Unsafe Condition
The engine oil and fuel check valves may have a condition induced during assembly that can cause the valve body to crack, resulting in oil or fuel leakage. This condition could result in loss of lubrication or fuel to the engine, failure of the engine or a fire, and subsequent loss of control of the helicopter.

SUPPLEMENTARY INFORMATION:
Discussion
We issued AD 2017-15-02, Amendment 39-18962 (82 FR 33439, July 20,
2017), (``AD 2017-15-02''). AD 2017-15-02 applied to Bell Model 212 and
412 helicopters with an engine oil or fuel check valve part number (P/
N) 209-062-520-001 or P/N 209-062-607-001 that was manufactured by
Circor Aerospace, marked ``Circle Seal'' and marked with a
manufacturing date code of ``10/11'' (October 2011) through ``03/15''
(March 2015) installed. AD 2017-15-02 resulted from a report that
certain part numbered 209-062-520-001 check valves manufactured by
Circor Aerospace as replacement parts have been found cracked or
leaking on several Bell Model 427 and Model 429 helicopters. These
check valves may be installed as engine oil check valves on Bell Model
212 helicopters. Similar check valves, part number 209-062-607-001, may
be installed as fuel check valves on Bell Model 212 or 412 helicopters.
These check valves may have a condition induced during assembly that
can cause the valve body to crack, resulting in oil or fuel leakage.
This condition could result in loss of lubrication or fuel to the
engine, failure of the engine or a fire, and subsequent loss of control
of the helicopter. To address this condition, AD 2017-15-02 required
replacing the engine oil and fuel check valves and prohibited
installing an affected check valve on any helicopter.
Actions Since AD 2017-15-02 Was Issued
Since we issued AD 2017-15-02, we discovered an error in that Bell
Model 412CF and 412EP helicopters should have been included in the
applicability of the AD. Additionally, Bell revised its service
information to exclude check valves identified with ``TQL'' regardless
of manufacture date. Check valves marked ``TQL'' were manufactured
using a different process and are not affected by the unsafe condition.
Therefore, we are superseding AD 2017-15-02 to add Bell Model 412CF and
412EP helicopters to the applicability and to exclude check valves
marked ``TQL.''
Related Service Information
We reviewed Bell Alert Service Bulletin (ASB) 212-15-153, Revision
A, dated October 6, 2017 (212-15-153), and Bell ASB 212-15-155,
Revision A, dated October 6, 2017 (212-15-155), for Model 212
helicopters; Bell ASB 412-15-165, Revision A, dated October 6, 2017
(412-15-165), and Bell ASB 412-15-168, Revision A, dated October 6,
2017 (ASB 412-15-168), for Model 412 and 412 EP helicopters; and Bell
ASB 412CF-15-57, Revision A, dated October 6, 2017 (412CF-15-57), and
Bell ASB 412CF-15-59, Revision A, dated October 6, 2017 (412CF-15-59),
for Model 412CF helicopters. ASB 212-15-153, ASB 412-15-165, and ASB
412-CF-15-57 contain procedures for inspecting and replacing engine oil
check valve P/N 209-062-520-001. ASB 212-15-155, ASB 412-15-168, and
ASB
[[Page 42206]]
412CF-15-59 contain procedures for inspecting and replacing fuel check
valve P/N 209-062-607-001. Revision A of the service information
clarifies that check valves identified with ``TQL'' are not affected by
the ASB procedures.
FAA's Determination
We are issuing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of these same type
designs.
AD Requirements
This AD requires, within 25 hours time-in-service (TIS), replacing
the engine oil and fuel check valves. This AD also prohibits installing
on any helicopter a check valve P/N 209-062-520-001 or P/N 209-062-607-
001 that was manufactured by Circor Aerospace, marked ``Circle Seal''
and marked with a manufacturing date code of ``10/11'' (October 2011)
through ``03/15'' (March 2015), except if ``TQL'' is marked next to the
manufacturing date code.
FAA's Justification and Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies waiving notice and comment prior to adoption of this rule
because the actions required by this AD must be accomplished within 25
hours TIS, a very short interval for helicopters used in firefighting
and logging operations. Therefore, we find good cause that notice and
opportunity for prior public comment are impracticable. In addition,
for the reason stated above, we find that good cause exists for making
this amendment effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not provide you with notice and an opportunity to
provide your comments before it becomes effective. However, we invite
you to send any written data, views, or arguments about this final
rule. Send your comments to an address listed under the ADDRESSES
section. Include the docket number FAA-2018-0738 and product identifier
2017-SW-132-AD at the beginning of your comments. We specifically
invite comments on the overall regulatory, economic, environmental, and
energy aspects of this final rule. We will consider all comments
received by the closing date and may amend this final rule because of
those comments.
We will post all comments we receive, without change, to <a href="http://www.regulations.gov">http://www.regulations.gov</a>, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this final rule.
Costs of Compliance
We estimate that this AD affects 161 (59 Model 212 and 102 Model
412) helicopters of U.S. Registry.
We estimate that operators may incur the following costs in order
to comply with this AD. At an average labor rate of $85, replacing each
check valve (engine oil or fuel) will require about 1 work-hour, and
required parts will cost $85. For the Model 212, we estimate a total
cost of $340 per helicopter and $20,060 for the U.S. fleet. For the
Model 412, we estimate a total cost of $170 per helicopter and $17,340
for the U.S. fleet.
According to Bell's service information some of the costs of this
AD may be covered under warranty, thereby reducing the cost impact on
affected individuals. We do not control warranty coverage by Bell.
Accordingly, we have included all costs in our cost estimate.
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.
We are 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) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
