SUPPLEMENTARY INFORMATION: Background The FAA issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to supersede AD 2022–04–04, Amendment 39–21945 (87 FR 9435, February 22, 2022) (AD 2022–04–04). AD 2022–04–04 applied to certain Continental Model C–125, C145, IO–360, IO–470, IO–520, IO–550, O–300, O–470, TSIO–360, TSIO–520 series engines with a certain oil filter adapter installed. The SNPRM published in the Federal Register on June 2, 2023 (88 FR 36258). The SNPRM was prompted by a comment from an individual commenter noting that certain engine models were missing from the applicability in the notice of proposed rulemaking (NPRM). The commenter also specified that the referenced service information in the NPRM has been revised by the manufacturer. In response to this comment, the FAA determined that additional model engines are affected by the unsafe condition and, as a result, should be added to the applicability paragraph of this AD. The FAA also discovered that certain model engines, with permold type crankcases, were inadvertently included in the applicability paragraph of the NPRM, which the FAA removed in the SNPRM. In the SNPRM, the FAA proposed to require replacing the fiber gasket with a copper or stainless steel PTFE gasket. The FAA also proposed to revise the applicability to include Continental model engines equipped with an F&M or a Stratus oil filter adapter installed per Supplemental Type Certificate SE8409SW, SE09356SC, or SE10348SC. In addition, the FAA also proposed to include the revised service information. The FAA is issuing this AD to address the unsafe condition on these products. 65121 Discussion of Final Airworthiness Directive Comments The FAA received no comments on the SNPRM or on the determination of the costs. Conclusion The FAA reviewed the relevant data and determined that air safety requires adoption of the AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these products. Except for minor editorial changes, this AD is adopted as proposed in the SNPRM. Related Service Information Under 1 CFR Part 51 The FAA reviewed Stratus Mandatory Service Bulletin SB–001 Rev C, dated June 16, 2022, which specifies procedures for removing a fiber gasket and replacing it with a copper gasket, P/ N AN900–28 or P/N AN900–29, or a stainless steel PTFE gasket, P/N ST07, as an improved alternative to the copper gasket. 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 6,300 engines installed on airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ddrumheller on DSK120RN23PROD with RULES1 ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Replace fiber gasket with copper gasket or stainless steel PTFE gasket. 2.5 work-hours × $85 per hour = $212.50 ..... $34 $246.50 $1,552,950 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 VerDate Sep<11>2014 16:08 Sep 20, 2023 Jkt 259001 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 PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 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.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a supplemental notice of proposed rulemaking (SNPRM) 
to amend 14 CFR part 39 to supersede AD 2022-04-04, Amendment 39-21945 
(87 FR 9435, February 22, 2022) (AD 2022-04-04). AD 2022-04-04 applied 
to certain Continental Model C-125, C145, IO-360, IO-470, IO-520, IO-
550, O-300, O-470, TSIO-360, TSIO-520 series engines with a certain oil 
filter adapter installed. The SNPRM published in the Federal Register 
on June 2, 2023 (88 FR 36258). The SNPRM was prompted by a comment from 
an individual commenter noting that certain engine models were missing 
from the applicability in the notice of proposed rulemaking (NPRM). The 
commenter also specified that the referenced service information in the 
NPRM has been revised by the manufacturer. In response to this comment, 
the FAA determined that additional model engines are affected by the 
unsafe condition and, as a result, should be added to the applicability 
paragraph of this AD. The FAA also discovered that certain model 
engines, with permold type crankcases, were inadvertently included in 
the applicability paragraph of the NPRM, which the FAA removed in the 
SNPRM. In the SNPRM, the FAA proposed to require replacing the fiber 
gasket with a copper or stainless steel PTFE gasket. The FAA also 
proposed to revise the applicability to include Continental model 
engines equipped with an F&M or a Stratus oil filter adapter installed 
per Supplemental Type Certificate SE8409SW, SE09356SC, or SE10348SC. In 
addition, the FAA also proposed to include the revised service 
information. The FAA is issuing this AD to address the unsafe condition 
on these products.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the SNPRM or on the determination 
of the costs.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
requires adoption of the AD as proposed. Accordingly, the FAA is 
issuing this AD to address the unsafe condition on these products. 
Except for minor editorial changes, this AD is adopted as proposed in 
the SNPRM.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Stratus Mandatory Service Bulletin SB-001 Rev C, 
dated June 16, 2022, which specifies procedures for removing a fiber 
gasket and replacing it with a copper gasket, P/N AN900-28 or P/N 
AN900-29, or a stainless steel PTFE gasket, P/N ST07, as an improved 
alternative to the copper gasket.
    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 6,300 engines installed on 
airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this AD:

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.
