Download as PDF sradovich on DSK3GMQ082PROD with PROPOSALS Federal Register / Vol. 83, No. 107 / Monday, June 4, 2018 / Proposed Rules benefit include adding a savings component, financial education, reporting of members’ payment of PALs I loans to credit bureaus, or electronic loan transactions as part of a PALs I program. In addition, although a Federal credit union cannot require members to authorize a payroll deduction, a Federal credit union should encourage or incentivize members to utilize payroll deduction. (2) Underwriting. Federal credit unions need to develop minimum underwriting standards that account for a member’s need for quickly available funds, while adhering to principles of responsible lending. Underwriting standards should address required documentation for proof of employment or income, including at least two recent paycheck stubs. Federal credit unions should be able to use a borrower’s proof of recurring income as the key criterion in developing standards for maturity lengths and loan amounts so a borrower can manage repayment of the loan. For members with established accounts, Federal credit unions should only need to review a member’s account records and proof of recurring income or employment. (3) Risk avoidance. Federal credit unions need to consider risk avoidance strategies, including: Requiring members to participate in direct deposit and conducting a thorough evaluation of the Federal credit union’s resources and ability to engage in a PALs I loan program. (iv)(A) Payday alternative loans II (PALs II). Notwithstanding the provisions in paragraph (c)(7)(ii) of this section, a Federal credit union may charge an interest rate of 1000 basis points above the maximum interest rate as established by the Board, provided the Federal credit union is making a closed-end loan in accordance with the following conditions: (1) The principal of the loan is not more than $2,000; (2) The loan has a minimum maturity term of one month and a maximum maturity term of twelve months; (3) The Federal credit union does not make more than one PALs loan at a time to a borrower; (4) The Federal credit union must not roll-over any PALs II loan; (i) The prohibition against roll-overs does not apply to an extension of the loan term within the maximum loan terms in paragraph (c)(7)(iv)(2)(j)(1)(ii) provided the Federal credit union does not charge any additional fees or extend any new credit. (ii) [Reserved] (5) The Federal credit union fully amortizes the loan; VerDate Sep<11>2014 16:57 Jun 01, 2018 Jkt 244001 (6) The Federal credit union charges an application fee to all members applying for a new loan that reflects the actual costs associated with processing the application, but in no case may the application fee exceed $20; and (7) The Federal credit union includes, in its written lending policies, a limit on the aggregate dollar amount of PALs I and PALs II loans made under this section of a maximum of 20% of net worth and implements appropriate underwriting guidelines to minimize risk; for example, requiring a borrower to verify employment by producing at least two recent pay stubs. (B) PALs II Loan Program guidance and best practices. The PALs II loan program guidance and best practices are the same as those outlined for PALs I in paragraph (c)(7)(iii)(B) of this section.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2017–0181, dated September 18, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus Defense and Space S.A. Model CN–235, CN–235–100, CN–235– 200, CN–235–300, and C–295 airplanes The MCAI states: Cracks were reportedly found on nose landing gear (NLG) door actuator shaft assemblies on CN–235 aeroplanes. The subsequent design review determined that combined or multiple rupture of the affected shaft assembly could occur, without this being signalised to the flight crew. This condition, if not detected and corrected, could lead to an in-flight NLG door opening, possibly resulting in detachment of the affected door, with consequent damage to, or reduced control of, the aeroplane and injury to persons on the ground. To address this unsafe condition, Airbus Defence & Space (D&S) issued Alert Operators Transmissions AOT–CN235–32– 0001 Revision (Rev.) 2 and AOT–C295–32– 0001 Rev. 2 to provide inspection instructions. For the reasons described above, this [EASA] AD requires repetitive detailed (DET) or special detailed [rototest] inspections of the NLG door actuator shaft assembly, as applicable, and, depending on findings, corrective actions [including replacement of any cracked component, or cracked NLG door mechanism actuator shaft assembly with a serviceable part]. This [EASA] AD also introduces a modification for CN–235 aeroplanes as (optional) terminating action for the repetitive inspections as required by this [EASA] AD. 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– 0493. Related Service Information Under 1 CFR Part 51 Airbus Defence and Space has issued Alert Operators Transmission (AOT) AOT–CN235–32–0001, Revision 2, dated October 26, 2016; and AOT AOT– C295–32–0001, Revision 2, dated October 26, 2016. This service information describes procedures for inspections for cracking of the door mechanism actuator shaft assemblies of the NLG, and corrective actions. These documents are distinct since they apply to different airplane models. Airbus Defence and Space has also issued Service Bulletin 235–32–0031C, dated September 22, 2016. This service information describes procedures for modification of the NLG door latching mechanism. 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 these same type designs. Costs of Compliance We estimate that this proposed AD affects 14 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Inspections .................... 21 work-hours × $85 per hour = $1,785 per inspection cycle. $0 ................. Cost per product Cost on U.S. operators $1,785 per inspection cycle. $24,990 per inspection cycle. OPTIONAL TERMINATING ACTION Action Labor cost Modification for Model CN–235 airplanes. 10 work-hours × $85 per hour = $850 ...................................................... We estimate the following costs to do any necessary replacements that would Parts cost be required based on the results of the proposed inspections. We have no way $33,626 Cost per product $34,476 of determining the number of aircraft that might need these replacements: ON-CONDITION COSTS sradovich on DSK3GMQ082PROD with PROPOSALS Action Labor cost Replacement .................................... 14 work-hours × $85 per hour = $1,190 ................................................... 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 VerDate Sep<11>2014 16:57 Jun 01, 2018 Jkt 244001 Parts cost the FAA Administrator. ‘‘Subtitle VII: Aviation Programs,’’ describes in more detail the scope of the Agency’s authority. PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 $18,720 Cost per product $19,910 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 E:\FR\FM\04JNP1.SGM 04JNP1 25589 Federal Register / Vol. 83, No. 107 / Monday, June 4, 2018 / Proposed Rules 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 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.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Airbus Defense and Space S.A. Model CN-235, CN-235-100, CN-235-200, CN-
235-300, and C-295 airplanes. This proposed AD was prompted by reports 
that cracks were found on the door mechanism actuator shaft assemblies 
of the nose landing gear (NLG). This proposed AD would require 
repetitive inspections of the NLG door mechanism actuator shaft 
assemblies having certain part numbers, and corrective actions if 
necessary. This proposed AD would also provide an optional terminating 
action for the repetitive inspections for Model CN-235, CN-235-100, CN-
235-200, and CN-235-300 airplanes. We are proposing this AD to address 
the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by July 19, 2018.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0181, dated September 18, 2017 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus Defense and Space S.A. Model 
CN-235, CN-235-100, CN-235-200, CN-235-300, and C-295 airplanes The 
MCAI states:

    Cracks were reportedly found on nose landing gear (NLG) door 
actuator shaft assemblies on CN-235 aeroplanes. The subsequent 
design review determined that combined or multiple rupture of the 
affected shaft assembly could occur, without this being signalised 
to the flight crew.
    This condition, if not detected and corrected, could lead to an 
in-flight NLG door opening, possibly resulting in detachment of the 
affected door, with consequent damage to, or reduced control of, the 
aeroplane and injury to persons on the ground.
    To address this unsafe condition, Airbus Defence & Space (D&S) 
issued Alert Operators Transmissions AOT-CN235-32-0001 Revision 
(Rev.) 2 and AOT-C295-32-0001 Rev. 2 to provide inspection 
instructions.
    For the reasons described above, this [EASA] AD requires 
repetitive detailed (DET) or special detailed [rototest] inspections 
of the NLG door actuator shaft assembly, as applicable, and, 
depending on findings, corrective actions [including replacement of 
any cracked component, or cracked NLG door mechanism actuator shaft 
assembly with a serviceable part]. This [EASA] AD also introduces a 
modification for CN-235 aeroplanes as (optional) terminating action 
for the repetitive inspections as required by this [EASA] AD.

    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-
0493.

Related Service Information Under 1 CFR Part 51

    Airbus Defence and Space has issued Alert Operators Transmission 
(AOT) AOT-CN235-32-0001, Revision 2, dated October 26, 2016; and AOT 
AOT-C295-32-0001, Revision 2, dated October 26, 2016. This service 
information describes procedures for inspections for cracking of the 
door mechanism actuator shaft assemblies of the NLG, and corrective 
actions. These documents are distinct since they apply to different 
airplane models.
    Airbus Defence and Space has also issued Service Bulletin 235-32-
0031C, dated September 22, 2016. This service information describes 
procedures for modification of the NLG door latching mechanism.
    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 these 
same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 14 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

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

[[Page 25589]]

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 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.

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:
