SUPPLEMENTARY INFORMATION:
lotter on DSK11XQN23PROD with RULES1
Background
EASA, which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD 2020–0211,
dated October 5, 2020 (EASA AD 2020–
0211); and EASA AD 2021–0026, dated
January 20, 2021 (EASA AD 2021–
0026); (also referred to as the Mandatory
Continuing Airworthiness Information,
or the MCAI) to correct an unsafe
condition for all Airbus SAS Model
A350–941 and –1041 airplanes. EASA
AD 2021–0026 refers to Airbus A350
Airworthiness Limitations Section
(ALS) Part 4, Variation 5.1, dated July
22, 2020. Airplanes with an original
airworthiness certificate or original
VerDate Sep<11>2014
16:28 Jul 29, 2021
Jkt 253001
export certificate of airworthiness
issued after July 22, 2020, must comply
with the airworthiness limitations
specified as part of the approved type
design and referenced on the type
certificate data sheet; this AD therefore
does not include those airplanes in the
applicability.
The FAA issued AD 2019–20–01,
Amendment 39–19754 (84 FR 55495,
October 17, 2019) (AD 2019–20–01), to
require, among other things, repetitive
greasing of certain thrust reverser
actuators (TRAs). For those TRAs
identified as batch 02 in EASA AD
2018–0234R2, dated September 17, 2019
(which is required by AD 2019–20–01),
the repetitive greasing task has since
been incorporated into Airbus A350
Airworthiness Limitations Section
(ALS), Part 4, Systems Equipment
Maintenance Requirements (SEMR),
Revision 05 Issue 02, dated June 25,
2020, which is specified in EASA 2020–
0211. Accomplishing the actions in this
AD would therefore terminate the
repetitive greasing of batch 02 TRAs
required by paragraph (g) of AD 2019–
20–01.
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain Airbus SAS Model
A350–941 and –1041 airplanes. The
NPRM published in the Federal
Register on April 16, 2021 (86 FR
20086). The NPRM was prompted by a
determination that new or more
restrictive airworthiness limitations are
necessary. The NPRM proposed to
require revising the existing
maintenance or inspection program, as
specified in EASA AD 2020–0211 and
EASA AD 2021–0026.
The FAA is issuing this AD to address
hazardous or catastrophic airplane
system failures. 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)
stated 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
PO 00000
Frm 00019
Fmt 4700
Sfmt 4700

• Do not add any additional burden
upon the public than was already
proposed in the NPRM.
Related Service Information Under 1
CFR Part 51
EASA AD 2020–0211 and EASA AD
2021–0026 describe new or more
restrictive airworthiness limitations for
airplane systems and safe life limits.
These documents are distinct because
they apply to different airplane
configurations. This material 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 15 airplanes of U.S. registry. The
FAA estimates the following costs to
comply with this AD:
The FAA has determined that revising
the existing maintenance or inspection
program takes an average of 90 workhours per operator, although the agency
recognizes that this number may vary
from operator to operator. Since
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 ×
$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

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

EASA AD 2021–0026, dated January 20, 2021
(EASA AD 2021–0026). Where EASA AD
2021–0026 affects the same airworthiness
limitations (tasks and life limits) as those in
EASA AD 2020–0211, the airworthiness
limitations referenced in EASA AD 2021–
0026 prevail.
List of Subjects in 14 CFR Part 39
(h) Exceptions to EASA AD 2020–0211 and
EASA AD 2021–0026
(1) Where EASA AD 2020–0211 and EASA
AD 2021–0026 refers to its effective date, this

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

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.

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Airbus SAS Model A350-941 and -1041 airplanes. This AD was
prompted by a determination that new or more restrictive airworthiness
limitations are necessary. This AD requires revising the existing
maintenance or inspection program, as applicable, to incorporate new or
more restrictive airworthiness limitations, as specified in two
European Union Aviation Safety Agency (EASA) ADs, which are
incorporated by reference. The FAA is issuing this AD to address the
unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2020-0211, dated October 5, 2020
(EASA AD 2020-0211); and EASA AD 2021-0026, dated January 20, 2021
(EASA AD 2021-0026); (also referred to as the Mandatory Continuing
Airworthiness Information, or the MCAI) to correct an unsafe condition
for all Airbus SAS Model A350-941 and -1041 airplanes. EASA AD 2021-
0026 refers to Airbus A350 Airworthiness Limitations Section (ALS) Part
4, Variation 5.1, dated July 22, 2020. Airplanes with an original
airworthiness certificate or original export certificate of
airworthiness issued after July 22, 2020, must comply with the
airworthiness limitations specified as part of the approved type design
and referenced on the type certificate data sheet; this AD therefore
does not include those airplanes in the applicability.
The FAA issued AD 2019-20-01, Amendment 39-19754 (84 FR 55495,
October 17, 2019) (AD 2019-20-01), to require, among other things,
repetitive greasing of certain thrust reverser actuators (TRAs). For
those TRAs identified as batch 02 in EASA AD 2018-0234R2, dated
September 17, 2019 (which is required by AD 2019-20-01), the repetitive
greasing task has since been incorporated into Airbus A350
Airworthiness Limitations Section (ALS), Part 4, Systems Equipment
Maintenance Requirements (SEMR), Revision 05 Issue 02, dated June 25,
2020, which is specified in EASA 2020-0211. Accomplishing the actions
in this AD would therefore terminate the repetitive greasing of batch
02 TRAs required by paragraph (g) of AD 2019-20-01.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain Airbus SAS
Model A350-941 and -1041 airplanes. The NPRM published in the Federal
Register on April 16, 2021 (86 FR 20086). The NPRM was prompted by a
determination that new or more restrictive airworthiness limitations
are necessary. The NPRM proposed to require revising the existing
maintenance or inspection program, as specified in EASA AD 2020-0211
and EASA AD 2021-0026.
The FAA is issuing this AD to address hazardous or catastrophic
airplane system failures. 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) stated
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
EASA AD 2020-0211 and EASA AD 2021-0026 describe new or more
restrictive airworthiness limitations for airplane systems and safe
life limits. These documents are distinct because they apply to
different airplane configurations. This material 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 15 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
The FAA has determined that revising the existing 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 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
[[Page 40936]]
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.
