Abstract
The FAA is superseding Airworthiness Directive (AD) 2022-04-04 for certain Continental Aerospace Technologies, Inc. (Continental) Model C-125, C145, IO-360, IO-470, IO-550, O-300, O-470, TSIO-360, and TSIO-520 series engines and certain Continental Motors IO-520 series engines with a certain oil filter adapter installed. AD 2022-04-04 required replacing the oil filter adapter fiber gasket (fiber gasket) with an oil filter adapter copper gasket (copper gasket). This AD was prompted by reports of two accidents that were the result of power loss due to oil starvation. This AD requires replacing the fiber gasket with a copper gasket or a stainless steel embedded within polytetrafluoroethylene gasket (stainless steel PTFE gasket). This AD also revises the applicability to include Continental model engines equipped with an F&M Enterprises, Inc. (F&M) or a Stratus Tool Technologies, LLC (Stratus) oil filter adapter installed. The FAA is issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; Continental Aerospace Technologies,
Inc. Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2022-04-04
for certain Continental Aerospace Technologies, Inc. (Continental)
Model C-125, C145, IO-360, IO-470, IO-550, O-300, O-470, TSIO-360, and
TSIO-520 series engines and certain Continental Motors IO-520 series
engines with a certain oil filter adapter installed. AD 2022-04-04
required replacing the oil filter adapter fiber gasket (fiber gasket)
with an oil filter adapter copper gasket (copper gasket). This AD was
prompted by reports of two accidents that were the result of power loss
due to oil starvation. This AD requires replacing the fiber gasket with
a copper gasket or a stainless steel embedded within
polytetrafluoroethylene gasket (stainless steel PTFE gasket). This AD
also revises the applicability to include Continental model engines
equipped with an F&M Enterprises, Inc. (F&M) or a Stratus Tool
Technologies, LLC (Stratus) oil filter adapter installed. The FAA is
issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective October 26, 2023.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of October 26,
2023.

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:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------

gasket.
----------------------------------------------------------------------------------------------------------------
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.
