SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain Continental
Aerospace Technologies, Inc. (Type Certificate previously held by
Continental Motors, Inc., and Teledyne Continental Motors) C-125-1, C-
125-2, C145-2, C145-2H, IO-360-C, IO-360-D, IO-360-DB, IO-360-H, IO-
360-HB, IO-360-K, IO-360-KB, IO-470-E, IO-470-S, IO-550-B, IO-550-G, 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-520-C, TSIO-520-CE,
TSIO-520-E, TSIO-520-UB model reciprocating engines; and Continental
Motors (Type Certificate previously held by Teledyne Continental
Motors) IO-520-A, IO-520-B, IO-520-BA, IO-520-BB, IO-520-C, IO-520-D,
IO-520-J, and IO-520-L model reciprocating engines. The NPRM published
in the Federal Register on October 12, 2021 (86 FR 56658). The NPRM was
prompted by reports of two accidents that were the result of power loss
due to oil starvation. The first was a fatal accident on May 1, 2019,
in Mill Creek California, involving a Cessna 182P airplane with an
installed Continental Motors O-470-S engine. The National
Transportation Safety Board's preliminary accident investigation
report, docket number WPR19FA126, identified evidence of improperly
maintained or installed oil filter adapters. An improperly maintained
or installed oil filter adapter may lead to failure of the fiber
gasket, which may result in oil loss or oil starvation. Based on the
investigation, the manufacturer determined the need to replace the
fiber gasket with a copper gasket. In the NPRM, the FAA proposed to
require removal of the fiber gasket and replacement with a copper
gasket.

The FAA is issuing this AD to address the unsafe condition on these
products.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from two individual commenters. The
following presents the comments received on the NPRM and the FAA's
response to each comment.
Request To Broaden the Scope
One commenter compared the NPRM to a previous AD that the FAA
issued in 1996, AD 96-12-22 (61 FR 30501, June 17, 1996), to address
loose or separated oil filter adapters. The commenter requested that
the FAA consider issuing an AD with a broader scope, such as a remote-
mounted oil filter secured to the firewall, as a more permanent
solution. The commenter reasoned that a remote-mounted filter would
reduce the potential for accidents caused by oil starvation and power
loss.
The FAA issued AD 96-12-22 to address an unsafe condition caused by
adapter-to-oil pump threads fragmenting, resulting in loose or
separated oil filter adapters. Like AD 96-12-22, a remote-mounted oil
filter secured to the firewall is not needed to correct the unsafe
condition prompting this AD, which is power loss due to oil starvation.
The unsafe condition that prompted this AD was caused by failure of the
fiber gasket due to improperly maintained or installed oil filter
adapters. Therefore, this AD requires replacing the fiber gasket with a
copper gasket.
Suggestion To Design a Better Gasket
One commenter requested that the FAA make the manufacturer design a
better gasket, installed with a torque commensurate with the torqued
material, such as fiber gasket material similar to the gaskets used in
propeller governors. The commenter stated that the gaskets used in
propeller governors are manufactured with an oil-resistant outer layer,
a stainless steel mesh center layer, and an oil-resistant inner layer.
The commenter reasoned that these gaskets would cover the entire
sealing faces of the oil filter adapter and the oil pump, unlike the
copper gasket, which uses only a portion of the sealing area.
The FAA does not agree that using fiber gasket material similar to
the gaskets used in propeller governors is necessary to address the
unsafe condition, which is power loss due to oil starvation. The unsafe
condition that prompted this AD was caused by failure of the fiber
gasket due to improperly maintained or installed oil filter adapters,
not the amount of torque applied to a specific gasket material.
Additionally, as part of the certification process, the manufacturer
has analyzed and tested the copper gasket and found it meets the design
intent.
Conclusion
The FAA reviewed the relevant data, considered any comments
received, and determined that air safety requires adopting this AD as
proposed. Accordingly, the FAA is issuing this AD to address the unsafe
condition on these products. This AD is adopted as proposed in the
NPRM.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Stratus Tool Technologies Mandatory Service
Bulletin (MSB) SB-001 Rev B, dated June 17, 2021. This MSB specifies
procedures for removing a fiber gasket and replacing it with a 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 ADDRESSES.
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
----------------------------------------------------------------------------------------------------------------
Replace fiber gasket with copper 2.5 work-hours x $85 per $34 $246.50 $1,552,950
gasket. hour = $212.50.
----------------------------------------------------------------------------------------------------------------
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.
