In addition, section 302(b) of RCDRIA requires new regulations and amendments to regulations that impose additional reporting, disclosures, or other new requirements on insured depository institutions generally to take effect on the first day of a calendar quarter that begins on or after the date on which the regulations are published in final form.49 The amendments to the FDIC’s deposit insurance assessment regulations under this final rule do not impose additional reporting, disclosures, or other new requirements. Nonetheless, the FDIC considered the requirements of RCDRIA when finalizing this rule with an effective date of January 1, 2020. List of Subjects in 12 CFR Part 327 Bank deposit insurance, Banks, Banking, Savings associations. Authority and Issuance For the reasons set forth above, the FDIC amends part 327 of title 12 of the Code of Federal Regulations as follows: PART 327—ASSESSMENTS 1. The authority for 12 CFR part 327 continues to read as follows: ■ Authority: 12 U.S.C. 1441, 1813, 1815, 1817–19, 1821. X. Solicitation of Comments on Use of Plain Language ■ Section 722 of the Gramm-LeachBliley Act 50 requires the Federal banking agencies to use plain language in all proposed and final rules published after January 1, 2000. The FDIC has sought to present the final rule in a simple and straightforward manner and did not receive any comments on the use of plain language. § 327.8 XI. The Congressional Review Act lotter on DSKBCFDHB2PROD with RULES based enterprises in domestic and export markets.53 The OMB has determined that the final rule is not a major rule for purposes of the Congressional Review Act. The FDIC will submit the final rule and other appropriate reports to Congress and the Government Accountability Office for review. For purposes of Congressional Review Act, the OMB makes a determination as to whether a final rule constitutes a ‘‘major’’ rule.51 If a rule is deemed a ‘‘major rule’’ by the OMB, the Congressional Review Act generally provides that the rule may not take effect until at least 60 days following its publication.52 The Congressional Review Act defines a ‘‘major rule’’ as any rule that the Administrator of the Office of Information and Regulatory Affairs of the OMB finds has resulted in or is likely to result in—(A) an annual effect on the economy of $100,000,000 or more; (B) a major increase in costs or prices for consumers, individual industries, Federal, State, or local government agencies or geographic regions, or (C) significant adverse effects on competition, employment, investment, productivity, innovation, or on the ability of United States-based enterprises to compete with foreign49 12 U.S.C. 4802(b).

SUPPLEMENTARY INFORMATION: lotter on DSKBCFDHB2PROD with RULES Discussion On June 1, 2018, at 83 FR 25408, the Federal Register published the FAA’s notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 by adding an AD that would apply to BHTC Model 427 helicopters with a vertical fin part number (P/N) 427–035– 840–105 or P/N 427–035–840–109 installed. The NPRM proposed to require inspecting the inboard skin of the vertical fin around the four tailboom attachment points. The proposed requirements were intended to detect a crack on the vertical fin skin. This condition could lead to structural failure of the fin, separation of the skin from the helicopter, damage to the main or tail rotor blades and loss of helicopter control. The NPRM was prompted by Canadian AD No. CF–2017–03, dated January 31, 2017 (Transport Canada AD CF–2017–03), issued by Transport Canada, which is the aviation authority for Canada, to correct an unsafe condition for BHTC Model 427 helicopters with vertical fin P/N 427– 035–840–105 or P/N 427–035–840–109 installed. Transport Canada advises of three reports of cracked vertical fin VerDate Sep<11>2014 22:31 Dec 05, 2019 Jkt 250001 skins that resulted from metal fatigue. If not detected, the crack may grow to a critical length, causing the fin to fail, separate from the helicopter, and damage the main or tail rotor blades, leading to their in-flight failure. Loss of the fin may also adversely affect the helicopter’s directional stability, leading to loss of directional control, Transport Canada advises. Transport Canada consequently requires repetitively inspecting the vertical fins for a crack, and if a crack is detected, replacing the fin before further flight. Comments After the NPRM was published, the FAA received comments from one commenter. However, the comment addressed neither the proposed actions nor the determination of the cost to the public. Therefore, the FAA has made no changes to this AD. FAA’s Determination These helicopters have been approved by the aviation authority of Canada and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with Canada, Transport Canada, its technical representative, has notified the FAA about the unsafe condition described in the Transport Canada AD. The FAA is issuing this AD after evaluating all known relevant information and determined that an unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs and that air safety and the public interest require adopting the AD requirements as proposed. 66839 incur the following costs in order to comply with this AD. Labor costs are estimated at $85 per work-hour. • Performing the visual inspection requires about 2.25 work-hours for an estimated cost of $191 per helicopter and $5,157 for the U.S. fleet. • Replacing the fin requires about 4 work-hours, and parts cost about $10,000, for an estimated cost of $10,340 per helicopter. • Assigning a serial number to the fin takes about 0.5 work-hours for an estimated cost of $43 per helicopter. 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. The FAA is 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 helicopters identified in this rulemaking action. Related Service Information Under 1 CFR Part 51 The FAA reviewed Bell Helicopter Alert Service Bulletin 427–15–38, Revision A, dated November 14, 2016, which specifies repetitive inspections of the vertical fins every 100 hours timein-service (TIS) once the vertical fin has accumulated 1,500 hours TIS. This inspection also was incorporated in Chapter 4 of the maintenance manual. This service information also specifies serial numbers are to be assigned to vertical fins that do not have a serial number. 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. 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) Will not affect intrastate aviation in Alaska, and (3) 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. The FAA prepared an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

SUPPLEMENTARY INFORMATION:

Discussion

    On June 1, 2018, at 83 FR 25408, the Federal Register published the 
FAA's notice of proposed rulemaking (NPRM), which proposed to amend 14 
CFR part 39 by adding an AD that would apply to BHTC Model 427 
helicopters with a vertical fin part number (P/N) 427-035-840-105 or P/
N 427-035-840-109 installed. The NPRM proposed to require inspecting 
the inboard skin of the vertical fin around the four tailboom 
attachment points. The proposed requirements were intended to detect a 
crack on the vertical fin skin. This condition could lead to structural 
failure of the fin, separation of the skin from the helicopter, damage 
to the main or tail rotor blades and loss of helicopter control.
    The NPRM was prompted by Canadian AD No. CF-2017-03, dated January 
31, 2017 (Transport Canada AD CF-2017-03), issued by Transport Canada, 
which is the aviation authority for Canada, to correct an unsafe 
condition for BHTC Model 427 helicopters with vertical fin P/N 427-035-
840-105 or P/N 427-035-840-109 installed. Transport Canada advises of 
three reports of cracked vertical fin skins that resulted from metal 
fatigue. If not detected, the crack may grow to a critical length, 
causing the fin to fail, separate from the helicopter, and damage the 
main or tail rotor blades, leading to their in-flight failure. Loss of 
the fin may also adversely affect the helicopter's directional 
stability, leading to loss of directional control, Transport Canada 
advises.
    Transport Canada consequently requires repetitively inspecting the 
vertical fins for a crack, and if a crack is detected, replacing the 
fin before further flight.

Comments

    After the NPRM was published, the FAA received comments from one 
commenter. However, the comment addressed neither the proposed actions 
nor the determination of the cost to the public. Therefore, the FAA has 
made no changes to this AD.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Canada and are approved for operation in the United States. Pursuant to 
the FAA's bilateral agreement with Canada, Transport Canada, its 
technical representative, has notified the FAA about the unsafe 
condition described in the Transport Canada AD. The FAA is issuing this 
AD after evaluating all known relevant information and determined that 
an unsafe condition exists and is likely to exist or develop on other 
helicopters of these same type designs and that air safety and the 
public interest require adopting the AD requirements as proposed.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Bell Helicopter Alert Service Bulletin 427-15-38, 
Revision A, dated November 14, 2016, which specifies repetitive 
inspections of the vertical fins every 100 hours time-in-service (TIS) 
once the vertical fin has accumulated 1,500 hours TIS. This inspection 
also was incorporated in Chapter 4 of the maintenance manual. This 
service information also specifies serial numbers are to be assigned to 
vertical fins that do not have a serial number.
    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.

Costs of Compliance

    The FAA estimates that this AD affects 27 helicopters of U.S. 
Registry. The FAA estimates that operators may incur the following 
costs in order to comply with this AD. Labor costs are estimated at $85 
per work-hour.
     Performing the visual inspection requires about 2.25 work-
hours for an estimated cost of $191 per helicopter and $5,157 for the 
U.S. fleet.
     Replacing the fin requires about 4 work-hours, and parts 
cost about $10,000, for an estimated cost of $10,340 per helicopter.
     Assigning a serial number to the fin takes about 0.5 work-
hours for an estimated cost of $43 per helicopter.

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.
    The FAA is 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 helicopters identified in this rulemaking action.

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) Will not affect intrastate aviation in Alaska, and
    (3) 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.
    The FAA prepared an economic evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2019-23-09 Bell Helicopter Textron Canada Limited: Amendment 39-
19803; Docket No. FAA-2017-1105; Product Identifier 2017-SW-023-AD.

(a) Applicability

    This AD applies to Bell Helicopter Textron Canada Limited Model 
427 helicopters with a vertical fin part number (P/N) 427-035-840-
105 or P/N 427-035-840-109 installed, certificated in any category.

(b) Unsafe Condition

    This AD defines the unsafe condition as a crack on the vertical 
fin skin. This condition could lead to structural failure of the 
fin, separation of the skin from the helicopter, damage to the main 
or tail rotor blades and loss of helicopter control.

(c) Effective Date

    This AD becomes effective January 10, 2020.

(d) Compliance

    You are responsible for performing each action required by this 
AD within the specified compliance time unless it has already been 
accomplished prior to that time.

(e) Required Actions

    Within 25 hours time-in-service (TIS) or before the helicopter 
has accumulated 1,500 hours TIS, whichever occurs later, and 
thereafter at intervals not to exceed 100 hours TIS:
    (1) Remove the vertical fin and clean the vertical fin 
attachment area with a soap solution to remove all traces of dirt, 
stains, exhaust residue, and oil. Rinse the area with water and let 
dry.
    (i) Using a 10X power magnifying glass, visually inspect the 
inboard skin of the vertical fin for a crack around the four 
tailboom attachment points as depicted in Figure 1 of Bell 
Helicopter Alert Service Bulletin 427-15-38, Revision A, dated 
November 14, 2016. Pay particular attention to the upper aft 
attachment point.
    (ii) If there is a crack, replace the vertical fin before 
further flight.
    (2) If the vertical fin does not have a serial number, assign a 
serial number using the helicopter serial number, and permanently 
mark the new serial number on the vertical fin data plate. Create a 
component history card or equivalent record and annotate the serial 
number.
