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.

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.
