per work-hour. Based on these estimates, we 
expect the following costs:
     For EC135 helicopters, it would take about 32 work-hours 
to perform the modification. Parts would cost about $312. The total 
cost for the modification would be about $3,032 per helicopter and 
$530,600 for the U.S. operator fleet. The repetitive inspections would 
require 6.5 work-hours for a cost of about $553 per helicopter and 
about $96,775 for the fleet per inspection cycle.
     For MBB-BK 117 C-2 helicopters, it would take about 32 
work-hours to perform the modification. Parts would cost about $396. 
The total cost for the modification would be $3,116 per helicopter and 
$348,992 for the U.S. operator fleet. The cost for the repetitive 
inspections thereafter would be about $85 per helicopter and $9,520 for 
the fleet per inspection cycle.

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 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:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the 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 proposed AD and placed it in the AD docket.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

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

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.
