Airworthiness Directives; Bell Helicopter Textron, Inc. (Bell) 
Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2017-15-02 for 
Bell Model 212 and 412 helicopters. AD 2017-15-02 required replacing 
certain oil and fuel check valves and prohibited installing them on any 
helicopter. This AD retains the requirements of AD 2017-15-02 and adds 
certain model helicopters to the applicability. This AD was prompted by 
the discovery of an error in the affected models. We are issuing this 
AD to address the unsafe condition on these products.

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 http://www.regulations.gov, 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.
