Airworthiness Directives; MHI RJ Aviation ULC (Type Certificate
Previously Held by Bombardier, Inc.) Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain MHI RJ Aviation ULC Model CL-600-2D15 (Regional Jet Series 705)
and CL-600-2D24 (Regional Jet Series 900) airplanes. This AD was
prompted by a report that the lower aft outboard supporting structure
of galley 2 does not meet certification requirements for all flight
and/or emergency landing loads. This AD requires modifying the floor
structure between certain fuselage stations. The FAA is issuing this AD
to address the unsafe condition on these products.
DATES: This AD is effective September 3, 2021.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of September 3,
2021.

SUPPLEMENTARY INFORMATION:
Background
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued TCCA AD CF-2020-40, dated October 15,
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-600-2D15 (Regional Jet Series 705) and CL-
600-2D24 (Regional Jet Series 900) 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-2021-0264.
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-600-2D15 (Regional Jet Series 705) and CL-600-2D24
(Regional Jet Series 900) airplanes. The NPRM published in the Federal
Register on April 7, 2021 (86 FR 17998). The NPRM was prompted by a
report that the lower aft outboard supporting structure of galley 2
does not meet certification requirements for all flight and/or
emergency landing loads. The NPRM proposed to require modifying the
floor structure between certain fuselage stations. The FAA is issuing
this AD to address the insufficient structural safety margin of galley
2 in case of hard landing or severe turbulence. This condition, if not
corrected, could result in injury to the occupants and could limit
access to the exit door during emergencies if the galley is displaced
or fails structurally. 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. The Air Line Pilots Association, International (ALPA),
indicated its support for the NPRM.
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 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.
Related Service Information Under 1 CFR Part 51
MHI RJ has issued MHI RJ Service Bulletin 670BA-53-060, Revision A,
dated September 17, 2020. This service information describes procedures
for modifying the floor structure between fuselage station (FS) 379.00
and FS 394.00 at right buttock line (RBL) 37.75. 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 1 airplane of U.S. registry.
The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
20 work-hours x $85 per hour = $1,700........................ $5,081 $6,781 $6,781

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.
