Download as PDF 70438 Federal Register / Vol. 79, No. 228 / Wednesday, November 26, 2014 / Rules and Regulations VI—DESCRIPTION OF SCORECARD MEASURES Scorecard measures 1 Description * * (2) Top 20 Counterparty Exposure/ Tier 1 Capital and Reserves. * * * * * Sum of the 20 largest total exposure amounts to counterparties divided by Tier 1 capital and reserves. The total exposure amount is equal to the sum of the institution’s exposure amounts to one counterparty (or borrower) for derivatives, securities financing transactions (SFTs), and cleared transactions, and its gross lending exposure (including all unfunded commitments) to that counterparty (or borrower). A counterparty includes an entity’s own affiliates. Exposures to entities that are affiliates of each other are treated as exposures to one counterparty (or borrower). Counterparty exposure excludes all counterparty exposure to the U.S. government and departments or agencies of the U.S. government that is unconditionally guaranteed by the full faith and credit of the United States. The exposure amount for derivatives, including OTC derivatives, cleared transactions that are derivative contracts, and netting sets of derivative contracts, must be calculated using the methodology set forth in 12 CFR 324.34(a), but without any reduction for collateral other than cash collateral that is all or part of variation margin and that satisfies the requirements of 12 CFR 324.10(c)(4)(ii)(C)(1)–(7). The exposure amount associated with SFTs, including cleared transactions that are SFTs, must be calculated using the standardized approach set forth in 12 CFR 324.37(b) or (c). For both derivatives and SFT exposures, the exposure amount to central counterparties must also include the default fund contribution.2 The largest total exposure amount to one counterparty divided by Tier 1 capital and reserves. The total exposure amount is equal to the sum of the institution’s exposure amounts to one counterparty (or borrower) for derivatives, SFTs, and cleared transactions, and its gross lending exposure (including all unfunded commitments) to that counterparty (or borrower). A counterparty includes an entity’s own affiliates. Exposures to entities that are affiliates of each other are treated as exposures to one counterparty (or borrower). Counterparty exposure excludes all counterparty exposure to the U.S. government and departments or agencies of the U.S. government that is unconditionally guaranteed by the full faith and credit of the United States. The exposure amount for derivatives, including OTC derivatives, cleared transactions that are derivative contracts, and netting sets of derivative contracts, must be calculated using the methodology set forth in 12 CFR 324.34(a), but without any reduction for collateral other than cash collateral that is all or part of variation margin and that satisfies the requirements of 12 CFR 324.10(c)(4)(ii)(C)(1)–(7). The exposure amount associated with SFTs, including cleared transactions that are SFTs, must be calculated using the standardized approach set forth in 12 CFR 324.37(b) or (c). For both derivatives and SFT exposures, the exposure amount to central counterparties must also include the default fund contribution.2 (3) Largest Counterparty Exposure/ Tier 1 Capital and Reserves. * * * * * * * 1 The FDIC retains the flexibility, as part of the risk-based assessment system, without the necessity of additional notice-and-comment rulemaking, to update the minimum and maximum cutoff values for all measures used in the scorecard (except for the Top 20 counterparty exposure to Tier 1 capital and reserves ratio and the largest counterparty exposure to Tier 1 capital and reserves ratio). The FDIC may update the minimum and maximum cutoff values for the higher-risk assets to Tier 1 capital and reserves ratio in order to maintain an approximately similar distribution of higher-risk assets to Tier 1 capital and reserves ratio scores as reported prior to April 1, 2013, or to avoid changing the overall amount of assessment revenue collected. 76 FR 10672, 10700 (February 25, 2011). The FDIC will review changes in the distribution of the higher-risk assets to Tier 1 capital and reserves ratio scores and the resulting effect on total assessments and risk differentiation between banks when determining changes to the cutoffs. The FDIC may update the cutoff values for the higher-risk assets to Tier 1 capital and reserves ratio more frequently than annually. The FDIC will provide banks with a minimum one quarter advance notice of changes in the cutoff values for the higher-risk assets to Tier 1 capital and reserves ratio with their quarterly deposit insurance invoice. 2 SFTs include repurchase agreements, reverse repurchase agreements, security lending and borrowing, and margin lending transactions, where the value of the transactions depends on market valuations and the transactions are often subject to margin agreements. The default fund contribution is the funds contributed or commitments made by a clearing member to a central counterparty’s mutualized loss sharing arrangement. The other terms used in this description are as defined in 12 CFR part 324, subparts A and D, unless defined otherwise in 12 CFR part 327. * * * * * DEPARTMENT OF TRANSPORTATION By order of the Board of Directors.

SUPPLEMENTARY INFORMATION: mstockstill on DSK4VPTVN1PROD with RULES Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Bombardier, Inc. Model DHC–8–400 series airplanes. The NPRM published in the Federal Register on April 9, 2014 (79 FR 19546). Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2013–35, dated November 15, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc. Model DHC–8–400 series airplanes. The MCAI states: There have been incidents of the ‘‘ENG FUEL PRESS’’ caution light illuminating inflight. An investigation revealed the engine fuel feed ejector pump swing arm assembly became detached from the outlet port of the engine fuel feed ejector pump and partially blocked the engine fuel feed line. If the failed swing arm assembly migrates along the fuel line downstream of the Fuel Tank AUX Pump junction, it could block the engine fuel flow and the affected engine may experience a flameout condition. Bombardier issued Service Bulletin (SB) 84–28–16 to introduce a restrictor into the VerDate Sep<11>2014 16:25 Nov 25, 2014 Jkt 235001 engine fuel feed line that is designed to contain a detached ejector pump swing arm assembly. This [Canadian] AD mandates the installation of a restrictor into the engine fuel feed line to prevent possible engine flameout. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov/#!documentDetail; D=FAA-2014-0191-0002. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (79 FR 19546, April 9, 2014) and the FAA’s response to each comment. Request To Require Compliance With Relevant Instructions in Service Information Horizon Air asked that we revise the NPRM (79 FR 19546, April 9, 2014) to specify only those instructions required to correct the unsafe condition. Horizon Air explained that paragraph (g) of the NPRM is more restrictive than necessary to ensure safety of flight, and that the Accomplishment Instructions of Bombardier Service Bulletin 84–28–16, Revision B, dated June 17, 2013, should not be mandated in its entirety. Horizon Air stated that the job set-up and closeout sections of the Accomplishment Instructions do not directly correct the unsafe condition; incorporating those sections as a requirement of the AD restricts an operator’s ability to perform other maintenance, in conjunction with incorporation of the instructions in the service information. We agree to refer only to the procedures that address the identified unsafe condition. We have revised paragraph (g) of this AD to refer paragraph 3.B., ‘‘Procedure,’’ of the Accomplishment Instructions of Bombardier Service Bulletin 84–28–16, Revision B, dated June 17, 2013. Request To Remove Repair Approval Language Horizon Air asked that we remove the ‘‘Airworthy Product’’ language in paragraph (i)(2) of the NPRM (79 FR 19546, April 9, 2014), which states, in part, ‘‘For a repair method to be approved, the repair approval must specifically refer to this AD.’’ Horizon Air stated that this sentence should not be included in the final rule, or at the very least it should be modified, because it will place an unnecessary regulatory burden on operators with airplanes built in Canada. Horizon Air added that Transport Canada Civil Aviation is the State holding design authority for Bombardier Model DHC– PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 70439 8–400 series airplanes; the NPRM simply restates the requirements of the TCCA AD. Horizon Air noted that any repairs created by Bombardier would have to be in compliance with the TCAA AD, and the repair would specifically refer to the TCCA AD. Horizon Air also stated that the bilateral agreement between Canada and the United States accepts documents approved by TCAA as meeting the requirements for FAA approval. Horizon Air does not see the need for referencing the U.S. AD number when the repair is approved by TCCA and refers to the Canadian AD; therefore, the repair meets the approval requirements from the State holding the Design Authority. Horizon Air concluded that if this requirement is retained, it would force operators to go back to the manufacturer and request a revision to the repair method to add the U.S. AD number, even if the repair method is referenced in the TCCA AD. We concur with the commenter’s request to remove the requirement to refer to this AD in repair approvals. Since late 2006, we have included the paragraph titled ‘‘Airworthy Product’’ in all MCAI ADs in which the FAA develops an AD based on a foreign authority’s AD. The MCAI or referenced service information in an FAA AD often directs the owner/operator to contact the manufacturer for corrective actions, such as a repair. Briefly, the Airworthy Product paragraph allowed owners/ operators to use corrective actions provided by the manufacturer if those actions were FAA-approved. In addition, the paragraph stated that any actions approved by the State of Design Authority (or its delegated agent) are considered to be FAA-approved. In the NPRM (79 FR 19546, April 9, 2014), we proposed to prevent the use of repairs that were not specifically developed to correct the unsafe condition, by requiring that the repair approval provided by the State of Design Authority or its delegated agent specifically refer to this FAA AD. This change was intended to clarify the method of compliance and to provide operators with better visibility of repairs that are specifically developed and approved to correct the unsafe condition. In addition, we proposed to change the phrase ‘‘its delegated agent’’ to include a design approval holder (DAH) with State of Design Authority design organization approval (DOA), as applicable, to refer to a DAH authorized to approve required repairs for the proposed AD. In addition to Horizon Air’s comments to the NPRM (79 FR 19546, April 9, 2014) about these proposed E:\FR\FM\26NOR1.SGM 26NOR1 mstockstill on DSK4VPTVN1PROD with RULES 70440 Federal Register / Vol. 79, No. 228 / Wednesday, November 26, 2014 / Rules and Regulations changes, a comment was provided for an NPRM having Directorate Identifier 2012–NM–101–AD (78 FR 78285, December 26, 2013). The commenter stated the following: ‘‘The proposed wording, being specific to repairs, eliminates the interpretation that Airbus messages are acceptable for approving minor deviations (corrective actions) needed during accomplishment of an AD mandated Airbus service bulletin.’’ This comment has made the FAA aware that some operators have misunderstood or misinterpreted the Airworthy Product paragraph to allow the owner/operator to use messages provided by the manufacturer as approval of deviations during the accomplishment of an AD-mandated action. The Airworthy Product paragraph does not approve messages or other information provided by the manufacturer for deviations to the requirements of the AD-mandated actions. The Airworthy Product paragraph only addresses the requirement to contact the manufacturer for corrective actions for the identified unsafe condition and does not cover deviations from other AD requirements. However, deviations to AD-required actions are addressed in 14 CFR 39.17, and anyone may request the approval for an alternative method of compliance to the AD-required actions using the procedures found in 14 CFR 39.19. To address this misunderstanding and misinterpretation of the Airworthy Product paragraph, we have changed the paragraph and retitled it ‘‘Contacting the Manufacturer.’’ This paragraph now clarifies that for any requirement in this AD to obtain corrective actions from a manufacturer, the actions must be accomplished using a method approved by the FAA, TCCA, or Bombardier, Inc.’s TCCA Design Approval Organization (DAO). The Contacting the Manufacturer paragraph also clarifies that, if approved by the DAO, the approval must include the DAO-authorized signature. The DAO signature indicates that the data and information contained in the document are TCCA-approved, which is also FAAapproved. Messages and other information provided by the manufacturer that does not contain the DAO-authorized signature approval are not TCCA-approved, unless TCCA directly approves the manufacturer’s message or other information. This clarification does not remove flexibility previously afforded by the Airworthy Product paragraph. Consistent with long-standing FAA policy, such flexibility was never intended for required actions. This is also consistent with the VerDate Sep<11>2014 16:25 Nov 25, 2014 Jkt 235001 recommendation of the Airworthiness Directive Implementation Aviation Rulemaking Committee to increase flexibility in complying with ADs by identifying those actions in manufacturers’ service instructions that are ‘‘Required for Compliance’’ with ADs. We continue to work with manufacturers to implement this recommendation. But once we determine that an action is required, any deviation from the requirement must be approved as an alternative method of compliance. Other commenters to the NPRM having Directorate Identifier 2012–NM– 101–AD (78 FR 78285, December 26, 2013) pointed out that in many cases the foreign manufacturer’s service bulletin and the foreign authority’s MCAI might have been issued some time before the FAA AD. Therefore, the DOA might have provided U.S. operators with an approved repair, developed with full awareness of the unsafe condition, before the FAA AD is issued. Under these circumstances, to comply with the FAA AD, the operator would be required to go back to the manufacturer’s DOA and obtain a new approval document, adding time and expense to the compliance process with no safety benefit. Based on these comments, we removed the requirement that the DAHprovided repair specifically refer to this AD. Before adopting such a requirement, the FAA will coordinate with affected DAHs and verify they are prepared to implement means to ensure that their repair approvals consider the unsafe condition addressed in this AD. Any such requirements will be adopted through the normal AD rulemaking process, including notice-and-comment procedures, when appropriate. We also have decided not to include a generic reference to either the ‘‘delegated agent’’ or ‘‘DAH with State of Design Authority design organization approval,’’ but instead we have provided the specific delegation approval granted by the State of Design Authority for the DAH throughout this AD. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these changes: • Are consistent with the intent that was proposed in the NPRM (79 FR 19546, April 9, 2014) for correcting the unsafe condition; and PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 • Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 19546, April 9, 2014). We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Costs of Compliance We estimate that this AD affects 81 airplanes of U.S. registry. We estimate the following costs to comply with this AD. We also estimate that it takes about 12 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts cost about $0 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $82,620, or $1,020 per product. 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 above, I certify that this AD: 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; and E:\FR\FM\26NOR1.SGM 26NOR1 Federal Register / Vol. 79, No. 228 / Wednesday, November 26, 2014 / Rules and Regulations 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.

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Bombardier, Inc. 
Model DHC-8-400 series airplanes. The NPRM published in the Federal 
Register on April 9, 2014 (79 FR 19546).
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2013-35, dated November 15, 2013 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for certain Bombardier, Inc. Model DHC-8-
400 series airplanes. The MCAI states:

    There have been incidents of the ``ENG FUEL PRESS'' caution 
light illuminating in-flight. An investigation revealed the engine 
fuel feed ejector pump swing arm assembly became detached from the 
outlet port of the engine fuel feed ejector pump and partially 
blocked the engine fuel feed line. If the failed swing arm assembly 
migrates along the fuel line downstream of the Fuel Tank AUX Pump 
junction, it could block the engine fuel flow and the affected 
engine may experience a flameout condition.
    Bombardier issued Service Bulletin (SB) 84-28-16 to introduce a 
restrictor into the engine fuel feed line that is designed to 
contain a detached ejector pump swing arm assembly.
    This [Canadian] AD mandates the installation of a restrictor 
into the engine fuel feed line to prevent possible engine flameout.

    You may examine the MCAI in the AD docket on the Internet at https://www.regulations.gov/#!documentDetail;D=FAA-2014-0191-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (79 
FR 19546, April 9, 2014) and the FAA's response to each comment.

Request To Require Compliance With Relevant Instructions in Service 
Information

    Horizon Air asked that we revise the NPRM (79 FR 19546, April 9, 
2014) to specify only those instructions required to correct the unsafe 
condition. Horizon Air explained that paragraph (g) of the NPRM is more 
restrictive than necessary to ensure safety of flight, and that the 
Accomplishment Instructions of Bombardier Service Bulletin 84-28-16, 
Revision B, dated June 17, 2013, should not be mandated in its 
entirety. Horizon Air stated that the job set-up and close-out sections 
of the Accomplishment Instructions do not directly correct the unsafe 
condition; incorporating those sections as a requirement of the AD 
restricts an operator's ability to perform other maintenance, in 
conjunction with incorporation of the instructions in the service 
information.
    We agree to refer only to the procedures that address the 
identified unsafe condition. We have revised paragraph (g) of this AD 
to refer paragraph 3.B., ``Procedure,'' of the Accomplishment 
Instructions of Bombardier Service Bulletin 84-28-16, Revision B, dated 
June 17, 2013.

Request To Remove Repair Approval Language

    Horizon Air asked that we remove the ``Airworthy Product'' language 
in paragraph (i)(2) of the NPRM (79 FR 19546, April 9, 2014), which 
states, in part, ``For a repair method to be approved, the repair 
approval must specifically refer to this AD.'' Horizon Air stated that 
this sentence should not be included in the final rule, or at the very 
least it should be modified, because it will place an unnecessary 
regulatory burden on operators with airplanes built in Canada. Horizon 
Air added that Transport Canada Civil Aviation is the State holding 
design authority for Bombardier Model DHC-8-400 series airplanes; the 
NPRM simply restates the requirements of the TCCA AD. Horizon Air noted 
that any repairs created by Bombardier would have to be in compliance 
with the TCAA AD, and the repair would specifically refer to the TCCA 
AD. Horizon Air also stated that the bilateral agreement between Canada 
and the United States accepts documents approved by TCAA as meeting the 
requirements for FAA approval. Horizon Air does not see the need for 
referencing the U.S. AD number when the repair is approved by TCCA and 
refers to the Canadian AD; therefore, the repair meets the approval 
requirements from the State holding the Design Authority. Horizon Air 
concluded that if this requirement is retained, it would force 
operators to go back to the manufacturer and request a revision to the 
repair method to add the U.S. AD number, even if the repair method is 
referenced in the TCCA AD.
    We concur with the commenter's request to remove the requirement to 
refer to this AD in repair approvals. Since late 2006, we have included 
the paragraph titled ``Airworthy Product'' in all MCAI ADs in which the 
FAA develops an AD based on a foreign authority's AD. The MCAI or 
referenced service information in an FAA AD often directs the owner/
operator to contact the manufacturer for corrective actions, such as a 
repair. Briefly, the Airworthy Product paragraph allowed owners/
operators to use corrective actions provided by the manufacturer if 
those actions were FAA-approved. In addition, the paragraph stated that 
any actions approved by the State of Design Authority (or its delegated 
agent) are considered to be FAA-approved.
    In the NPRM (79 FR 19546, April 9, 2014), we proposed to prevent 
the use of repairs that were not specifically developed to correct the 
unsafe condition, by requiring that the repair approval provided by the 
State of Design Authority or its delegated agent specifically refer to 
this FAA AD. This change was intended to clarify the method of 
compliance and to provide operators with better visibility of repairs 
that are specifically developed and approved to correct the unsafe 
condition. In addition, we proposed to change the phrase ``its 
delegated agent'' to include a design approval holder (DAH) with State 
of Design Authority design organization approval (DOA), as applicable, 
to refer to a DAH authorized to approve required repairs for the 
proposed AD.
    In addition to Horizon Air's comments to the NPRM (79 FR 19546, 
April 9, 2014) about these proposed

[[Page 70440]]

changes, a comment was provided for an NPRM having Directorate 
Identifier 2012-NM-101-AD (78 FR 78285, December 26, 2013). The 
commenter stated the following: ``The proposed wording, being specific 
to repairs, eliminates the interpretation that Airbus messages are 
acceptable for approving minor deviations (corrective actions) needed 
during accomplishment of an AD mandated Airbus service bulletin.''
    This comment has made the FAA aware that some operators have 
misunderstood or misinterpreted the Airworthy Product paragraph to 
allow the owner/operator to use messages provided by the manufacturer 
as approval of deviations during the accomplishment of an AD-mandated 
action. The Airworthy Product paragraph does not approve messages or 
other information provided by the manufacturer for deviations to the 
requirements of the AD-mandated actions. The Airworthy Product 
paragraph only addresses the requirement to contact the manufacturer 
for corrective actions for the identified unsafe condition and does not 
cover deviations from other AD requirements. However, deviations to AD-
required actions are addressed in 14 CFR 39.17, and anyone may request 
the approval for an alternative method of compliance to the AD-required 
actions using the procedures found in 14 CFR 39.19.
    To address this misunderstanding and misinterpretation of the 
Airworthy Product paragraph, we have changed the paragraph and retitled 
it ``Contacting the Manufacturer.'' This paragraph now clarifies that 
for any requirement in this AD to obtain corrective actions from a 
manufacturer, the actions must be accomplished using a method approved 
by the FAA, TCCA, or Bombardier, Inc.'s TCCA Design Approval 
Organization (DAO).
    The Contacting the Manufacturer paragraph also clarifies that, if 
approved by the DAO, the approval must include the DAO-authorized 
signature. The DAO signature indicates that the data and information 
contained in the document are TCCA-approved, which is also FAA-
approved. Messages and other information provided by the manufacturer 
that does not contain the DAO-authorized signature approval are not 
TCCA-approved, unless TCCA directly approves the manufacturer's message 
or other information.
    This clarification does not remove flexibility previously afforded 
by the Airworthy Product paragraph. Consistent with long-standing FAA 
policy, such flexibility was never intended for required actions. This 
is also consistent with the recommendation of the Airworthiness 
Directive Implementation Aviation Rulemaking Committee to increase 
flexibility in complying with ADs by identifying those actions in 
manufacturers' service instructions that are ``Required for 
Compliance'' with ADs. We continue to work with manufacturers to 
implement this recommendation. But once we determine that an action is 
required, any deviation from the requirement must be approved as an 
alternative method of compliance.
    Other commenters to the NPRM having Directorate Identifier 2012-NM-
101-AD (78 FR 78285, December 26, 2013) pointed out that in many cases 
the foreign manufacturer's service bulletin and the foreign authority's 
MCAI might have been issued some time before the FAA AD. Therefore, the 
DOA might have provided U.S. operators with an approved repair, 
developed with full awareness of the unsafe condition, before the FAA 
AD is issued. Under these circumstances, to comply with the FAA AD, the 
operator would be required to go back to the manufacturer's DOA and 
obtain a new approval document, adding time and expense to the 
compliance process with no safety benefit.
    Based on these comments, we removed the requirement that the DAH-
provided repair specifically refer to this AD. Before adopting such a 
requirement, the FAA will coordinate with affected DAHs and verify they 
are prepared to implement means to ensure that their repair approvals 
consider the unsafe condition addressed in this AD. Any such 
requirements will be adopted through the normal AD rulemaking process, 
including notice-and-comment procedures, when appropriate.
    We also have decided not to include a generic reference to either 
the ``delegated agent'' or ``DAH with State of Design Authority design 
organization approval,'' but instead we have provided the specific 
delegation approval granted by the State of Design Authority for the 
DAH throughout this AD.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these changes:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 19546, April 9, 2014) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 19546, April 9, 2014).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Costs of Compliance

    We estimate that this AD affects 81 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD.
    We also estimate that it takes about 12 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts cost about $0 per product. Based 
on these figures, we estimate the cost of this AD on U.S. operators to 
be $82,620, or $1,020 per product.

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 above, I certify that this AD:
    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; and

[[Page 70441]]

    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.
