Download as PDF 12508 Federal Register / Vol. 83, No. 56 / Thursday, March 22, 2018 / Proposed Rules daltland on DSKBBV9HB2PROD with PROPOSALS business applicants for the Business Loan Programs. See, 13 CFR 123.300(b). Although the temporary statutory alternative size standard established by the Jobs Act does not apply to the EIDL Program, SBA is considering applying the new permanent alternative size standard established for the Business Loan Programs to the EIDL Program as an alternative to industry based size standards. Request for Comments Against the above backdrop, in this ANPRM, SBA seeks comment on the following issues. 1. SBA seeks comment on whether or not the level of the temporary statutory alternative size standard under the Interim Rule (i.e., $15 million in tangible net worth and $5 million in average net income) is appropriate under the current credit environment and as a new permanent alternative size standard. Commenters in support of the level in the Interim Rule should provide justification, along with supporting data and analysis to support their position. Similarly, commenters who believe the level established in the Interim Rule is not appropriate as a permanent alternative size standard should suggest, along with supporting data and analysis, a different alternative size standard which they believe would be more appropriate. The suggested alternative size standard must be based on tangible net worth and average net income as required by section 3(a)(5) of the Small Business Act. 15 U.S.C. 632(a)(5). 2. SBA seeks comment on the impact of using an alternative size standard on small businesses seeking loans through its Business Loan Programs. Specifically, SBA welcomes information on industries/sectors where small businesses benefit the most or do not benefit at all from the use of an alternative size standard. Similarly, SBA is also looking for data on the number of businesses approved for SBA’s Business Loans under the temporary statutory alternative size standard that otherwise could not have been approved under their industry based size standards. 3. SBA invites suggestions on sources of relevant data and information, especially tangible net worth and average net income of applicants to SBA’s Business Loan Programs, that SBA can evaluate to assess the impact of the Interim Rule on small businesses and use in developing a new permanent alternative size standard and in estimating the impact of the new permanent alternative size standard. 4. SBA invites comments from interested parties on the proposal to VerDate Sep<11>2014 18:44 Mar 21, 2018 Jkt 244001 apply the same new permanent alternative size standard established for the Business Loan Programs to the EIDL Program as an alternative to industry based size standards. 5. SBA also seeks comment on how the Interim Rule has affected the processes used by lenders participating in the Business Loan Programs and what effects a permanent alternative size standard would have on application processes and processing times. 6. SBA invites comment on the effects of the Interim Rule on conventional small business lending. Specifically, SBA welcomes input on whether, and to what extent, if any, SBA Business Loans approved under the Interim Rule have substituted for or displaced directly or indirectly conventional small business lending, or whether such SBA Business Loans played more of a supplementary role in conventional small business lending activity.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2017– 0223R1, dated December 15, 2017 (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 Regional 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 ATR72–101/–201/–102/– 202/–211/–212/–212A Time Limits (TL) document. These instructions have been identified as mandatory actions for continued airworthiness. Failure to accomplish these instructions could result in an unsafe condition. Consequently, ATR published Revision 15 of the ATR72–101/–201/–102/–202/–211/– 212/–212A TL document, which contains new and/or more restrictive CMRs and airworthiness limitation tasks. For the reasons described above, this [EASA] AD requires accomplishment of the actions specified in the ATR72–101/–201/– 102/–202/–211/–212/–212A TL document Revision 15, hereafter referred to as ‘the TLD’ in this [EASA] AD. This [EASA] AD, in conjunction with two other [EASA] ADs related to ATR42–200/– 300/–320 (EASA AD 2017–0221) and ATR42–400/–500 (EASA AD 2017–0222) aeroplanes, retains the requirements of EASA AD 2009–0241 and EASA AD 2012–0193. Once all these three ADs are effective, EASA will cancel EASA AD 2009–0242 and EASA AD 2012–0193. This [EASA] AD is revised to provide the correct issue date (02 May 2017) of the TLD. The original [EASA] AD inadvertently referenced the EASA approval date for that document. This NPRM would require revising the maintenance or inspection program to incorporate certain maintenance instructions and airworthiness limitations. The unsafe condition is fatigue cracking, damage, and corrosion 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– 0166. Related Service Information Under 1 CFR Part 51 ATR–GIE Avions de Transport ´ Regional has issued the ATR72 Time Limits document, Revision 15, dated May 2, 2017. The 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 and Requirements of This Proposed AD 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 pertinent information and determined an unsafe condition exists and is likely to exist or 12509 develop on other products of the same type design. This AD requires 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 (k)(1) of this proposed AD. The request should include a description of changes to the required actions that will ensure the continued damage tolerance of the affected structure. Similar to the MCAI, this proposed AD would not supersede AD 2000–23– 26, Amendment 39–11999 (65 FR 70775, November 28, 2000) (‘‘AD 2000– 23–26’’), or AD 2008–04–19 R1, Amendment 39–16069 (74 FR 56713, November 3, 2009) (‘‘AD 2008–04–19 R1’’). Rather, we have determined that a stand-alone AD would be more appropriate to address the changes in the MCAI. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate maintenance requirements and/or airworthiness limitations that are new or more restrictive than those required by AD 2000–23–26 and AD 2008–04–19 R1. Accomplishment of the proposed actions would then terminate all the requirements of AD 2000–23–26 and AD 2008–04–19 R1. Costs of Compliance We estimate that this proposed AD affects 26 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Labor cost 1 Parts cost 90 work-hours × $85 per hour = $7,650 ........ None .............. Action Maintenance or inspection program revision Cost per product $7,650 Cost on U.S. operators $198,900 1 In daltland on DSKBBV9HB2PROD with PROPOSALS the past, we have used 1 work-hour for revisions of the maintenance or inspection program. We have determined that incorporating the entire airworthiness limitation document specified in this proposed AD would take significantly longer than 1 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 VerDate Sep<11>2014 18:44 Mar 21, 2018 Jkt 244001 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 PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 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. E:\FR\FM\22MRP1.SGM 22MRP1 Federal Register / Vol. 83, No. 56 / Thursday, March 22, 2018 / Proposed Rules 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 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. daltland on DSKBBV9HB2PROD with PROPOSALS List of Subjects in 14 CFR Part 39 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 
2017-0223R1, dated December 15, 2017 (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 ATR72-101/-201/-102/-202/
-211/-212/-212A Time Limits (TL) document. These instructions have 
been identified as mandatory actions for continued airworthiness.
    Failure to accomplish these instructions could result in an 
unsafe condition.
    Consequently, ATR published Revision 15 of the ATR72-101/-201/-
102/-202/-211/-212/-212A TL document, which contains new and/or more 
restrictive CMRs and airworthiness limitation tasks.
    For the reasons described above, this [EASA] AD requires 
accomplishment of the actions specified in the ATR72-101/-201/-102/-
202/-211/-212/-212A TL document Revision 15, hereafter referred to 
as `the TLD' in this [EASA] AD.
    This [EASA] AD, in conjunction with two other [EASA] ADs related 
to ATR42-200/-300/-320 (EASA AD 2017-0221) and ATR42-400/-500 (EASA 
AD 2017-0222) aeroplanes, retains the requirements of EASA AD 2009-
0241 and EASA AD 2012-0193. Once all these three ADs are effective, 
EASA will cancel EASA AD 2009-0242 and EASA AD 2012-0193.
    This [EASA] AD is revised to provide the correct issue date (02 
May 2017) of the TLD. The original [EASA] AD inadvertently 
referenced the EASA approval date for that document.

    This NPRM would require revising the maintenance or inspection 
program to incorporate certain maintenance instructions and 
airworthiness limitations. The unsafe condition is fatigue cracking, 
damage, and corrosion 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-2018-0166.

Related Service Information Under 1 CFR Part 51

    ATR-GIE Avions de Transport R[eacute]gional has issued the ATR72 
Time Limits document, Revision 15, dated May 2, 2017. The 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 and Requirements of This Proposed AD

    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 pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.
    This AD requires 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 (k)(1) of this proposed AD. 
The request should include a description of changes to the required 
actions that will ensure the continued damage tolerance of the affected 
structure.
    Similar to the MCAI, this proposed AD would not supersede AD 2000-
23-26, Amendment 39-11999 (65 FR 70775, November 28, 2000) (``AD 2000-
23-26''), or AD 2008-04-19 R1, Amendment 39-16069 (74 FR 56713, 
November 3, 2009) (``AD 2008-04-19 R1''). Rather, we have determined 
that a stand-alone AD would be more appropriate to address the changes 
in the MCAI. This proposed AD would require revising the maintenance or 
inspection program, as applicable, to incorporate maintenance 
requirements and/or airworthiness limitations that are new or more 
restrictive than those required by AD 2000-23-26 and AD 2008-04-19 R1. 
Accomplishment of the proposed actions would then terminate all the 
requirements of AD 2000-23-26 and AD 2008-04-19 R1.

Costs of Compliance

    We estimate that this proposed AD affects 26 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
              Action                  Labor cost \1\            Parts cost            product        operators

Maintenance or inspection program  90 work-hours x $85   None...................          $7,650        $198,900
 revision.                          per hour = $7,650.
----------------------------------------------------------------------------------------------------------------
\1\ In the past, we have used 1 work-hour for revisions of the maintenance or inspection program. We have
  determined that incorporating the entire airworthiness limitation document specified in this proposed AD would
  take significantly longer than 1 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.

[[Page 12510]]

    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 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.
