50237
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to Bell Textron Canada Limited
Model 505 helicopters, with serial
numbers 65011 through 65023
inclusive, 65025 through 65028
inclusive, 65030 through 65032
inclusive, 65034, and 65036 with relay
panel assembly part number (P/N) SLS–
075–002–107 installed. The NPRM
published in the Federal Register on
May 25, 2021 (86 FR 28038). In the
NPRM, the FAA proposed to require
replacing relay panel assembly part
number P/N SLS–075–002–107 with
relay panel assembly P/N SLS–075–
002–109. The NPRM also proposed to
prohibit installing relay panel assembly
P/N SLS–075–002–107 on any
helicopter. The NPRM was prompted by
Canadian AD CF–2017–36, dated
December 15, 2017 (Canadian AD CF–
2017–36), issued by Transport Canada,
which is the aviation authority for
Canada, to correct an unsafe condition
for Bell Helicopter Textron Canada
Limited (BHTCL) (now Bell Textron
Canada Limited) Model 505 helicopters
serial numbers 65011 through 65023,
65025 through 65028, 65030 through
65032, 65034, and 65036. Transport
Canada advises of three occurrences of
metallic debris in the engine oil
lubrication system of the Model 505
helicopter causing the Garmin Engine
Airframe (GEA) 12 VDC reference
voltage to be shorted to ground. This
short to ground results in loss of display
of important flight information
including the main rotor rotations per
minute (Nr), fuel quantity, and
transmission oil pressure and
temperature, and the generator voltage
and ammeter parameters are marked
invalid with a red ‘‘X’’ on the primary
flight display (PFD) and the multifunction display (MFD). This condition,
if not addressed, could result in loss of
caution, advisory, and system
performance indications for multiple
helicopter systems, particularly when
E:\FR\FM\08SER1.SGM

Federal Register / Vol. 86, No. 171 / Wednesday, September 8, 2021 / Rules and Regulations
the initiating event may be the
activation of the engine chip detector.
Accordingly, Canadian AD CF–2017–
36 requires replacing relay panel
assembly P/N SLS–075–002–107 with
relay panel assembly P/N SLS–075–
002–109.
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 and
updating the email and website
addresses for Bell Textron Canada
Limited throughout this document, this
AD is adopted as proposed in the
NPRM.

Related Service Information Under 1
CFR Part 51
The FAA reviewed Bell Helicopter
Alert Service Bulletin 505–17–04, dated
December 6, 2017 (ASB 505–17–04).
ASB 505–17–04 specifies procedures for
replacing relay panel assembly P/N
SLS–075–002–107 with relay panel
assembly P/N SLS–075–002–109. ASB
505–17–04 also specifies procedures for
accomplishing a functional test of the
two engine electrical magnetic plugs
and provides a notice to ensure 505–
FM–1 (TR–2) is inserted into the flight
manual.
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–2017–36 requires
replacing the relay panel assembly
within 25 hours air time or 30 days,
whichever occurs first, whereas this AD
requires that replacement within 25
hours time-in-service instead. Canadian
AD CF–2017–36 applies to certain
serial-numbered Model 505 helicopters,
whereas this AD applies to certain
serial-numbered Model 505 helicopters

Jkt 253001
with relay panel assembly P/N SLS–
075–002–107 installed instead.
Costs of Compliance
The FAA estimates that this AD
affects 3 helicopters of U.S. Registry.
The FAA estimates that operators may
incur the following costs in order to
comply with this AD. Labor costs are
estimated at $85 per work-hour.
Replacing each relay panel assembly
takes about 3 work-hours and parts cost
$7,079 for an estimated cost of $7,334
per helicopter and $22,002 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 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.

inclusive, 65034, and 65036 with relay panel assembly part number (P/N)
SLS-075-002-107 installed. The NPRM published in the Federal Register
on May 25, 2021 (86 FR 28038). In the NPRM, the FAA proposed to require
replacing relay panel assembly part number P/N SLS-075-002-107 with
relay panel assembly P/N SLS-075-002-109. The NPRM also proposed to
prohibit installing relay panel assembly P/N SLS-075-002-107 on any
helicopter. The NPRM was prompted by Canadian AD CF-2017-36, dated
December 15, 2017 (Canadian AD CF-2017-36), issued by Transport Canada,
which is the aviation authority for Canada, to correct an unsafe
condition for Bell Helicopter Textron Canada Limited (BHTCL) (now Bell
Textron Canada Limited) Model 505 helicopters serial numbers 65011
through 65023, 65025 through 65028, 65030 through 65032, 65034, and
65036. Transport Canada advises of three occurrences of metallic debris
in the engine oil lubrication system of the Model 505 helicopter
causing the Garmin Engine Airframe (GEA) 12 VDC reference voltage to be
shorted to ground. This short to ground results in loss of display of
important flight information including the main rotor rotations per
minute (Nr), fuel quantity, and transmission oil pressure and
temperature, and the generator voltage and ammeter parameters are
marked invalid with a red ``X'' on the primary flight display (PFD) and
the multi-function display (MFD). This condition, if not addressed,
could result in loss of caution, advisory, and system performance
indications for multiple helicopter systems, particularly when
[[Page 50238]]
the initiating event may be the activation of the engine chip detector.
Accordingly, Canadian AD CF-2017-36 requires replacing relay panel
assembly P/N SLS-075-002-107 with relay panel assembly P/N SLS-075-002-
109.
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 and updating the email
and website addresses for Bell Textron Canada Limited throughout this
document, this AD is adopted as proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Bell Helicopter Alert Service Bulletin 505-17-04,
dated December 6, 2017 (ASB 505-17-04). ASB 505-17-04 specifies
procedures for replacing relay panel assembly P/N SLS-075-002-107 with
relay panel assembly P/N SLS-075-002-109. ASB 505-17-04 also specifies
procedures for accomplishing a functional test of the two engine
electrical magnetic plugs and provides a notice to ensure 505-FM-1 (TR-
2) is inserted into the flight manual.
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-2017-36 requires replacing the relay panel assembly
within 25 hours air time or 30 days, whichever occurs first, whereas
this AD requires that replacement within 25 hours time-in-service
instead. Canadian AD CF-2017-36 applies to certain serial-numbered
Model 505 helicopters, whereas this AD applies to certain serial-
numbered Model 505 helicopters with relay panel assembly P/N SLS-075-
002-107 installed instead.
Costs of Compliance
The FAA estimates that this AD affects 3 helicopters of U.S.
Registry. The FAA estimates that operators may incur the following
costs in order to comply with this AD. Labor costs are estimated at $85
per work-hour.
Replacing each relay panel assembly takes about 3 work-hours and
parts cost $7,079 for an estimated cost of $7,334 per helicopter and
$22,002 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 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.
