SUPPLEMENTARY INFORMATION: Discussion The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019–0034, dated February 14, 2019 (EASA AD 2019–0034) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all Airbus Helicopters Model SA341G and SA342J helicopters. Although EASA AD 2019–0034 applies to all Model SA341G and SA342J PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 21927 helicopters, this AD applies to helicopters with an affected part installed instead. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus Helicopters Model SA341G and SA342J helicopters. The NPRM published in the Federal Register on December 28, 2020 (85 FR 84275). The NPRM was prompted by the determination that a new life limit was necessary for certain TRBs. The NPRM proposed to require replacing certain TRBs, re-identifying certain TRBs, and repairing certain other TRBs, as specified in an EASA AD. The FAA is issuing this AD to address TRBs that might break, resulting in loss of tail rotor control and consequent loss of control of the helicopter. See the MCAI for additional background information. Comments The FAA gave the public the opportunity to participate in developing this final rule. The FAA received no comments on the NPRM or on the determination of the cost to the public. Conclusion The FAA reviewed the relevant data and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. Related Service Information Under 1 CFR Part 51 EASA AD 2019–0034 describes procedures for replacing TRBs having certain part numbers, re-identifying TRBs having a certain part number and certain serial numbers, and repairing TRBs that have been reworked/repaired/ modified before being re-identified. This material 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 20 helicopters of U.S. registry. The FAA estimates the following costs to comply with this AD: E:\FR\FM\26APR1.SGM 26APR1 21928 Federal Register / Vol. 86, No. 78 / Monday, April 26, 2021 / Rules and Regulations ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 1 work-hour × $85 per hour = $85 .............................................................................................. $3,900 $3,985 $79,700 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 products 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.

No. 3954] Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: This rule amends, suspends, or removes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide for the safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

Telephone: (405) 954–4164. SUPPLEMENTARY INFORMATION: This rule amends 14 CFR part 97 by amending the referenced SIAPs. The complete regulatory description of each SIAP is listed on the appropriate FAA Form 8260, as modified by the National Flight Data Center (NFDC)/Permanent Notice to Airmen (P–NOTAM), and is incorporated by reference under 5 U.S.C. 552(a), 1 CFR part 51, and 14 CFR 97.20. The large number of SIAPs, their complex nature, and the need for a special format make their verbatim publication in the Federal Register expensive and impractical. Further, PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 21929 airmen do not use the regulatory text of the SIAPs, but refer to their graphic depiction on charts printed by publishers of aeronautical materials. Thus, the advantages of incorporation by reference are realized and publication of the complete description of each SIAP contained on FAA form documents is unnecessary. This amendment provides the affected CFR sections, and specifies the SIAPs and Takeoff Minimums and ODPs with their applicable effective dates. This amendment also identifies the airport and its location, the procedure and the amendment number. Availability and Summary of Material Incorporated by Reference The material incorporated by reference is publicly available as listed in the ADDRESSES section. The material incorporated by reference describes SIAPs, Takeoff Minimums and ODPs as identified in the amendatory language for part 97 of this final rule. The Rule This amendment to 14 CFR part 97 is effective upon publication of each separate SIAP and Takeoff Minimums and ODP as amended in the transmittal. For safety and timeliness of change considerations, this amendment incorporates only specific changes contained for each SIAP and Takeoff Minimums and ODP as modified by FDC permanent NOTAMs. The SIAPs and Takeoff Minimums and ODPs, as modified by FDC permanent NOTAM, and contained in this amendment are based on criteria contained in the U.S. Standard for Terminal Instrument Procedures (TERPS). In developing these changes to SIAPs and Takeoff Minimums and ODPs, the TERPS criteria were applied only to specific conditions existing at the affected airports. All SIAP amendments in this rule have been previously issued by the FAA in a FDC NOTAM as an emergency action of immediate flight safety relating directly to published aeronautical charts. The circumstances that created the need for these SIAP and Takeoff Minimums and ODP amendments require making them effective in less than 30 days. Because of the close and immediate relationship between these SIAPs, Takeoff Minimums and ODPs, and safety in air commerce, I find that notice and public procedure under 5 U.S.C. 553(b) are impracticable and contrary to the public interest and, where applicable, under 5 U.S.C. 553(d), good E:\FR\FM\26APR1.SGM 26APR1

SUPPLEMENTARY INFORMATION:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0034, dated February 14, 2019 
(EASA AD 2019-0034) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for all Airbus Helicopters Model SA341G and SA342J helicopters. 
Although EASA AD 2019-0034 applies to all Model SA341G and SA342J 
helicopters, this AD applies to helicopters with an affected part 
installed instead.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain Airbus 
Helicopters Model SA341G and SA342J helicopters. The NPRM published in 
the Federal Register on December 28, 2020 (85 FR 84275). The NPRM was 
prompted by the determination that a new life limit was necessary for 
certain TRBs. The NPRM proposed to require replacing certain TRBs, re-
identifying certain TRBs, and repairing certain other TRBs, as 
specified in an EASA AD.
    The FAA is issuing this AD to address TRBs that might break, 
resulting in loss of tail rotor control and consequent loss of control 
of the helicopter. See the MCAI for additional background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA received no comments on the NPRM or 
on the determination of the cost to the public.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
and the public interest require adopting this final rule as proposed, 
except for minor editorial changes. The FAA has determined that these 
minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    EASA AD 2019-0034 describes procedures for replacing TRBs having 
certain part numbers, re-identifying TRBs having a certain part number 
and certain serial numbers, and repairing TRBs that have been reworked/
repaired/modified before being re-identified.
    This material 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 20 helicopters of U.S. 
registry. The FAA estimates the following costs to comply with this 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.
    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 products 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.

helicopters, certificated in any category, equipped with any tail 
rotor blade (TRB) specified in paragraph (c)(1) or (2) of this AD.
    (1) An affected part as defined in European Union Aviation 
Safety Agency (EASA) AD 2019-0034, dated February 14, 2019 (EASA AD 
2019-0034).
    (2) A TRB having part number (P/N) 341A335101.01, P/N 
341A335130.05, or P/N 341A335130.06.

(d) Subject

    Joint Aircraft System Component (JASC) Code 6410, Tail Rotor 
Blades.

(e) Reason

    This AD was prompted by the determination that a new life limit 
was necessary for TRBs that were manufactured without a new process 
that affects the structural characteristics. The FAA is issuing this 
AD to address TRBs that might break, resulting in loss of tail rotor 
control and consequent loss of control of the helicopter.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with, EASA AD 2019-0034.

    (1) Where EASA AD 2019-0034 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) The ``Remarks'' section of EASA AD 2019-0034 does not apply 
to this AD.
    (3) Where EASA AD 2019-0034 refers to flight hours (FH), this AD 
requires using hours time-in-service.
    (4) Where paragraph (4) of EASA AD 2019-0034 specifies to 
contact the manufacturer, for this AD, repair using a method 
approved by the Manager, Strategic Policy Rotorcraft Section, FAA. 
For a repair method to be approved by the Manager, Strategic Policy 
Rotorcraft Section, as required by this paragraph, the Manager's 
approval letter must specifically refer to this AD.
    (5) Where paragraph (5) of EASA AD 2019-0034 specifies it must 
be determined that the rework/repair/modification is valid for part 
number 341A335130.06, for this AD, rework/repair/modification of an 
affected part is prohibited.

(i) Special Flight Permit

    Special flight permits, as described in 14 CFR 21.197 and 
21.199, are not allowed.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, International Validation Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19,
