SUPPLEMENTARY INFORMATION:
Discussion
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian AD
CF–2020–09, dated April 7, 2020 (also
referred to as the Mandatory Continuing
Airworthiness Information, or the
MCAI), to correct an unsafe condition
for certain MHI RJ Aviation ULC Model
CL–600–2B19 (Regional Jet Series 100 &
440) 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–2020–0691.
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain MHI RJ Aviation ULC
Model CL–600–2B19 (Regional Jet
Series 100 & 440) airplanes. The NPRM
published in the Federal Register on
October 5, 2020 (85 FR 62626). The
NPRM was prompted by evidence that
a revised structural life limit of some
components of the NLG and/or MLG
was not implemented during repair. The
NPRM proposed to require verifying
that the affected components are
installed on the airplane, revising the
structural life limits in the existing SDIR
airplane document, and replacing
affected components if necessary. The
FAA is issuing this AD to address
structural life limits that are lower than
the life limit published in the
Maintenance Requirements Manual
(MRM), Part 2. This condition, if not
corrected, could lead to the collapse of
the affected NLG and/or MLG, possibly
resulting in airplane damage and injury
to the occupants. See the MCAI for
additional background information.
Comments
The FAA gave the public the
opportunity to participate in developing
this final rule. The FAA has considered
the comment received. Air Line Pilots
Association, International (ALPA) stated
that it supports the NPRM.
Additional Change Made to This AD
This AD has been revised to provide
the revised structural life limits in figure
1 to paragraph (h) of this AD instead of
referencing the individual repair
engineering orders (REOs) in paragraph
(h) of this AD. The REOs did not meet
the Office of the Federal Register’s
criteria for incorporation by reference.
Conclusion
The FAA reviewed the relevant data,
considered the comment received, and
determined that air safety and the
public interest require adopting this
final rule with the changes described
previously and 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.
The FAA also determined that these
changes will not increase the economic
burden on any operator or increase the
scope of this final rule.
Related Service Information Under 1
CFR Part 51
Bombardier has issued Service
Bulletin 601R–32–112, dated November
11, 2019. This service information
describes procedures for verifying that
affected components are installed on the
airplane, revising the structural life
limits in the existing SDIR airplane
document, and replacing affected parts
if necessary. 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.

SUPPLEMENTARY INFORMATION:
Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2020-09, dated April 7,
2020 (also referred to as the Mandatory Continuing Airworthiness
Information, or the MCAI), to correct an unsafe condition for certain
MHI RJ Aviation ULC Model CL-600-2B19 (Regional Jet Series 100 & 440)
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-2020-0691.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain MHI RJ Aviation
ULC Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. The
NPRM published in the Federal Register on October 5, 2020 (85 FR
62626). The NPRM was prompted by evidence that a revised structural
life limit of some components of the NLG and/or MLG was not implemented
during repair. The NPRM proposed to require verifying that the affected
components are installed on the airplane, revising the structural life
limits in the existing SDIR airplane document, and replacing affected
components if necessary. The FAA is issuing this AD to address
structural life limits that are lower than the life limit published in
the Maintenance Requirements Manual (MRM), Part 2. This condition, if
not corrected, could lead to the collapse of the affected NLG and/or
MLG, possibly resulting in airplane damage and injury to the occupants.
See the MCAI for additional background information.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The FAA has considered the comment
received. Air Line Pilots Association, International (ALPA) stated that
it supports the NPRM.
Additional Change Made to This AD
This AD has been revised to provide the revised structural life
limits in figure 1 to paragraph (h) of this AD instead of referencing
the individual repair engineering orders (REOs) in paragraph (h) of
this AD. The REOs did not meet the Office of the Federal Register's
criteria for incorporation by reference.
Conclusion
The FAA reviewed the relevant data, considered the comment
received, and determined that air safety and the public interest
require adopting this final rule with the changes described previously
and 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.
The FAA also determined that these changes will not increase the
economic burden on any operator or increase the scope of this final
rule.
Related Service Information Under 1 CFR Part 51
Bombardier has issued Service Bulletin 601R-32-112, dated November
11, 2019. This service information describes procedures for verifying
that affected components are installed on the airplane, revising the
structural life limits in the existing SDIR airplane document, and
replacing affected parts if necessary. 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.
Costs of Compliance
The FAA estimates that this AD affects 456 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 143 work-hours x $85 per Up to $103,114............ Up to $115,269........... Up to $52,562,664.
hour = Up to $12,155.
----------------------------------------------------------------------------------------------------------------
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
[[Page 10755]]
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.
List of Subjects in 14 CFR Part 39
