[Docket No. FAA-2022-1159; Project Identifier AD-2022-00692-E]
RIN 2120-AA64

Airworthiness Directives; Continental Aerospace Technologies,
Inc. Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (SNPRM).

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

SUMMARY: The FAA is revising a notice of proposed rulemaking (NPRM)
that applied to certain Continental Aerospace Technologies, Inc.
(Continental) Model C-125, C145, GO-300, IO-360, IO-470, IO-520, IO-
550, O-300, O-470, TSIO-360, and TSIO-520 series engines with a certain
oil filter adapter installed. The NPRM proposed to supersede AD 2022-
04-04. This action revises the NPRM by updating the applicability to
include Continental model engines with certain oil filter adapters
installed and updating the service information references. The FAA is
proposing this airworthiness directive (AD) to address the unsafe
condition on these products. Since these actions would impose an
additional burden by expanding the applicability, the agency is
requesting comments on this SNPRM.

Background

    The FAA issued an NPRM to amend 14 CFR part 39 by adding an AD that
would apply to certain Continental Model C-125-1, C-125-2, C145-2,
C145-2H, GO-300-A, GO-300-B, GO-300-C, GO-300-D, GO-300-E, GO-300-F,
IO-360-C, IO-360-D, IO-360-DB, IO-360-H, IO-360-HB, IO-360-K, IO-360-
KB, IO-470-C, IO-470-D, IO-470-H, IO-470-J, IO-470-K, IO-470-L, IO-470-
M, IO-470-N, IO-470-S, IO-470-U, IO-470-V, IO-520-A, IO-520-D, IO-520-
F, IO-520-J, IO-520-K, IO-520-L, IO-550-D, IO-550-E, IO-550-F, O-300-A,
O-300-B, O-300-C, O-300-D, O-300-E, O-470-A, O-470-B, O-470-G, O-470-J,
O-470-K, O-470-L, O-470-M, O-470-N, O-470-R, O-470-S, O-470-U, O-470-
11, O-470-15, TSIO-360-E, TSIO-360-EB, TSIO-360-F, TSIO-360-FB, TSIO-
360-GB, TSIO-360-LB, TSIO-360-MB, TSIO-360-SB, TSIO-470-C, TSIO-520-C,
TSIO-520-G, and TSIO-520-H engines with a certain oil filter adapter
installed. The NPRM published in the Federal Register on September 14,
2022 (87 FR 56286). The NPRM was prompted by

reports of two accidents that were the result of power loss due to oil
starvation. In the NPRM, the FAA proposed to supersede and retain
certain requirements of AD 2022-04-04, Amendment 39-21945 (87 FR 9435,
February 22, 2022). In the NPRM, the FAA also proposed to require
replacing the oil filter adapter fiber gasket (fiber gasket) with an
oil filter adapter copper gasket (copper gasket) or a stainless steel
embedded within polytetrafluoroethylene gasket (stainless steel PTFE
gasket). In the NPRM, the FAA also proposed to revise the applicability
by adding and removing certain model engines and revise the special
flight permit paragraph by expanding the limitations. In the NPRM, the
FAA also proposed to update the required actions by adding an
additional part-numbered stainless steel PTFE gasket as a replacement
part.

Actions Since the NPRM Was Issued

    Since the FAA issued the NPRM, the FAA received a comment from an
individual commenter noting that certain engine models were missing
from the NPRM's applicability. 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 the NPRM. The
FAA also discovered that certain model engines, with permold type
crankcases, were inadvertently included in the applicability paragraph
of the NPRM. Therefore, the FAA revised the applicability of this
proposed AD 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 per Supplemental Type Certificate (STC)
SE8409SW, SE09356SC, or SE10348SC. In addition, the manufacturer has
published revised service information, which includes the alternative
use of a stainless steel PTFE gasket, part number (P/N) ST07, as a
replacement part.

Comments

    The following discussion presents the comments received on the NPRM
and the FAA's response.

Revision to the Applicability

    An individual commenter noted that paragraph (c), Applicability, of
the NPRM, excluded Continental Model IO-360-G, IO-360-J, IO-360-JB, IO-
360-LB, IO-470-E, and IO-470-F engines. The commenter also noted that a
review of Continental's online Illustrated Parts Catalog shows that
these model engines use the same accessory housing as other IO-360
model engines, which can accommodate a Stratus oil filter adapter that
is included in the NPRM.
    The FAA agrees and has revised paragraph (c), Applicability, of
this proposed AD to include any Continental model engine equipped with
an F&M or a Stratus oil filter adapter installed per STC SE8409SW,
SE09356SC, or SE10348SC.

Request To Reference Revised Service Information

    An individual commenter stated that the Stratus Tool Technologies
Mandatory Service Bulletin SB-001 Rev B has been updated to Rev C,
which allows the use of a stainless steel PTFE gasket, P/N ST07. The
FAA infers that the commenter is requesting that this proposed AD be
revised to reference Stratus Tool Technologies Mandatory Service
Bulletin SB-001 Rev C, dated June 16, 2022 (the NPRM refers to Stratus
Tool Technologies Mandatory Service Bulletin SB-001 Rev B, dated June
17, 2021).
    The FAA agrees and has revised this proposed AD to include
reference to Stratus Tool Technologies Mandatory Service Bulletin SB-
001 Rev C, dated June 16, 2022, and added paragraph (i), Credit for
Previous Actions, which would provide credit for the replacement of a
fiber gasket with a copper gasket in accordance with Stratus Tool
Technologies Mandatory Service Bulletin SB-001 Rev B, dated June 17,
2021.

FAA's Determination

    The FAA is proposing this AD after determining the unsafe condition
described previously is likely to exist or develop in other products of
the same type design. Certain changes described above expand the scope
of the NPRM. As a result, it is necessary to reopen the comment period
to provide additional opportunity for the public to comment on this
SNPRM.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Stratus Tool Technologies Mandatory Service
Bulletin SB-001 Rev C, dated June 16, 2022. This service information
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.

Proposed AD Requirements in This SNPRM

    This proposed AD would retain certain requirements of AD 2022-04-
04. This proposed AD would require replacing the fiber gasket with a
copper or stainless steel PTFE gasket. This proposed AD would also
revise the applicability to include Continental model engines equipped
with an F&M or a Stratus oil filter adapter installed per STC SE8409SW,
SE09356SC, or SE10348SC in accordance with the service information
previously described.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would
affect 6,300 engines installed on airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this proposed
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 determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
    (1) Is not a ``significant regulatory action'' under Executive
Order 12866,
    (2) Will not affect intrastate aviation in, 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.
