SUPPLEMENTARY INFORMATION: Background The Board’s PSR policy establishes the procedures for measuring balances intraday in institutions’ accounts at the Reserve Banks by setting forth the times at which credits and debits for various types of transactions are posted to those accounts (‘‘the posting rules’’).1 The application of these posting rules determines an institution’s intraday account balance and whether it has incurred a negative balance (daylight overdraft). On September 23, 2015, the Board approved enhancements to the Reserve Banks’ FedACH® SameDay Service (FedACH SameDay Service) in light of amendments to NACHA—The Electronic Payments Association’s Operating Rules and Guidelines.2 The NACHA amendments, as incorporated into Operating Circular 4, become effective in three phases, beginning with same-day credits in September 2016, same-day debits in September 2017, and faster funds availability in March 2018. Next-day settlement remains available. The Board is revising the PSR policy’s posting rules for same-day ACH transactions to conform to amendments to 31 CFR part 210 (part 210) announced on September 11, 2017 by Fiscal Service.3 Specifically, the amended posting rules conform to the decision of the Fiscal Service to allow Federal agencies to originate and receive sameday entries beginning September 15, 2017.4 Policy on Payment System Risk asabaliauskas on DSKBBXCHB2PROD with RULES The Federal Reserve Policy on Payment System Risk, section II.A, under the heading ‘‘Procedures for Measuring Daylight Overdrafts’’ and the 1 The Board’s PSR policy is available at https:// www.federalreserve.gov/paymentsystems/files/psr_ policy.pdf. 2 80 FR 58248 (Sep. 28, 2015). NACHA, whose membership consists of insured financial institutions and regional payment associations, establishes network-wide ACH rules through its Operating Rules and Guidelines. As an ACH operator, the Reserve Banks, through Operating Circular 4, incorporate NACHA’s Operating Rules and Guidelines as rules that govern clearing and settlement of commercial ACH items by the Reserve Banks, except for those provisions specifically excluded in the Operating Circular. 3 The Fiscal Service amended part 210 to address changes to the NACHA Operating Rules, including NACHA’s same-day amendments. See 82 FR 42597 (Sep. 11, 2017). Part 210 governs the use of ACH by Federal agencies and incorporates the NACHA Operating Rules, with certain exceptions. 4 31 CFR 210.2(d)(7) (as amended Sept. 11, 2017).

If the Federal Reserve receives commercial ACH credit transactions from institutions monitored in real time after the scheduled close of the Fedwire Funds Service, these transactions will be processed at 12:30 a.m. the next business day, or by the ACH deposit deadline, whichever is earlier. The Account Balance Monitoring System provides intraday account information to the Reserve Banks and institutions and is used primarily to give authorized Reserve Bank personnel a mechanism to control and monitor account activity for selected institutions. For more information on ACH transaction processing, refer to the ACH Settlement Day Finality Guide available through the Federal Reserve Financial Services Web site at http:// www.frbservices.org. 6 For the three commercial check transaction posting times, the Reserve Banks will post credits and debits to institutions’ accounts for checks deposited and presented, respectively, at least 30 minutes before the posting time. 7 The Reserve Banks will identify and notify institutions with Treasury-authorized penalties on Thursdays. In the event that Thursday is a holiday, the Reserve Banks will identify and notify institutions with Treasury-authorized penalties on the following business day. Penalties will then be posted on the business day following notification. 8 With the exception of paper returns and paper notifications of change (NOCs) of prior-dated items that only post at 5:00 p.m.; paper returns of sameday forward items that only post at 5:30 p.m.; and FedLine Web returns and FedLine Web NOCs that only post at 8:30 a.m. and 5:00 p.m., depending on when the item is received by Reserve Banks.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all GE CF34–8E model turbofan engines. The NPRM published in the Federal Register on June 8, 2017 (82 FR 26615). The NPRM was prompted by a report that using a certain repair procedure for the fan OGV frame could alter the strength capability of the fan OGV frame because the repair procedure included an improper heat cycle. The NPRM proposed to require replacement of all fan OGV frames repaired using this procedure. This condition, if not corrected, could result in failure of the fan OGV frame, engine separation, and loss of the airplane. Comments We gave the public the opportunity to participate in developing this final rule. The following presents the comments received on the NPRM and the FAA’s response to each comment. Support for the NPRM The Air Line Pilots Association supports the NPRM. Request To Change Applicability Horizon Air requested we include a list of fan OGV frame affected serial numbers (S/Ns) in this AD. J-Air requested that this AD include GE Service Bulletin (SB) CF34–8E–AL S/B 72–0183, Revision 3, dated March 7, 2017, for a list of affected OGV frame S/Ns known to GE. Further, the two commenters explained that operators are not necessarily aware of which repairs have been performed. The changes were requested to take the burden off the operator to determine AD applicability. We partially agree. We disagree that SB CF34–8E–AL S/B 72–0183 provides a list of all affected OGV frame S/Ns. The list of known affected part S/Ns is based on the best available data, but is not comprehensive. It may be possible that some OGV frames were repaired, but are not known to GE and are not included in GE SB CF34–8E–AL S/B 72–0183. Operators are responsible for checking engine records to determine AD applicability. We agree to unburden operators to the maximum extent possible. In the interest of aiding operators to determine affected part S/Ns, we included GE SB CF34–8E–AL S/B 72–0183 in the Related Service Information section in the preamble of this final rule, with a note that GE SB CF34–8E–AL S/B 72– 0183 does not include a comprehensive list of all affected parts.

Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule with the change described previously. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that these changes will not increase the economic burden on any operator or increase the scope of this final rule. Related Service Information We reviewed GE CF34–8E Engine Manual, GEK 112031, 72–00–23, REPAIR 006. The repair describes procedures for applying a dry-film lubricant to the fan OGV frame with heat curing. We also reviewed GE SB CF34–8E–AL S/B 72–0183, Revision 3, dated March 7, 2017. The SB provides instructions to replace the fan OGV frames repaired as specified in GE CF34–8E Engine Manual, GEK 112031, 72–00–23, REPAIR 006. However, the SB does not provide a comprehensive list of affected parts. The SB provides a list of OGV frame S/Ns known to GE that have been repaired to GEK 112031 72–00–23 REPAIR 006.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to all GE CF34-8E model 
turbofan engines. The NPRM published in the Federal Register on June 8, 
2017 (82 FR 26615). The NPRM was prompted by a report that using a 
certain repair procedure for the fan OGV frame could alter the strength 
capability of the fan OGV frame because the repair procedure included 
an improper heat cycle. The NPRM proposed to require replacement of all 
fan OGV frames repaired using this procedure. This condition, if not 
corrected, could result in failure of the fan OGV frame, engine 
separation, and loss of the airplane.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. The following presents the comments received on the 
NPRM and the FAA's response to each comment.

Support for the NPRM

    The Air Line Pilots Association supports the NPRM.

Request To Change Applicability

    Horizon Air requested we include a list of fan OGV frame affected 
serial numbers (S/Ns) in this AD. J-Air requested that this AD include 
GE Service Bulletin (SB) CF34-8E-AL S/B 72-0183, Revision 3, dated 
March 7, 2017, for a list of affected OGV frame S/Ns known to GE. 
Further, the two commenters explained that operators are not 
necessarily aware of which repairs have been performed. The changes 
were requested to take the burden off the operator to determine AD 
applicability.
    We partially agree. We disagree that SB CF34-8E-AL S/B 72-0183 
provides a list of all affected OGV frame S/Ns. The list of known 
affected part S/Ns is based on the best available data, but is not 
comprehensive. It may be possible that some OGV frames were repaired, 
but are not known to GE and are not included in GE SB CF34-8E-AL S/B 
72-0183. Operators are responsible for checking engine records to 
determine AD applicability.
    We agree to unburden operators to the maximum extent possible. In 
the interest of aiding operators to determine affected part S/Ns, we 
included GE SB CF34-8E-AL S/B 72-0183 in the Related Service 
Information section in the preamble of this final rule, with a note 
that GE SB CF34-8E-AL S/B 72-0183 does not include a comprehensive list 
of all affected parts. GE SB CF34-8E-AL S/B 72-0183 includes a list of 
OGV frame S/Ns known to GE that have been repaired to GEK 112031 72-00-
23, REPAIR 006.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this final rule with the change described previously. We have 
determined that these minor changes:
     [Agr]re consistent with the intent that was proposed in 
the NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this final 
rule.

Related Service Information

    We reviewed GE CF34-8E Engine Manual, GEK 112031, 72-00-23, REPAIR 
006. The repair describes procedures for applying a dry-film lubricant 
to the fan OGV frame with heat curing.
    We also reviewed GE SB CF34-8E-AL S/B 72-0183, Revision 3, dated 
March 7, 2017. The SB provides instructions to replace the fan OGV 
frames repaired as specified in GE CF34-8E Engine Manual, GEK 112031, 
72-00-23, REPAIR 006. However, the SB does not provide a comprehensive 
list of affected parts. The SB provides a list of OGV frame S/Ns known 
to GE that have been repaired to GEK 112031 72-00-23 REPAIR 006.

Costs of Compliance

    We estimate that this AD affects 42 engines installed on airplanes 
of U.S. registry.
    We estimate the following costs to comply with this AD:

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue

[[Page 46671]]

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 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 engines, propellers, and 
associated appliances to the Manager, Engine and Propeller Standards 
Branch, Policy and Innovation Division.

Regulatory Findings

    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 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.
