SUPPLEMENTARY INFORMATION:
Discussion
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian AD
CF–2019–26, dated July 9, 2019 (also
referred to as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for certain Bombardier, Inc., Model CL–
600–1A11 (600), CL–600–2A12 (601),
and CL–600–2B16 (601–3A, 601–3R,
and 604 Variants) airplanes. You may
examine the MCAI in the AD docket on
the internet at https://
www.regulations.gov by searching for
and locating Docket No. FAA–2020–
0203.
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain Bombardier, Inc., Model
CL–600–1A11 (600), CL–600–2A12
(601), and CL–600–2B16 (601–3A, 601–
3R, and 604 Variants) airplanes. The
NPRM published in the Federal
Register on March 23, 2020 (85 FR
16284). The NPRM was prompted by a
report that fast and easy access to the
portable oxygen bottle may be prevented
by the portable oxygen bottle
installation’s upper bracket latch
assembly catching on the pressure gauge
tube or on the pressure gauge bezel of
the portable oxygen bottle. The NPRM
proposed to require a check to identify
the manufacturer and part number of
the portable oxygen bottle installation,
and, if necessary, modification of the
portable oxygen bottle installation. The
FAA is issuing this AD to address the
portable oxygen bottle installation’s
upper bracket latch assembly catching
on the pressure gauge tube or on the
pressure gauge bezel of the portable
oxygen bottle, which, if not detected
and corrected, could prevent fast and
easy access to the portable oxygen bottle
in an emergency situation. See the
MCAI for additional background
information.
Comments
The FAA gave the public the
opportunity to participate in developing
this final rule. The following presents
the comment received on the NPRM and
the FAA’s response to each comment.
Support for the NPRM
An anonymous commenter had no
objection to the NPRM.
Request To Revise or Clarify the
Applicability of Paragraph (i) of the
Proposed AD
NetJets requested that the FAA either
revise the language in the first sentence
of paragraph (i) of the proposed AD to
clearly state that the paragraph applies
to airplanes having a serial number of
6119 and below that is not listed in
section 1.A. of the applicable
Bombardier service information
specified in figure 1 to paragraphs (g),
(h), and (i) of the proposed AD, or that
the FAA clarify paragraph (c)(3) of the
proposed AD to state that all serial
numbers are affected.
The FAA agrees to clarify. Paragraph
(i) of the proposed AD is applicable to
only airplanes having the serial
numbers specified in paragraph (c) of
this AD, but not listed in section 1.A. of
the applicable Bombardier service
information specified in figure 1 to
paragraphs (g), (h), and (i) of this AD,
and equipped with specified part
numbers of Scott (Avox/Zodiac) 5500 or
5600 series 11 cubic foot portable
oxygen bottle(s). As such, any serial
number not specified in paragraph (c)(3)
of this AD for Bombardier Inc. Model
CL–600–2B16 (601–3A, 601–3R, and
604 Variants) airplanes, is not affected
by paragraph (i) of this AD. The FAA
has not changed this AD in this regard.
Conclusion
The FAA reviewed the relevant data,
considered the comments received, and
determined that air safety and the
public interest require adopting this
final rule as proposed, except for minor
editorial changes. The FAA has
determined that these minor changes:
• Are consistent with the intent that
was proposed in the NPRM for
addressing the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.

Federal Register / Vol. 85, No. 189 / Tuesday, September 29, 2020 / Rules and Regulations
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.

SUPPLEMENTARY INFORMATION:
Background
The FAA was informed by the
manufacturer that a PGB development
test was stopped due to high vibration
caused by a fatigue crack that initiated
in the PGB shaft and carrier assembly.
The fatigue crack initiated in a broach
slot of the PGB shaft. The manufacturer
determined the need to apply life limits
to the PGB shaft and carrier assembly,
which has not previously been a lifelimited part. To track these parts, the
manufacturer determined the need to
assign usage hours to PGB shaft and
carrier assemblies that already have
time in service.
An examination by the manufacturer
of Material Review Board records also
identified two PGB shaft and carrier
assemblies that were accepted with
reduced material properties prior to
their reclassification as a life limited
part requiring reduced lives. The
manufacturer applied reduced life limits
to these PGB shaft and carrier
PO 00000
Frm 00009
Fmt 4700
Sfmt 4700

assemblies. In addition, a review of
shop repair records by the manufacturer
identified a number of PGB shaft and
carrier assemblies that received a
keylock stud repair introducing
unacceptable unused ‘‘keyslots’’ that
can cause stress concentration and
reduced life. The manufacturer requires
either rework or removal of these PGB
shaft and carrier assemblies.
The FAA determined that updating
the ALS of the RRC AE 2100D3
Maintenance Manual and the continued
airworthiness maintenance program for
the affected RRC 2100D3 model
turbofan engines is the most effective
way to address the unsafe condition
pertaining to fatigue cracks in the PGB
shaft and carrier assembly. These ALS
updates apply life limits to PGB shaft
and carrier assemblies installed on RRC
AE 2100D3 model turbofan engines.
Certain part numbered PGB shaft and
carrier assemblies with reduced material
properties were assigned reduced life
limits. To track these parts, the ALS
updates require assignment of usage
hours to the PGB shaft and carrier
assembly no later than the next engine
shop visit for all RRC AE model
turboprop engines. Depending on the
part and serial number of the PGB shaft
and carrier assembly, the updates to the
ALS requires reidentification or removal
of the PGB shaft and carrier assembly.
This condition, if not addressed,
could result in loss of the propeller,
damage to the engine, and damage to the
airplane. The FAA is issuing this AD to
address the unsafe condition on these
products.
FAA’s Determination
The FAA is issuing this AD because
the agency evaluated all the relevant
information and determined the unsafe
condition described previously is likely
to exist or develop in other products of
the same type design.

SUPPLEMENTARY INFORMATION:
Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2019-26, dated July 9,
2019 (also referred to as the Mandatory Continuing Airworthiness
Information, or ``the MCAI''), to correct an unsafe condition for
certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601),
and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. You may
examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-
0203.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain Bombardier,
Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-
3A, 601-3R, and 604 Variants) airplanes. The NPRM published in the
Federal Register on March 23, 2020 (85 FR 16284). The NPRM was prompted
by a report that fast and easy access to the portable oxygen bottle may
be prevented by the portable oxygen bottle installation's upper bracket
latch assembly catching on the pressure gauge tube or on the pressure
gauge bezel of the portable oxygen bottle. The NPRM proposed to require
a check to identify the manufacturer and part number of the portable
oxygen bottle installation, and, if necessary, modification of the
portable oxygen bottle installation. The FAA is issuing this AD to
address the portable oxygen bottle installation's upper bracket latch
assembly catching on the pressure gauge tube or on the pressure gauge
bezel of the portable oxygen bottle, which, if not detected and
corrected, could prevent fast and easy access to the portable oxygen
bottle in an emergency situation. See the MCAI for additional
background information.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The following presents the comment received
on the NPRM and the FAA's response to each comment.
Support for the NPRM
An anonymous commenter had no objection to the NPRM.
Request To Revise or Clarify the Applicability of Paragraph (i) of the
Proposed AD
NetJets requested that the FAA either revise the language in the
first sentence of paragraph (i) of the proposed AD to clearly state
that the paragraph applies to airplanes having a serial number of 6119
and below that is not listed in section 1.A. of the applicable
Bombardier service information specified in figure 1 to paragraphs (g),
(h), and (i) of the proposed AD, or that the FAA clarify paragraph
(c)(3) of the proposed AD to state that all serial numbers are
affected.
The FAA agrees to clarify. Paragraph (i) of the proposed AD is
applicable to only airplanes having the serial numbers specified in
paragraph (c) of this AD, but not listed in section 1.A. of the
applicable Bombardier service information specified in figure 1 to
paragraphs (g), (h), and (i) of this AD, and equipped with specified
part numbers of Scott (Avox/Zodiac) 5500 or 5600 series 11 cubic foot
portable oxygen bottle(s). As such, any serial number not specified in
paragraph (c)(3) of this AD for Bombardier Inc. Model CL-600-2B16 (601-
3A, 601-3R, and 604 Variants) airplanes, is not affected by paragraph
(i) of this AD. The FAA has not changed this AD in this regard.
Conclusion
The FAA reviewed the relevant data, considered the comments
received, and determined that air safety and the public interest
require adopting this final rule as proposed, except for minor
editorial changes. The FAA has determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
