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 PO 00000 Frm 00021 Fmt 4700 Sfmt 4700 40937 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.

SUPPLEMENTARY INFORMATION: I. Background The Fair Labor Standards Act (FLSA or Act) requires all covered employers to pay nonexempt employees at least the Federal minimum wage for every hour worked in a non-overtime workweek.1 In an overtime workweek, for all hours worked in excess of 40 in a workweek, covered employers must pay a nonexempt employee at least one and one-half times the employee’s regular rate.2 The FLSA also requires covered employers to make, keep, and preserve certain records regarding employees.3 The FLSA does not define ‘‘joint employer’’ or ‘‘joint employment.’’ However, section 3(d) of the Act defines ‘‘employer’’ to ‘‘include[ ] any person acting directly or indirectly in the interest of an employer in relation to an employee.’’ 4 Section 3(e) generally defines ‘‘employee’’ to mean ‘‘any individual employed by an employer’’ 5 and identifies certain specific groups of workers who are not ‘‘employees’’ for purposes of the Act.6 Section 3(g) defines ‘‘employ’’ to ‘‘include[ ] to suffer or permit to work.’’ 7 A.

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

    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.

Bombardier, Inc.): Amendment 39-21616; Docket No. FAA-2021-0264; 
Project Identifier MCAI-2020-01416-T.

(a) Effective Date

    This airworthiness directive (AD) is effective September 3, 
2021.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to MHI RJ Aviation ULC (type certificate 
previously held by Bombardier, Inc.) Model CL-600-2D15 (Regional Jet 
Series 705) and CL-600-2D24 (Regional Jet Series 900) airplanes, 
certificated in any category, having serial numbers 15057, 15063

(d) Subject

    Air Transport Association (ATA) of America Code 53, Fuselage.

(e) Unsafe Condition

    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. 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.

unless already done.

(g) Required Actions

    Within 36 months after the effective date of this AD: Modify the
