SUPPLEMENTARY INFORMATION:
Background
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued TCCA AD CF-2016-37, dated November 25,
2016 (also referred to as the Mandatory Continuing Airworthiness
Information, or the MCAI), to correct an unsafe condition for all
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 <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. FAA-2020-
1181.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all 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 17, 2021 (86 FR 14551). The NPRM was prompted by
reports of corrosion on the passenger door internal structure of in-
service airplanes caused by an accumulation of moisture under the epoxy
ramp. The NPRM proposed to require revising the existing maintenance or
inspection program, as applicable, to incorporate new or more
restrictive airworthiness limitations. The FAA is issuing this AD to
address corrosion on the passenger door internal structure and
consequent loss of the structural integrity of the forward passenger
door. See the MCAI for additional background information.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The FAA received no comments on the NPRM or
on the determination of the cost to the public.
Conclusion
The FAA reviewed the relevant data 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:
<bullet> Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
The FAA reviewed the following Bombardier service information,
which describes new or more restrictive airworthiness limitations for
the upper latch pins of the forward passenger door. These documents are
distinct since they apply to different airplane configurations. (Note:
The asterisk (or ``one star'') with the last three digits of the task
number indicates that the task is an airworthiness limitation task.)
<bullet> Task 53-10-01-101 *, ``Upper Latch Pins of the Passenger
Door,'' of Bombardier Challenger CL-600-1A11 Time Limits/Maintenance
Checks (TLMC), Product Support Publication (PSP) 605, Revision 39,
dated January 8, 2018.
<bullet> Task 53-10-01-101 *, ``Upper Latch Pins of the Passenger
Door,'' of Bombardier Challenger CL-600-2A12 TLMC, PSP 601-5, Revision
46, dated January 8, 2018.
<bullet> Task 53-10-01-101 *, ``Upper Latch Pins of the Passenger
Door,'' of Bombardier Challenger CL-600-2B16 TLMC, PSP 601A-5, Revision
42, dated January 8, 2018.
<bullet> Task 53-20-00-188 *, ``Special Detailed Inspection of the
Upper Latch Pins of the Passenger Door,'' of Bombardier Challenger
TLMC, CH 604 TLMC, Revision 32, dated December 18, 2019.
<bullet> Task 53-20-00-188 *, ``Special Detailed Inspection of the
Upper Latch Pins of the Passenger Door,'' of Bombardier Challenger
TLMC, CH 605 TLMC, Revision 21, dated December 18, 2019.
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 133 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
The FAA has determined that revising the maintenance or inspection
program takes an average of 90 work-hours per operator, although the
agency recognizes that this number may vary from operator to operator.
Since
[[Page 42702]]
operators incorporate maintenance or inspection program changes for
their affected fleet(s), the FAA has determined that a per-operator
estimate is more accurate than a per-airplane estimate. Therefore, the
agency estimates the average total cost per operator to be $7,650 (90
work-hours x $85 per work-hour).
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.
