Airworthiness Directives; Bell Textron Canada Limited (Type Certificate Previously Held by Bell Helicopter Textron Canada Limited) Helicopters, 24485-24487 [2021-09278]

Download as PDF Federal Register / Vol. 86, No. 87 / Friday, May 7, 2021 / Rules and Regulations 49297, 49311) and is supported by the discussion in the preamble of the December 2020 final rule.1 DOE published a correction notice on January 19, 2021 (‘‘January 2021 correction notice’’) responding to specific comments submitted by the Pacific Gas and Electric Company, San Diego Gas and Electric, and Southern California Edison in response to DOE’s notice of proposed rulemaking published on August 13, 2020, which were inadvertently omitted from the December 2020 final rule. 86 FR 4883. DOE considered these comments and determined that in most instances, these comments raised issues substantially similar to those raised by other commenters that DOE had considered and addressed in the December 2020 final rule. To the extent that these comments raised issues not explicitly addressed in the December 2020 final rule, DOE determined that the comments did not alter any of the conclusions reached in support of the final rule and would not have resulted in an outcome different than as set forth in the final rule. Id. This omission in the amended regulatory text also appeared in the January 2021 correction. The substance of this final rule correction is distinct from the substance of the January 2021 correction notice. II. Need for Correction As published, the regulatory text in the December 2020 final rule may result in confusion as to the required test procedure for determining cycle time due to the omission of the distinction that the 30-minute cycle time for clothes dryers is determined when conducting the test procedure at appendix D2. Because this final rule would simply correct errors in the text without making substantive changes in the December 2020 final rule, the changes addressed in this document are technical in nature. 1 The separate product classes for clothes dryers were based, in part, on data generated from testing in accordance with appendix D2. 85 FR 81359, 81360. Additionally, as explained in the December 2020 final rule, the clothes dryer test procedure at 10 CFR part 430, subpart B, appendix D1 does not provide data that can be used to determine a ‘‘cycle time’’ because the drying cycle is artificially terminated. As explained in the final rule, the artificially-terminated cycle has a field use factor applied to calculate representative energy consumption. 85 FR 81359, 81360 (footnote 2). DOE relied on appendix D2 as the basis for defining the 30-minute cycle time distinction because appendix D2 provides representative energy use and a corresponding cycle time, as the cycle is run from start to completion without being artificially terminated. Id. VerDate Sep<11>2014 16:08 May 06, 2021 Jkt 253001 24485 III. Procedural Issues and Regulatory Review the legal effect of this document upon publication in the Federal Register. DOE has concluded that the determinations made pursuant to the various procedural requirements applicable to the December 2020 final rule remain unchanged for this final rule technical correction. These determinations are set forth in the December 2020 final rule. 85 FR 81359, 81373. Pursuant to the Administrative Procedure Act, 5 U.S.C. 553(b)(3)(B), DOE finds that there is good cause to not issue a separate notice to solicit public comment on the changes contained in this document. Issuing a separate notice to solicit public comment would be impracticable, unnecessary, and contrary to the public interest. Neither the errors nor the corrections in this document affect the substance of the December 2020 final rule or any of the conclusions reached in support of the final rule. Providing prior notice and an opportunity for public comment on correcting objective, typographical errors that do not change the substance of the test procedure serves no useful purpose. Further, this rule correcting a regulatory text omission makes nonsubstantive changes to the test procedure. As such, this rule is not subject to the 30-day delay in effective date requirement of 5 U.S.C. 553(d) otherwise applicable to rules that make substantive changes.

SUPPLEMENTARY INFORMATION: Background The FAA issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 by adding an AD that would apply to Bell Textron Canada Limited (type certificate previously held by Bell Helicopter Textron Canada Limited) Model 206L, 206L–1, 206L–3, and 206L–4 helicopters, with certain switch units part number (P/N) 206–063–613–003 VerDate Sep<11>2014 16:08 May 06, 2021 Jkt 253001 installed. The SNPRM published in the Federal Register on March 12, 2021 (86 FR 14020). The FAA preceded the SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on June 22, 2006 (71 FR 35836). The NPRM was prompted by Canadian AD CF–2004–24, dated November 24, 2004, issued by Transport Canada, which is the aviation authority for Canada, to correct an unsafe condition for Model 206L series helicopters. Transport Canada advised that eight low fuel level detectors of listed serial numbers (S/Ns) may have been installed on Model 206L series helicopters. These detectors could hang in the high position and fail to indicate the low fuel condition. Accordingly, Transport Canada advised removing the affected switch units from service. The SNPRM was prompted by a significant lapse of time since publication of the NPRM. The SNPRM also revised the NPRM by updating the type certificate holder’s name, updating the estimated cost information, clarifying and expanding the applicability, clarifying the requirements, adding a compliance time, adding parts installation prohibitions, and updating the AD format. The SNPRM proposed to require removing switch unit P/N 206–063– 613–003 with S/N 1413, 1414, 1415, 1424, 1428, 1430, 1432, and 1433 from service and prohibit installing those switch units. The SNPRM proposed to require accomplishing an operational test of switch unit P/N 206–063–613– 003 with a missing or illegible switch unit S/N or with an S/N that cannot be determined, and if the operational test fails, removing the switch unit from service. The SNPRM also proposed to prohibit installing switch unit P/N 206– 063–613–003 with a missing or illegible switch unit S/N or with an S/N that cannot be determined unless it passes an operational test. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the SNPRM or on the determination of the costs. Conclusion These helicopters have been approved by the aviation authority of Canada and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with Canada, Transport Canada, its technical representative, has notified the FAA of the unsafe condition PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 described in its AD. The FAA reviewed the relevant data 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 helicopters. Related Service Information The FAA reviewed Bell Helicopter Textron Alert Service Bulletin No. 206L–04–132, Revision A, dated October 4, 2004. This service information specifies procedures for determining whether any of eight specified serial-numbered detector switch units are installed because they may fail to indicate a low fuel condition. If the S/N is missing or unreadable, the service information specifies inspecting the switch unit to determine if it is an affected switch unit. The service information also specifies removing each affected switch unit. Differences Between This AD and the Transport Canada This AD applies to switch units with a missing or illegible S/N or with an S/N that cannot be determined, and requires certain actions for those switch units, whereas the Transport Canada AD does not. Costs of Compliance The FAA estimates that this AD affects up to 558 helicopters of U.S. Registry. Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates the following costs to comply with this AD. Replacing a switch unit takes about 4 work-hours and parts cost about $921 for an estimated cost of $1,261 per switch unit and up to $703,638 for the U.S. fleet. Accomplishing an operational test takes about 4 work-hours for an estimated cost of $340 per switch unit and up to $189,720 for the U.S. fleet. 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 E:\FR\FM\07MYR1.SGM 07MYR1 Federal Register / Vol. 86, No. 87 / Friday, May 7, 2021 / Rules and Regulations that authority because it addresses an unsafe condition that is likely to exist or develop on helicopters 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.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a supplemental notice of proposed rulemaking (SNPRM) 
to amend 14 CFR part 39 by adding an AD that would apply to Bell 
Textron Canada Limited (type certificate previously held by Bell 
Helicopter Textron Canada Limited) Model 206L, 206L-1, 206L-3, and 
206L-4 helicopters, with certain switch units part number (P/N) 206-
063-613-003 installed. The SNPRM published in the Federal Register on 
March 12, 2021 (86 FR 14020). The FAA preceded the SNPRM with a notice 
of proposed rulemaking (NPRM) that published in the Federal Register on 
June 22, 2006 (71 FR 35836).
    The NPRM was prompted by Canadian AD CF-2004-24, dated November 24, 
2004, issued by Transport Canada, which is the aviation authority for 
Canada, to correct an unsafe condition for Model 206L series 
helicopters. Transport Canada advised that eight low fuel level 
detectors of listed serial numbers (S/Ns) may have been installed on 
Model 206L series helicopters. These detectors could hang in the high 
position and fail to indicate the low fuel condition. Accordingly, 
Transport Canada advised removing the affected switch units from 
service.
    The SNPRM was prompted by a significant lapse of time since 
publication of the NPRM. The SNPRM also revised the NPRM by updating 
the type certificate holder's name, updating the estimated cost 
information, clarifying and expanding the applicability, clarifying the 
requirements, adding a compliance time, adding parts installation 
prohibitions, and updating the AD format.
    The SNPRM proposed to require removing switch unit P/N 206-063-613-
003 with S/N 1413, 1414, 1415, 1424, 1428, 1430, 1432, and 1433 from 
service and prohibit installing those switch units. The SNPRM proposed 
to require accomplishing an operational test of switch unit P/N 206-
063-613-003 with a missing or illegible switch unit S/N or with an S/N 
that cannot be determined, and if the operational test fails, removing 
the switch unit from service. The SNPRM also proposed to prohibit 
installing switch unit P/N 206-063-613-003 with a missing or illegible 
switch unit S/N or with an S/N that cannot be determined unless it 
passes an operational test.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the SNPRM or on the determination 
of the costs.

Conclusion

    These helicopters have been approved by the aviation authority of 
Canada and are approved for operation in the United States. Pursuant to 
the FAA's bilateral agreement with Canada, Transport Canada, its 
technical representative, has notified the FAA of the unsafe condition 
described in its AD. The FAA reviewed the relevant data 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 
helicopters.

Related Service Information

    The FAA reviewed Bell Helicopter Textron Alert Service Bulletin No. 
206L-04-132, Revision A, dated October 4, 2004. This service 
information specifies procedures for determining whether any of eight 
specified serial-numbered detector switch units are installed because 
they may fail to indicate a low fuel condition. If the S/N is missing 
or unreadable, the service information specifies inspecting the switch 
unit to determine if it is an affected switch unit. The service 
information also specifies removing each affected switch unit.

Differences Between This AD and the Transport Canada

    This AD applies to switch units with a missing or illegible S/N or 
with an S/N that cannot be determined, and requires certain actions for 
those switch units, whereas the Transport Canada AD does not.

Costs of Compliance

    The FAA estimates that this AD affects up to 558 helicopters of 
U.S. Registry. Labor rates are estimated at $85 per work-hour. Based on 
these numbers, the FAA estimates the following costs to comply with 
this AD.
    Replacing a switch unit takes about 4 work-hours and parts cost 
about $921 for an estimated cost of $1,261 per switch unit and up to 
$703,638 for the U.S. fleet. Accomplishing an operational test takes 
about 4 work-hours for an estimated cost of $340 per switch unit and up 
to $189,720 for the U.S. fleet.

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

[[Page 24487]]

that authority because it addresses an unsafe condition that is likely 
to exist or develop on helicopters 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,

1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

2021-10-08 Bell Textron Canada Limited (Type Certificate Previously 
Held by Bell Helicopter Textron Canada Limited): Amendment 39-21541 
Docket No. FAA-2006-25084; Project Identifier 2005-SW-38-AD.

(a) Effective Date

    This airworthiness directive (AD) is effective June 11, 2021.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bell Textron Canada Limited (type certificate 
previously held by Bell Helicopter Textron Canada Limited) Model 
206L, 206L-1, 206L-3, and 206L-4 helicopters, certificated in any 
category, with a low fuel level detector switch unit (switch unit) 
part number (P/N) 206-063-613-003:
    (1) With a switch unit serial number (S/N) 1413, 1414, 1415, 
1424, 1428, 1430, 1432, or 1433 installed, or
    (2) With a missing or illegible switch unit S/N or if the S/N 
cannot be determined, installed.

    Note 1 to paragraph (c): Helicopters with a 206L-1+ designation 
are Model 206L-1 helicopters. Helicopters with a 206L-3+ designation 
are Model 206L-3 helicopters.
    Note 2 to paragraph (c): The switch unit is located on the aft 
fuel boost pump assembly. The P/N and S/N for the switch unit could 
be on the outside face of the attachment flange, in the cross 
hatched area of the switch unit.

(d) Subject

    Joint Aircraft Service Component (JASC) Code: 2842, Fuel 
Quantity Sensor.

(e) Unsafe Condition

    This AD was prompted by a manufacturing flaw that could cause a 
switch unit to hang in the high position and fail to indicate a low 
fuel condition. The FAA is issuing this AD to prevent failure of the 
switch unit to indicate a low fuel condition that could lead to fuel 
exhaustion and which if not addressed, could result in a subsequent 
forced landing.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    (1) For a switch unit identified in paragraph (c)(1) of this AD, 
on or before the next 100-hour time-in-service inspection after the 
effective date of this AD, remove the switch unit from service.
    (2) For a switch unit identified in paragraph (c)(2) of this AD, 
on or before the next 100-hour time-in-service inspection after the 
effective date of this AD:
    (i) Determine the color of the switch unit mounting flange. If 
the mounting flange color is any color other than red, determine the 
purchase date. If the purchase date of the switch unit is between 
April 19 and July 26, 2004, or cannot be determined, do an 
operational test.
    (ii) If the switch unit fails the operational test, before 
further flight, remove the switch unit from service.
    (3) As of the effective date of this AD, do not install a switch 
unit identified in paragraph (c)(1) of this AD on any helicopter.
    (4) As of the effective date of this AD, do not install a switch 
unit identified in paragraph (c)(2) of this AD on any helicopter 
unless the actions in paragraphs (g)(2)(i) and (ii) of this AD have 
been accomplished.

(h) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, International Validation Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information
