Download as PDF 4012 Federal Register / Vol. 84, No. 31 / Thursday, February 14, 2019 / Proposed Rules position itself (e.g., the market value of private equity positions). 12 Currently, companies with significant trading activity include any bank holding company or intermediate holding company that (1) has aggregate trading assets and liabilities of $50 billion or more, or aggregate trading assets and liabilities equal to 10 percent or more of total consolidated assets, and (2) is not a large and noncomplex firm.. The Board may also subject a state member bank subsidiary of any such bank holding company to the market shock component. The set of companies subject to the market shock component could change over time as the size, scope, and complexity of financial company’s trading activities evolve. * * * * * 4. Approach for Formulating the Macroeconomic Assumptions for Scenarios a. This section describes the Board’s approach for formulating macroeconomic assumptions for each scenario. The methodologies for formulating this part of each scenario differ by scenario, so these methodologies for the baseline and severely adverse scenarios are described separately in each of the following subsections. b. In general, the baseline scenario will reflect the most recently available consensus views of the macroeconomic outlook expressed by professional forecasters, government agencies, and other public-sector organizations as of the beginning of the annual stress-test cycle. The severely adverse scenario will consist of a set of economic and financial conditions that reflect the conditions of post-war U.S. recessions. c. Each of these scenarios is described further in sections below as follows: Baseline (subsection 4.1) and severely adverse (subsection 4.2) 4.1 Approach for Formulating Macroeconomic Assumptions in the Baseline Scenario a. The stress test rules define the baseline scenario as a set of conditions that affect the U.S. economy or the financial condition of a banking organization, and that reflect the consensus views of the economic and financial outlook. Projections under a baseline scenario are used to evaluate how companies would perform in more likely economic and financial conditions. The baseline serves also as a point of comparison to the severely adverse scenario, giving some sense of how much of the company’s capital decline could be ascribed to the scenario as opposed to the company’s capital adequacy under expected conditions. * * * * * VerDate Sep<11>2014 17:17 Feb 13, 2019 Jkt 247001 4.2 Approach for Formulating the Macroeconomic Assumptions in the Severely Adverse Scenario The stress test rules define a severely adverse scenario as a set of conditions that affect the U.S. economy or the financial condition of a financial company and that overall are significantly more severe than those associated with the baseline scenario. The financial company will be required to publicly disclose a summary of the results of its stress test under the severely adverse scenario, and the Board intends to publicly disclose the results of its analysis of the financial company under the severely adverse scenario. * * * * * 5. Approach for Formulating the Market Shock Component a. This section discusses the approach the Board proposes to adopt for developing the market shock component of the severely adverse scenario appropriate for companies with significant trading activities. The design and specification of the market shock component differs from that of the macroeconomic scenarios because profits and losses from trading are measured in mark-to-market terms, while revenues and losses from traditional banking are generally measured using the accrual method. As noted above, another critical difference is the time-evolution of the market shock component. The market shock component consists of an instantaneous ‘‘shock’’ to a large number of risk factors that determine the mark-to-market value of trading positions, while the macroeconomic scenarios supply a projected path of economic variables that affect traditional banking activities over the entire planning period. b. The development of the market shock component that are detailed in this section are as follows: Baseline (subsection 5.1) and severely adverse (subsection 5.2). * * * * * 5.2.2 Approaches to Market Shock Design a. As an additional component of the severely adverse scenario, the Board plans to use a standardized set of market shocks that apply to all companies with significant trading activity. The market shocks could be based on a single historical episode, multiple historical periods, hypothetical (but plausible) events, or some combination of historical episodes and hypothetical events (hybrid approach). Depending on the type of hypothetical events, a scenario based on such events may PO 00000 Frm 00011 Fmt 4702 Sfmt 4702 result in changes in risk factors that were not previously observed. In the supervisory scenarios for 2012 and 2013, the shocks were largely based on relative moves in asset prices and rates during the second half of 2008, but also included some additional considerations to factor in the widening of spreads for European sovereigns and financial companies based on actual observation during the latter part of 2011. * * * * * By order of the Board of Governors of the Federal Reserve System, January 8, 2019.

VerDate Sep<11>2014 17:17 Feb 13, 2019 Jkt 247001 Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018–0184, dated August 28, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all ATR—GIE Avions de Transport Re´gional Model ATR72 airplanes. The MCAI states: The airworthiness limitations and certification maintenance requirements (CMR) for ATR aeroplanes, which are approved by EASA, are currently defined and published in the TLD [time limits document]. These instructions have been identified as mandatory for continued airworthiness. Failure to accomplish these instructions could result in an unsafe condition. Previously, EASA issued AD 2017–0223 (later revised) to require accomplishment of the actions specified in the TLD at Revision 15. Since EASA AD 2017–0223R1 [which corresponds to FAA AD 2018–14–11, Amendment 39–19331 (83 FR 34031, July 19, 2018)] was issued, ATR published Revision 16 of the TLD for ATR 72 aeroplanes, introducing new and/or more restrictive airworthiness limitations and/or maintenance actions. For the reasons described above, this [EASA] AD retains the requirements of EASA AD 2017–0223R1, which is superseded, and requires accomplishment of the actions specified in the TLD. This proposed AD would require revising the existing maintenance or inspection program to incorporate certain maintenance instructions and airworthiness limitations. The unsafe condition is fatigue cracking and damage in principal structural elements, which could result in reduced structural integrity of the airplane. You may examine the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2018– 1069. Relationship Between Proposed AD and AD 2018–14–11 This NPRM does not propose to supersede AD 2018–14–11. Rather, we have determined that a stand-alone AD is more appropriate to address the changes in the MCAI. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance instructions and airworthiness limitations. Accomplishment of the proposed actions would then terminate all of the requirements of AD 2018–14–11. PO 00000 Frm 00012 Fmt 4702 Sfmt 4702 4013 Related Service Information Under 1 CFR Part 51 ATR—GIE Avions de Transport Re´gional has issued ATR ATR72 Time Limits Document, Revision 16, dated January 30, 2018. This service information describes preventive maintenance requirements and includes updated limitations, tasks, thresholds and intervals to be incorporated into the maintenance or inspection program. 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. FAA’s Determination This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed Requirements of This NPRM This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or revised maintenance instructions and airworthiness limitations. This proposed AD would require revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this proposed AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (l)(1) of this proposed AD. Difference Between This Proposed AD and the MCAI The MCAI specifies that if there are findings from the airworthiness limitations section (ALS) inspection tasks, corrective actions must be accomplished in accordance with Avions de Transport Re´gional maintenance documentation. However, this proposed AD does not include that requirement. Operators of U.S.registered airplanes are required by E:\FR\FM\14FEP1.SGM 14FEP1 4014 Federal Register / Vol. 84, No. 31 / Thursday, February 14, 2019 / Proposed Rules general airworthiness and operational regulations to perform maintenance using methods that are acceptable to the FAA. We consider those methods to be adequate to address any corrective actions necessitated by the findings of ALS inspections required by this proposed AD. normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes and associated appliances to the Director of the System Oversight Division. Costs of Compliance Regulatory Findings We estimate that this proposed AD affects 23 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: We have determined that revising the existing maintenance or inspection program takes an average of 90 workhours per operator, although we recognize that this number may vary from operator to operator. In the past, we have estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), we have determined that a per-operator estimate is more accurate than a per-airplane estimate. Therefore, we estimate the total cost per operator to be $7,650 (90 work-hours x $85 per work-hour). 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 above, 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; 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. 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. This proposed AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is VerDate Sep<11>2014 17:17 Feb 13, 2019 Jkt 247001 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2018-0184, dated August 28, 2018 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all ATR--GIE Avions de Transport 
R[eacute]gional Model ATR72 airplanes. The MCAI states:

    The airworthiness limitations and certification maintenance 
requirements (CMR) for ATR aeroplanes, which are approved by EASA, 
are currently defined and published in the TLD [time limits 
document]. These instructions have been identified as mandatory for 
continued airworthiness.
    Failure to accomplish these instructions could result in an 
unsafe condition.
    Previously, EASA issued AD 2017-0223 (later revised) to require 
accomplishment of the actions specified in the TLD at Revision 15.
    Since EASA AD 2017-0223R1 [which corresponds to FAA AD 2018-14-
11, Amendment 39-19331 (83 FR 34031, July 19, 2018)] was issued, ATR 
published Revision 16 of the TLD for ATR 72 aeroplanes, introducing 
new and/or more restrictive airworthiness limitations and/or 
maintenance actions.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2017-0223R1, which is superseded, and 
requires accomplishment of the actions specified in the TLD.

    This proposed AD would require revising the existing maintenance or 
inspection program to incorporate certain maintenance instructions and 
airworthiness limitations. The unsafe condition is fatigue cracking and 
damage in principal structural elements, which could result in reduced 
structural integrity of the airplane. You may examine the MCAI in the 
AD docket on the internet at https://www.regulations.gov by searching 
for and locating Docket No. FAA-2018-1069.

Relationship Between Proposed AD and AD 2018-14-11

    This NPRM does not propose to supersede AD 2018-14-11. Rather, we 
have determined that a stand-alone AD is more appropriate to address 
the changes in the MCAI. This proposed AD would require revising the 
existing maintenance or inspection program, as applicable, to 
incorporate new or more restrictive maintenance instructions and 
airworthiness limitations. Accomplishment of the proposed actions would 
then terminate all of the requirements of AD 2018-14-11.

Related Service Information Under 1 CFR Part 51

FAA's Determination

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all the relevant information and determined the unsafe 
condition described previously is likely to exist or develop on other 
products of the same type design.

Proposed Requirements of This NPRM

    This proposed AD would require revising the existing maintenance or 
inspection program, as applicable, to incorporate new or revised 
maintenance instructions and airworthiness limitations.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections). 
Compliance with these actions is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired in 
the areas addressed by this proposed AD, the operator may not be able 
to accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must request 
approval for an alternative method of compliance according to paragraph 
(l)(1) of this proposed AD.

Difference Between This Proposed AD and the MCAI

    The MCAI specifies that if there are findings from the 
airworthiness limitations section (ALS) inspection tasks, corrective 
actions must be accomplished in accordance with Avions de Transport 
R[eacute]gional maintenance documentation. However, this proposed AD 
does not include that requirement. Operators of U.S.-registered 
airplanes are required by

[[Page 4014]]

general airworthiness and operational regulations to perform 
maintenance using methods that are acceptable to the FAA. We consider 
those methods to be adequate to address any corrective actions 
necessitated by the findings of ALS inspections required by this 
proposed AD.

Costs of Compliance

    We estimate that this proposed AD affects 23 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:
    We have determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although we recognize that this number may vary from operator to 
operator. In the past, we have estimated that this action takes 1 work-
hour per airplane. Since operators incorporate maintenance or 
inspection program changes for their affected fleet(s), we have 
determined that a per-operator estimate is more accurate than a per-
airplane estimate. Therefore, we estimate the total cost per operator 
to be $7,650 (90 work-hours x $85 per work-hour).

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.
    This proposed AD is issued in accordance with authority delegated 
by the Executive Director, Aircraft Certification Service, as 
authorized by FAA Order 8000.51C. In accordance with that order, 
issuance of ADs is normally a function of the Compliance and 
Airworthiness Division, but during this transition period, the 
Executive Director has delegated the authority to issue ADs applicable 
to transport category airplanes and associated appliances to the 
Director of the System Oversight Division.

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 above, 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; 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.
