SUPPLEMENTARY INFORMATION:
Background
EASA, which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD 2020–0219,
dated October 12, 2020 (EASA AD
2020–0219) (also referred to as the
mandatory continuing airworthiness
information, or ‘‘the MCAI’’), to correct
an unsafe condition for all Airbus SAS
Model A318 series; Model A319–111,
–112, –113, –114, –115, –131, –132,
–133, –151N, and –153N; Model A320–
211, –212, –214, –215, –216, –231, –232,
–233, –251N, –252N, –253N, –271N,
–272N, and –273N airplanes; and Model
A321 series airplanes. Model A320–215
airplanes are not certificated by the FAA
and are not included on the U.S. type
certificate data sheet; this AD therefore
does not include those airplanes in the
applicability.
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
A318 series; Model A319–111, –112,
–113, –114, –115, –131, –132, –133,
–151N, and –153N; Model A320 series
airplanes; and Model A321 series
airplanes. The NPRM published in the
Federal Register on March 26, 2021 (86
E:\FR\FM\24AUR1.SGM
24AUR1
Federal Register / Vol. 86, No. 161 / Tuesday, August 24, 2021 / Rules and Regulations
FR 16130). The NPRM was prompted by
a determination that the new and more
restrictive airworthiness limitations are
necessary The NPRM proposed to
require revising the existing
maintenance or inspection program, as
applicable, to incorporate new or more
restrictive airworthiness limitations, as
specified in EASA AD 2020–0219.
The FAA is issuing this AD to address
a safety-significant latent failure (that is
not annunciated), which, in
combination with one or more other
specific failures or events, could result
in a hazardous or catastrophic failure
condition. See the MCAI for additional
background information.
Comments
The FAA gave the public the
opportunity to participate in developing
this final rule. The following presents
the comments received on the NPRM
and the FAA’s response to each
comment.
Support for the NPRM
The Air Line Pilots Association,
International (ALPA) supported the
NPRM.

Request To Clarify the Need for
Paragraph (i) of the Proposed AD
Delta Air Lines (Delta) requested
clarification on the need for paragraph
(i) of the proposed AD. The commenter
asked whether the paragraph was
necessary since paragraph (k) of FAA
AD 2020–22–16, Amendment 39–21312
(85 FR 70439, November 5, 2020) (AD
2020–22–16) allows the use of
alternative actions/intervals if they are
later-approved variations or revisions of
Airbus A318/A319/A320/A321
Airworthiness Limitation Section (ALS)
Part 3 Certification Maintenance
Requirements (CMR) Revision 07 Issue
02, dated January 17, 2020, as specified
in EASA AD 2020–0067, dated April 6,
2020.
The FAA does not agree that
paragraph (k) of AD 2020–22–16 makes
paragraph (i) of this AD unnecessary.
The intent of paragraph (i) of this AD is
to clarify that the termination action is
for specific tasks in ALS Part 3 Variation
7.1 that were also required in
accordance with AD 2020–22–16, not
the entire ALS Part 3 document.
Although operators are allowed to
comply with later revisions of that
document, they are not required to do
so unless the FAA issues an AD
requiring the incorporation of that later
revision. Therefore, without the older
versions of these tasks being terminated,
operators would have to show
compliance with both versions of these
VerDate Sep<11>2014

Jkt 253001
tasks. No change has been made to this
AD.
Request To Clarify the Meaning of
Paragraph (h) of the Proposed AD
Delta requested clarification about its
understanding of paragraph (h) of the
proposed AD. The commenter said it
interpreted ‘‘later approved revisions of
this document’’ to mean later approved
variations of ALS Part 3, e.g., Variation
7.2, 7.3, etc.
The FAA agrees with Delta’s
interpretation of paragraph (h) of this
AD.
Request To Reduce the Number of ADs
Required for Compliance
Delta expressed concern that multiple
ADs would be required for compliance
with ALS Part 3. The commenter noted
that EASA AD 2021–0108, dated April
20, 2021, was recently issued and
requires incorporating Airbus A318/
A319/A320/A321 Airworthiness
Limitations Section (ALS) Part 3
Variation 7.3. Delta stated that after the
FAA AD associated with EASA AD
2021–0108 is published, operators will
be required to show compliance with
three ADs related to Airbus A318/A319/
A320/A321 ALS Part 3 instead of the
usual one. The FAA infers a request by
Delta to reduce the number of ADs.
The FAA disagrees with reducing the
number of ADs. While the FAA
acknowledges that operators need to
manage multiple ADs for compliance
with ALS Part 3 (CMR), the FAA notes
that two of the three EASA ADs require
incorporating variations, rather than full
revisions of Airbus A318/A319/A320/
A321 ALS Part 3. Superseding AD
2020–22–16 would remove the
requirement to show compliance with
the full revision of the ALS document,
potentially introducing an unsafe
condition. In addition, the FAA notes
that incorporation of the variations is
necessary to mitigate an unsafe
condition. Therefore, no change has
been made to this AD.
Conclusion
The FAA reviewed the relevant data,
considered the comments 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 2020–0219 specifies new
and more restrictive airworthiness
limitations for certain safety valves.
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 will
affect 1,680 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. 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 would be $7,650 (90 workhours × $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:

SUPPLEMENTARY INFORMATION:
Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2020-0219, dated October 12, 2020
(EASA AD 2020-0219) (also referred to as the mandatory continuing
airworthiness information, or ``the MCAI''), to correct an unsafe
condition for all Airbus SAS Model A318 series; Model A319-111, -112, -
113, -114, -115, -131, -132, -133, -151N, and -153N; Model A320-211, -
212, -214, -215, -216, -231, -232, -233, -251N, -252N, -253N, -271N, -
272N, and -273N airplanes; and Model A321 series airplanes. Model A320-
215 airplanes are not certificated by the FAA and are not included on
the U.S. type certificate data sheet; this AD therefore does not
include those airplanes in the applicability.
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 A318 series; Model A319-111, -112, -113, -114, -115, -131, -132,
-133, -151N, and -153N; Model A320 series airplanes; and Model A321
series airplanes. The NPRM published in the Federal Register on March
26, 2021 (86
[[Page 47213]]
FR 16130). The NPRM was prompted by a determination that the new and
more restrictive airworthiness limitations are necessary The NPRM
proposed to require revising the existing maintenance or inspection
program, as applicable, to incorporate new or more restrictive
airworthiness limitations, as specified in EASA AD 2020-0219.
The FAA is issuing this AD to address a safety-significant latent
failure (that is not annunciated), which, in combination with one or
more other specific failures or events, could result in a hazardous or
catastrophic failure condition. See the MCAI for additional background
information.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The following presents the comments
received on the NPRM and the FAA's response to each comment.
Support for the NPRM
The Air Line Pilots Association, International (ALPA) supported the
NPRM.
Request To Clarify the Need for Paragraph (i) of the Proposed AD
Delta Air Lines (Delta) requested clarification on the need for
paragraph (i) of the proposed AD. The commenter asked whether the
paragraph was necessary since paragraph (k) of FAA AD 2020-22-16,
Amendment 39-21312 (85 FR 70439, November 5, 2020) (AD 2020-22-16)
allows the use of alternative actions/intervals if they are later-
approved variations or revisions of Airbus A318/A319/A320/A321
Airworthiness Limitation Section (ALS) Part 3 Certification Maintenance
Requirements (CMR) Revision 07 Issue 02, dated January 17, 2020, as
specified in EASA AD 2020-0067, dated April 6, 2020.
The FAA does not agree that paragraph (k) of AD 2020-22-16 makes
paragraph (i) of this AD unnecessary. The intent of paragraph (i) of
this AD is to clarify that the termination action is for specific tasks
in ALS Part 3 Variation 7.1 that were also required in accordance with
AD 2020-22-16, not the entire ALS Part 3 document. Although operators
are allowed to comply with later revisions of that document, they are
not required to do so unless the FAA issues an AD requiring the
incorporation of that later revision. Therefore, without the older
versions of these tasks being terminated, operators would have to show
compliance with both versions of these tasks. No change has been made
to this AD.
Request To Clarify the Meaning of Paragraph (h) of the Proposed AD
Delta requested clarification about its understanding of paragraph
(h) of the proposed AD. The commenter said it interpreted ``later
approved revisions of this document'' to mean later approved variations
of ALS Part 3, e.g., Variation 7.2, 7.3, etc.
The FAA agrees with Delta's interpretation of paragraph (h) of this
AD.
Request To Reduce the Number of ADs Required for Compliance
Delta expressed concern that multiple ADs would be required for
compliance with ALS Part 3. The commenter noted that EASA AD 2021-0108,
dated April 20, 2021, was recently issued and requires incorporating
Airbus A318/A319/A320/A321 Airworthiness Limitations Section (ALS) Part
3 Variation 7.3. Delta stated that after the FAA AD associated with
EASA AD 2021-0108 is published, operators will be required to show
compliance with three ADs related to Airbus A318/A319/A320/A321 ALS
Part 3 instead of the usual one. The FAA infers a request by Delta to
reduce the number of ADs.
The FAA disagrees with reducing the number of ADs. While the FAA
acknowledges that operators need to manage multiple ADs for compliance
with ALS Part 3 (CMR), the FAA notes that two of the three EASA ADs
require incorporating variations, rather than full revisions of Airbus
A318/A319/A320/A321 ALS Part 3. Superseding AD 2020-22-16 would remove
the requirement to show compliance with the full revision of the ALS
document, potentially introducing an unsafe condition. In addition, the
FAA notes that incorporation of the variations is necessary to mitigate
an unsafe condition. Therefore, no change has been made to this AD.
Conclusion
The FAA reviewed the relevant data, considered the comments
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 2020-0219 specifies new and more restrictive airworthiness
limitations for certain safety valves. 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 will affect 1,680 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. 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 would 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:
[[Page 47214]]
(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.
