SUPPLEMENTARY INFORMATION: PO 00000 Frm 00021 Fmt 4700 Sfmt 4700 14241 Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2017–26–10, Amendment 39–19141 (82 FR 61675, December 29, 2017) (AD 2017–26–10). AD 2017–26–10 applied to certain The Boeing Company Model 757 airplanes. The NPRM published in the Federal Register on October 13, 2020 (85 FR 64419). The NPRM was prompted by reports of unwanted lateral oscillations during landing operations, and the development of wiring changes for certain SCMs, which will improve the lateral handling qualities of the airplane during approach and landing. The NPRM proposed to require repetitive operational tests of the spoiler inhibit function. For certain airplanes, the NPRM proposed to require installing a new relay bracket assembly, making changes to the wire bundles for certain SCMs, installing new SCMs, measuring the clearance between a wire bundle and the top of the new relay bracket assembly, and applicable on-condition actions. For a certain other airplane, the NPRM proposed to require changing certain wire bundles. The FAA is issuing this AD to address unwanted lateral oscillations during landing operations, which could cause overcontrol of the airplane and subsequent lateral pilot induced oscillation, which could affect continued safe flight and landing. Comments The FAA gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA’s response to each comment. Support for the NPRM An anonymous commenter, FedEx Express, and United Airlines (UAL) stated their support for the NPRM. An additional comment from UAL is addressed below. Effect of Winglets on Accomplishment of the Proposed Actions Aviation Partners Boeing stated that the installation of winglets per Supplemental Type Certificate (STC) ST01518SE does not affect the accomplishment of the proposed actions. The FAA agrees with the commenter that STC ST01518SE does not affect the ability to accomplish the actions required by this AD. The FAA has not changed this AD in this regard. E:\FR\FM\15MRR1.SGM 15MRR1 14242 Federal Register / Vol. 86, No. 48 / Monday, March 15, 2021 / Rules and Regulations Request To Revise Certain Language in the NPRM Boeing requested that the FAA revise certain language in the NPRM. Boeing stated that in the Discussion section of the NPRM, it suggested to revise the last sentence as follows: ‘‘The FAA issued AD 2017–26–10 to address a failure condition that can cause uncommanded spoiler movement resulting in loss of controllability of the airplane.’’ Boeing commented that the change is justified based on the original safety determination of Continued Operational Safety Program (COSP) 2017–0373. Boeing also stated that in the Actions Since AD 2017–26–10 Was Issued section of the NPRM, it suggested that the FAA add the following sentence: ‘‘This change provides the equivalent lateral handling quality improvements during approach and landing as AD 2015–08–01, but with a new design implementation.’’ Boeing commented that the change is justified based on the mitigating design for COSP 2018–0094. The FAA acknowledges the commenter’s request and agrees the proposed wording provides clarity and more closely aligns with the COSP recommendations. However those sections are not carried over into this final rule. The FAA has not changed this AD in this regard. Request To Use Later Revisions of the Service Information UAL requested that the proposed AD be revised to allow for the use of later revisions of the service information in either paragraph (g) of the proposed AD (Required Actions) or in paragraph (h) of the proposed AD (Exceptions to Service Information Specifications). The FAA disagrees with the commenter’s request. The FAA may not in an AD refer to any document that does not yet exist. In general terms, the FAA is required by Office of the Federal Register (OFR) regulations for approval of materials incorporated by reference, as specified in 1 CFR 51.1(f), to either publish the service document contents as part of the actual AD language; or submit the service document to the OFR for approval as referenced material, in which case the FAA may only refer to such material in the text of an AD. The AD may refer to the service document only if the OFR approved it for incorporation by reference. See 1 CFR part 51. To allow operators to use later revisions of the referenced document (issued after publication of the AD), either the FAA must revise the AD to reference specific later revisions, or operators must request approval to use later revisions as an alternative method of compliance with this AD under the provisions of paragraph (j) of this AD. Clarification of Steps in the Service Information Boeing contacted the FAA and stated that there is an error in Boeing Alert Requirements Bulletin 757–27A0158 RB, dated July 9, 2020, and that the service information would be revised. Boeing stated that the reason for the service information revision is that step 2 in the figure 4 table incorrectly states to drill six holes, while the graphic in figure 4 accurately shows to only drill two holes. The FAA has added paragraph (h)(2) of this AD to state, ‘‘Where Boeing Alert Requirements Bulletin 757–27A0158 RB, dated July 9, 2020, specifies in figure 4 (sheet 3 of 3), step 2, to drill a quantity of six holes, this AD requires drilling two holes.’’ The FAA has also moved the content of paragraph (h) of the proposed AD to paragraph (h)(1) of this AD. Conclusion The FAA reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD with the changes described previously, and 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. The FAA also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Related Service Information Under 1 CFR Part 51 The FAA reviewed Boeing Alert Requirements Bulletin 757–27A0158 RB, dated July 9, 2020. This service information describes procedures for installing a new relay bracket assembly, making changes to the wire bundles for the SCMs, installing new SCMs, measuring the clearance between a wire bundle and the top of new relay bracket assembly, changing certain wire bundles, repetitive operational tests of the spoiler inhibit function, and applicable on-condition actions. Oncondition actions include installing a new protective sleeve, heat shrinkable to the wire bundle, doing a landing configurations warning module landing flap tests, and doing a system test for the SCMs. 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 626 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost 105 work-hours × $85 per hour = $8,925. 9 work-hours × $85 per hour = $765. 5 work-hours × $85 per hour = $425 per test cycle.

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 The FAA has determined that 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. khammond on DSKJM1Z7X2PROD with RULES List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

[Document Number NASA–21–005: Docket Number NASA–2021–001] Federal Civil Monetary Penalties Inflation Adjustment for 2021 National Aeronautics and Space Administration. ACTION: Final rule. AGENCY: The National Aeronautics and Space Administration (NASA) has adopted a final rule making inflation adjustments to civil monetary penalties within its jurisdiction. This final rule represents the annual 2021 inflation adjustments of monetary penalties. These adjustments are required by the Federal Civil Penalties Inflation Adjustment Act Improvements Act of 2015. SUMMARY: This final rule is effective March 15, 2021. FOR FURTHER INFORMATION CONTACT: Bryan R. Diederich, Office of the General Counsel, NASA Headquarters, telephone (202) 358–0216. DATES: SUPPLEMENTARY INFORMATION: I. Background The Inflation Adjustment Act, as amended by the 2015 Act, required Federal agencies to adjust the civil penalty amounts within their jurisdiction for inflation by July 1, 2016. Subsequent to the 2016 adjustment, Federal agencies were required to make an annual inflation adjustment by January 15 every year thereafter.1 Under the amended Act, any increase in a civil penalty made under the Act will apply to penalties assessed after the increase takes effect, including penalties whose associated violation predated the increase.2 The inflation adjustments mandated by the Act serve to maintain the deterrent effect of civil penalties and to promote compliance with the law. Pursuant to the Act, adjustments to the civil penalties are required to be made by January 15 of each year. The annual adjustments are based on the percent change between the U.S. Department of Labor’s Consumer Price Index for All Urban Consumers (‘‘CPI– U’’) for the month of October preceding the date of the adjustment and the CPI– U for October of the prior year (28 U.S.C. 2461 note, section (5)(b)(1)). Based on that formula, the cost-of-living adjustment multiplier for 2020 is 1.01182. Pursuant to the 2015 Act, adjustments are rounded to the nearest dollar. II. The Final Rule This final rule makes the required adjustments to civil penalties for 2021. Applying the 2021 multiplier above, the adjustments for each penalty are summarized below.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2017-26-
10, which applied to certain The Boeing Company Model 757 airplanes. AD 
2017-26-10 required deactivating the spoiler control module (SCM) 
relays and capping and stowing the associated wiring on certain 
airplanes. This AD requires repetitive operational tests of the spoiler 
inhibit function. For certain airplanes, this AD requires installing a 
new relay bracket assembly, making changes to the wire bundles for 
certain SCMs, installing new SCMs, measuring the clearance between a 
wire bundle and the top of the new relay bracket assembly, and 
applicable on-condition actions. For a certain other airplane, this AD 
requires changing certain wire bundles. This AD was prompted by reports 
of unwanted lateral oscillations during landing operations, and the 
development of wiring changes for certain SCMs, which will improve the 
lateral handling qualities of the airplane during approach and landing. 
The FAA is issuing this AD to address the unsafe condition on these 
products.

DATES: This AD is effective April 19, 2021.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 19, 
2021.

certain The Boeing Company Model 757 airplanes. The NPRM published in 
the Federal Register on October 13, 2020 (85 FR 64419). The NPRM was 
prompted by reports of unwanted lateral oscillations during landing 
operations, and the development of wiring changes for certain SCMs, 
which will improve the lateral handling qualities of the airplane 
during approach and landing. The NPRM proposed to require repetitive 
operational tests of the spoiler inhibit function. For certain 
airplanes, the NPRM proposed to require installing a new relay bracket 
assembly, making changes to the wire bundles for certain SCMs, 
installing new SCMs, measuring the clearance between a wire bundle and 
the top of the new relay bracket assembly, and applicable on-condition 
actions. For a certain other airplane, the NPRM proposed to require 
changing certain wire bundles. The FAA is issuing this AD to address 
unwanted lateral oscillations during landing operations, which could 
cause over-control of the airplane and subsequent lateral pilot induced 
oscillation, which could affect continued safe flight and landing.

Comments

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

Support for the NPRM

    An anonymous commenter, FedEx Express, and United Airlines (UAL) 
stated their support for the NPRM. An additional comment from UAL is 
addressed below.

Effect of Winglets on Accomplishment of the Proposed Actions

    Aviation Partners Boeing stated that the installation of winglets 
per Supplemental Type Certificate (STC) ST01518SE does not affect the 
accomplishment of the proposed actions.
    The FAA agrees with the commenter that STC ST01518SE does not 
affect the ability to accomplish the actions required by this AD. The 
FAA has not changed this AD in this regard.

[[Page 14242]]

Request To Revise Certain Language in the NPRM

    Boeing requested that the FAA revise certain language in the NPRM. 
Boeing stated that in the Discussion section of the NPRM, it suggested 
to revise the last sentence as follows: ``The FAA issued AD 2017-26-10 
to address a failure condition that can cause uncommanded spoiler 
movement resulting in loss of controllability of the airplane.'' Boeing 
commented that the change is justified based on the original safety 
determination of Continued Operational Safety Program (COSP) 2017-0373.
    Boeing also stated that in the Actions Since AD 2017-26-10 Was 
Issued section of the NPRM, it suggested that the FAA add the following 
sentence: ``This change provides the equivalent lateral handling 
quality improvements during approach and landing as AD 2015-08-01, but 
with a new design implementation.'' Boeing commented that the change is 
justified based on the mitigating design for COSP 2018-0094.
    The FAA acknowledges the commenter's request and agrees the 
proposed wording provides clarity and more closely aligns with the COSP 
recommendations. However those sections are not carried over into this 
final rule. The FAA has not changed this AD in this regard.

Request To Use Later Revisions of the Service Information

    UAL requested that the proposed AD be revised to allow for the use 
of later revisions of the service information in either paragraph (g) 
of the proposed AD (Required Actions) or in paragraph (h) of the 
proposed AD (Exceptions to Service Information Specifications).
    The FAA disagrees with the commenter's request. The FAA may not in 
an AD refer to any document that does not yet exist. In general terms, 
the FAA is required by Office of the Federal Register (OFR) regulations 
for approval of materials incorporated by reference, as specified in 1 
CFR 51.1(f), to either publish the service document contents as part of 
the actual AD language; or submit the service document to the OFR for 
approval as referenced material, in which case the FAA may only refer 
to such material in the text of an AD. The AD may refer to the service 
document only if the OFR approved it for incorporation by reference. 
See 1 CFR part 51.
    To allow operators to use later revisions of the referenced 
document (issued after publication of the AD), either the FAA must 
revise the AD to reference specific later revisions, or operators must 
request approval to use later revisions as an alternative method of 
compliance with this AD under the provisions of paragraph (j) of this 
AD.

Clarification of Steps in the Service Information

    Boeing contacted the FAA and stated that there is an error in 
Boeing Alert Requirements Bulletin 757-27A0158 RB, dated July 9, 2020, 
and that the service information would be revised. Boeing stated that 
the reason for the service information revision is that step 2 in the 
figure 4 table incorrectly states to drill six holes, while the graphic 
in figure 4 accurately shows to only drill two holes.
    The FAA has added paragraph (h)(2) of this AD to state, ``Where 
Boeing Alert Requirements Bulletin 757-27A0158 RB, dated July 9, 2020, 
specifies in figure 4 (sheet 3 of 3), step 2, to drill a quantity of 
six holes, this AD requires drilling two holes.'' The FAA has also 
moved the content of paragraph (h) of the proposed AD to paragraph 
(h)(1) of this AD.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
received, and determined that air safety and the public interest 
require adopting this AD with the changes described previously, and 
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.
    The FAA also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Boeing Alert Requirements Bulletin 757-27A0158 RB, 
dated July 9, 2020. This service information describes procedures for 
installing a new relay bracket assembly, making changes to the wire 
bundles for the SCMs, installing new SCMs, measuring the clearance 
between a wire bundle and the top of new relay bracket assembly, 
changing certain wire bundles, repetitive operational tests of the 
spoiler inhibit function, and applicable on-condition actions. On-
condition actions include installing a new protective sleeve, heat 
shrinkable to the wire bundle, doing a landing configurations warning 
module landing flap tests, and doing a system test for the SCMs. 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 626 airplanes 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

    The FAA has determined that 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.
