Transport Canada advises that part numbered 209– 062–520–001 check valves manufactured by Circor Aerospace as replacement parts have been found cracked or leaking on several helicopters. According to Transport Canada, these check valves are used in the lubrication systems of the Model 429 engines and main rotor transmission and the Model 427 engines. Finally, Transport Canada advises that loss of lubrication may cause catastrophic failure of the transmission or the engine, which could result in loss of control of the helicopter. Transport Canada AD No. CF–2015– 29 requires a one-time inspection of the transmission and engine check valves for cracks and leaks. If there is a crack or leaking fluid, the Transport Canada AD requires replacing the check valve before further flight. Otherwise, the Transport Canada AD requires replacing each check valve within 60 days for the main rotor transmission and one year for the engine with a check valve marked ‘‘TQL’’ as shown in the manufacturer’s service bulletins. The Transport Canada AD also prohibits installing a part number (P/N) 209–062– 520–001 check valve on any helicopter if the check valve was manufactured by Circor Aerospace, marked ‘‘Circle Seal,’’ and manufactured between October 2011 and March 2015. VerDate Sep<11>2014 18:28 Sep 29, 2016 Jkt 238001 FAA’s Determination These helicopters have been approved by the aviation authority of Canada and are approved for operation in the United States. Pursuant to our bilateral agreement with Canada, Transport Canada, its technical representative, has notified us of the unsafe condition described in its AD. We are issuing this AD because we evaluated all information provided by Transport Canada and determined the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs. Related Service Information We reviewed Bell Alert Service Bulletin (ASB) 427–15–37 for Model 427 helicopters and Bell ASB 429–15– 23 for Model 429 helicopters, both dated September 4, 2015. Both ASBs describe procedures for inspecting and replacing the check valve, P/N 209–062–520–001, installed on certain serial-numbered Model 427 and Model 429 helicopters. AD Requirements This AD requires, within 25 hours time-in-service (TIS), replacing the transmission and engine oil check valves. This AD also prohibits installing a check valve P/N 209–062–520–001 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) on any helicopter. Differences Between This AD and the Transport Canada AD The Transport Canada AD requires inspecting the valves for cracks and leaks to determine when they must be replaced. This AD requires replacing all check valves within 25 hours TIS. Costs of Compliance We estimate that this AD affects 105 (29 Model 427 and 76 Model 429) 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 (transmission or engine) will require about 1 work-hour, and required parts will cost $85. For the Model 427, we estimate a total cost of $170 per helicopter and $4,930 for the U.S. fleet. For the Model 429, we estimate a total cost of $340 per helicopter and $25,840 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, PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 67103 we have included all costs in our cost estimate. FAA’s Justification and Determination of the Effective Date Providing an opportunity for public comments prior to adopting these AD requirements would delay implementing the safety actions needed to correct this known unsafe condition. Therefore, we find that the risk to the flying public justifies waiving notice and comment prior to the 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 offshore transportation. Since an unsafe condition exists that requires the immediate adoption of this AD, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in less than 30 days. 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 We 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, 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); E:\FR\FM\30SER1.SGM 30SER1 67104 Federal Register / Vol. 81, No. 190 / Friday, September 30, 2016 / Rules and Regulations 3. Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; 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. We prepared an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

Discussion

    On December 7, 2015, Transport Canada issued AD No. CF-2015-29 to 
correct an unsafe condition for certain serial-numbered Bell Model 427 
and Model 429 helicopters. Transport Canada advises that part numbered 
209-062-520-001 check valves manufactured by Circor Aerospace as 
replacement parts have been found cracked or leaking on several 
helicopters. According to Transport Canada, these check valves are used 
in the lubrication systems of the Model 429 engines and main rotor 
transmission and the Model 427 engines. Finally, Transport Canada 
advises that loss of lubrication may cause catastrophic failure of the 
transmission or the engine, which could result in loss of control of 
the helicopter.
    Transport Canada AD No. CF-2015-29 requires a one-time inspection 
of the transmission and engine check valves for cracks and leaks. If 
there is a crack or leaking fluid, the Transport Canada AD requires 
replacing the check valve before further flight. Otherwise, the 
Transport Canada AD requires replacing each check valve within 60 days 
for the main rotor transmission and one year for the engine with a 
check valve marked ``TQL'' as shown in the manufacturer's service 
bulletins. The Transport Canada AD also prohibits installing a part 
number (P/N) 209-062-520-001 check valve on any helicopter if the check 
valve was manufactured by Circor Aerospace, marked ``Circle Seal,'' and 
manufactured between October 2011 and March 2015.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Canada and are approved for operation in the United States. Pursuant to 
our bilateral agreement with Canada, Transport Canada, its technical 
representative, has notified us of the unsafe condition described in 
its AD. We are issuing this AD because we evaluated all information 
provided by Transport Canada and determined the unsafe condition exists 
and is likely to exist or develop on other helicopters of these same 
type designs.

Related Service Information

    We reviewed Bell Alert Service Bulletin (ASB) 427-15-37 for Model 
427 helicopters and Bell ASB 429-15-23 for Model 429 helicopters, both 
dated September 4, 2015. Both ASBs describe procedures for inspecting 
and replacing the check valve, P/N 209-062-520-001, installed on 
certain serial-numbered Model 427 and Model 429 helicopters.

AD Requirements

    This AD requires, within 25 hours time-in-service (TIS), replacing 
the transmission and engine oil check valves.
    This AD also prohibits installing a check valve P/N 209-062-520-001 
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) on any helicopter.

Differences Between This AD and the Transport Canada AD

    The Transport Canada AD requires inspecting the valves for cracks 
and leaks to determine when they must be replaced. This AD requires 
replacing all check valves within 25 hours TIS.

Costs of Compliance

    We estimate that this AD affects 105 (29 Model 427 and 76 Model 
429) 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 (transmission or engine) will require about 1 work-hour, 
and required parts will cost $85. For the Model 427, we estimate a 
total cost of $170 per helicopter and $4,930 for the U.S. fleet. For 
the Model 429, we estimate a total cost of $340 per helicopter and 
$25,840 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.

FAA's Justification and Determination of the Effective Date

    Providing an opportunity for public comments prior to adopting 
these AD requirements would delay implementing the safety actions 
needed to correct this known unsafe condition. Therefore, we find that 
the risk to the flying public justifies waiving notice and comment 
prior to the 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 offshore transportation.
    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we determined that notice and opportunity for 
public comment before issuing this AD are impracticable and that good 
cause exists for making this amendment effective in less than 30 days.

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

    We 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, 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);

[[Page 67104]]

    3. Will not affect intrastate aviation in Alaska to the extent that 
it justifies making a regulatory distinction; 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.
    We prepared an economic evaluation of the estimated costs to comply 
with this AD and placed it in the AD docket.
