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 Bell Textron Canada Limited (type certificate previously held by Bell Helicopter Textron Canada Limited) Model 505 helicopters. The NPRM published in the Federal Register on September 20, 2021 (86 FR 52109). In the NPRM, the FAA proposed to require revising the existing RFM for your helicopter. Incorporating the RFM revision may be performed by the owner/operator (pilot) holding at least a private pilot certificate and must be entered into the aircraft records showing compliance with this AD in accordance with 14 CFR 43.9(a)(1) through (4) and 14 CFR 91.417(a)(2)(v). The record must be maintained as required by 14 CFR 91.417, 121.380, or 135.439. This is an exception to the FAA’s standard maintenance regulations. The NPRM was prompted by Canadian AD CF–2019–08, dated March 5, 2019 (Canadian AD CF–2019–08), issued by Transport Canada, which is the aviation authority for Canada, to correct an unsafe condition for Bell Helicopter Textron Canada Limited Model 505 helicopters serial numbers 65011 and subsequent. Transport Canada advises of the need to reduce the altitude limitations for Jet B and JP– 4 wide-cut fuels following unsatisfactory performance of the engine at the original higher altitude limitations with these wide-cut fuels. This condition, if not addressed, could result in low fuel pressure, engine flame-out, or engine power interruption VerDate Sep<11>2014 16:33 Dec 08, 2021 Jkt 256001 (a change in any engine performance parameter—including but not limited to gas generator speed, power turbine speed, main gas temperature, or output torque—outside its normal limits for the prevailing operating conditions). Accordingly, Canadian AD CF–2019– 08 requires revising the RFM to reflect the reduced altitude operating limitations for Jet B and JP–4 wide-cut fuels. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM 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. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. Related Service Information Under 1 CFR Part 51 The FAA reviewed Figure 1–6. Fuel Operating Envelope (Sheet 1 of 1) of Bell 505 Rotorcraft Flight Manual BHT– 505–FM–1, Revision 3, dated July 25, 2018, which specifies limitations, normal and emergency procedures, performance data, weight and balance information, and provides a list of approved optional equipment supplements. This revision of the service information includes an updated figure of the fuel operating envelope showing the reduced pressure altitude limitations for Jet B and JP–4 fuels. 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 the ADDRESSES section. Differences Between This AD and the Transport Canada AD Canadian AD CF–2019–08 requires updating the RFM to Bell 505 RFM BHT–505–FM–1 Revision 3 or later revisions approved by Transport Canada, whereas this AD requires revising the Limitations Section of the RFM for your helicopter by replacing the existing Figure 1–6. with Figure 1– 6. Fuel Operating Envelope (Sheet 1 of PO 00000 Frm 00023 Fmt 4700 Sfmt 4700 69999 1) of Bell 505 RFM BHT–505–FM–1, Revision 3, dated July 25, 2018. Costs of Compliance The FAA estimates that this AD affects 73 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. Revising the existing RFM for your helicopter would take about 0.5 workhour for an estimated cost of $43 per helicopter or $3,139 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 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.

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 Bell Textron 
Canada Limited (type certificate previously held by Bell Helicopter 
Textron Canada Limited) Model 505 helicopters. The NPRM published in 
the Federal Register on September 20, 2021 (86 FR 52109). In the NPRM, 
the FAA proposed to require revising the existing RFM for your 
helicopter. Incorporating the RFM revision may be performed by the 
owner/operator (pilot) holding at least a private pilot certificate and 
must be entered into the aircraft records showing compliance with this 
AD in accordance with 14 CFR 43.9(a)(1) through (4) and 14 CFR 
91.417(a)(2)(v). The record must be maintained as required by 14 CFR 
91.417, 121.380, or 135.439. This is an exception to the FAA's standard 
maintenance regulations.
    The NPRM was prompted by Canadian AD CF-2019-08, dated March 5, 
2019 (Canadian AD CF-2019-08), issued by Transport Canada, which is the 
aviation authority for Canada, to correct an unsafe condition for Bell 
Helicopter Textron Canada Limited Model 505 helicopters serial numbers 
65011 and subsequent. Transport Canada advises of the need to reduce 
the altitude limitations for Jet B and JP-4 wide-cut fuels following 
unsatisfactory performance of the engine at the original higher 
altitude limitations with these wide-cut fuels. This condition, if not 
addressed, could result in low fuel pressure, engine flame-out, or 
engine power interruption (a change in any engine performance 
parameter--including but not limited to gas generator speed, power 
turbine speed, main gas temperature, or output torque--outside its 
normal limits for the prevailing operating conditions).
    Accordingly, Canadian AD CF-2019-08 requires revising the RFM to 
reflect the reduced altitude operating limitations for Jet B and JP-4 
wide-cut fuels.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM 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. Except for minor editorial changes, this AD is adopted as 
proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Figure 1-6. Fuel Operating Envelope (Sheet 1 of 1) 
of Bell 505 Rotorcraft Flight Manual BHT-505-FM-1, Revision 3, dated 
July 25, 2018, which specifies limitations, normal and emergency 
procedures, performance data, weight and balance information, and 
provides a list of approved optional equipment supplements. This 
revision of the service information includes an updated figure of the 
fuel operating envelope showing the reduced pressure altitude 
limitations for Jet B and JP-4 fuels.
    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 the ADDRESSES section.

Differences Between This AD and the Transport Canada AD

    Canadian AD CF-2019-08 requires updating the RFM to Bell 505 RFM 
BHT-505-FM-1 Revision 3 or later revisions approved by Transport 
Canada, whereas this AD requires revising the Limitations Section of 
the RFM for your helicopter by replacing the existing Figure 1-6. with 
Figure 1-6. Fuel Operating Envelope (Sheet 1 of 1) of Bell 505 RFM BHT-
505-FM-1, Revision 3, dated July 25, 2018.

Costs of Compliance

    The FAA estimates that this AD affects 73 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.
    Revising the existing RFM for your helicopter would take about 0.5 
work-hour for an estimated cost of $43 per helicopter or $3,139 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 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.

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

2021-24-04 Bell Textron Canada Limited (Type Certificate Previously 
Held by Bell Helicopter Textron Canada Limited): Amendment 39-21825; 
Docket No. FAA-2021-0783; Project Identifier 2019-SW-009-AD.

(a) Effective Date

    This airworthiness directive (AD) is effective January 13, 2022.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bell Helicopter Textron Canada Limited (type 
certificate previously held by Bell Helicopter Textron Canada

subsequent, certificated in any category.

(d) Subject

    Joint Aircraft Service Component (JASC) Code: 7300, Engine fuel 
and control.

(e) Unsafe Condition

    This AD was prompted by the determination that reducing the 
pressure altitude limitations for certain fuel types is necessary. 
The FAA is issuing this AD to address unsatisfactory flight 
performance of the engine above pressure altitude limitations for 
Jet B and JP-4 fuels. The unsafe condition, if not addressed, could 
result in low fuel pressure, engine flame-out, or engine power 
interruption.

(f) Compliance

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

(g) Required Actions

    Within 30 calendar days after the effective date of this AD,

information identical to that in Figure 1-6. Fuel Operating Envelope 
(Sheet 1 of 1) of BHT-505-FM-1 Revision 3 is acceptable for 
compliance with the requirements of this AD. The action required by 
this paragraph may be performed by the owner/operator (pilot) 
holding at least a private pilot certificate and must be entered
