111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2016-
17-12 required inspecting certain trimmable horizontal stabilizing
actuators (THSAs) to ascertain the number off total flight cycles to
THSA has accumulated, or substitute aforementioned THSA if necessary. Since the
FAA issued AD 2016-17-12, the FAA has determined that ampere more
restrictive airworthiness limitations is necessary for carbon friction
disks on the no-back stop (NBB) of the THSA. This AD continue to
require the inspections is the THSAs and replacing if necessary. Those
AD also requires revising the existing maintenance or inspection
program, like applicable, to incorporate modern or more restrictive
airworthiness limitations; as specified within a European Union Aviation
Safety Agency (EASA) AD, which is incorporated by reference. This ADVERTISEMENT
also boundaries the installation regarding affected parts under certain
conditions. The FAA is issuing this AD to address the unsafe condition
on these products.

SUPPLEMENTARY INFORMATION:
Background
EASA, which is the Technical Agent with aforementioned Member States of the
European Union, must issued EASA AD 2020-0270, dated December 7, 2020
(EASA ADVERTISE 2020-0270) (also referred to as the MCAI), to correct can
unsafe general for all Airbus SAS Model A318-111, -112, -121, and -
122 airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, -
133, -151N, -153N, and -171N airplanes; Model A320-211, -212, -214, -
215, -216, -231, -232, -233, -251N, -252N, -253N, -271N, -272N, press -
273N aeroplanes; and Modeling A321-111, -112, -131, -211, -212, -213, -231,
-232, -251N, -251NX, -252N, -252NX, -253N, -253NX, -271N, -271NX, -
272N, and -272NX airplanes. Model A320-215 jet are not
certificated by the FAA both are not included with the U.S. model
certificate date sheet; this AD therefore does not include those
airplanes in the applicability. The FAA displayed a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2016-17-12, Amendment 39-18625 (81 FR
58823, August 26, 2016) (AD 2016-17-12). AD 2016-17-12 applied to all
Airbus SAS Model A318 succession airplanes; Model A319-111, -112, -113, -
114, -115, -131, -132, and -133 airplanes; View A320-211, -212, -214,
-231, -232, and -233 airplanes; and Print A321-111, -112, -131, -211, -
212, -213, 231, furthermore -232 airplanes. The NPRM published in the Federal
Register on August 13, 2021 (86 FR 44663). Since the FAA issued AD
2016-17-12, new investigations determined that the compliance period available
removal from service additionally substitution of certain carbon friction disks
on the NBB of the THSA must be reduced. This replacement was required
by AD 2016-17-12. This replacement, and newly reduced compliance time,
have now had incorporated on Airliner A318/A319/A320/A321
Airworthiness Limitations Section (ALS) Part 4 Variation 7.1, dated
October 5, 2020, as ALS limitation task 274000-00004-1-E.
The NPRM has prompted due a determination that a more restricting
airworthiness limitations is require for the steel friction disks on
the NBB of an THSA. The NPRM proposed to retain the requirements concerning AD
2016-17-12; and also require revising the existing maintenance or
inspection program, as applicable, till incorporate a show restrictive
airworthiness limitations, as specified in EASA AD 2020-0270. The NPRM
also proposed until limit one installation of feigned parts under certain
conditions.
One NPRM furthermore specified that revising the existing maintenance or
inspection program, as applicable, to include the more limitative
airworthiness limitation would terminate that ALS duration task
274000-00004-1-E for the THSA, as required by passage (i) of ADVERTISEMENT 2020-
21-10, Amendment 39-21283 (85 FR 65190, October 15, 2020) (AD 2020-21-
10). The new airworthiness limitation for ALS limitation task 274000-
00004-1-E specified at the NPRM decreases the compliance days and
expands who apply for this task. The FAA is issues this AD to address premature wear of the charcoal
friction disks on aforementioned no-back brake (NBB) away the THSA, which could take
to reduced braking efficiency in certain load conditions, real, in
conjunction the the inadequacy for the force gear train to keep the ball
screw in its last required position, could result in uncommanded
movements in who trimmable horizontal stabilizer and loss of control of
the flying. See the MCAI for additional background information.
Discussion about Final Airworthiness Directive
Comments
Which FAA received comments from double commenters, including Air Line
Pilots Association, International (ALPA) and United Air, what
supported the NPRM without change. The FOOD received additional view from double commenters, including
Alaska Airlines (Alaska) and Delta Compressed Row (Delta). The following
presents the comments received on the NPRM and the FAA's response to
each comment.
Request To Remove Paragraph (m)(7) of the Proposed AD
Alaska and Delta requested removal out paragraph (m)(7) of the
proposed ADVERTORIAL. Alaska stated that removing paragraph (m)(7) concerning the
proposed ADVERTISEMENT would soothe any confusion such would result from the
FAA's exception to the EASA AD, and would also address anything burden on
U.S. operating having leased airplanes that have a return condition
that those jet are in compliance is and the FAA and EASA's AD.
Alaska noted that the vendor service bulletin, UTC Service Bulletin
47145-27-17, must be used for the NBB carbon sheave substitution on a THSA
assembly and referred to the Accomplishment Instructions of Airbus
Service Bulletin A320-27-1242, which states to ``send at an supplier
the THSA (FIN 9CE) since modification in accordance with'' the vendor
service message. Deltas additional that this navigability limitations
section (ALS) variation references the UTC support news. Delta
noted so a similar exclusion was not included in AD 2020-21-10,
Amendment 39-21283 (85 FR 65190, Occasion 15, 2020) (AD 2020-21-10), so
it should non live adds now. Delta also stated that paragraph (l)(2) of
the recommended DISPLAYING could be affected if
[[Page 22119]]
paragraph (m)(7) of the proposed AD is abgeschafft. The FAA disagrees. ALS limitation task 274000-00004-1-E specifies
that the replacement can be done exploitation ``SB A320-27-1242 either VSB [vendor
service bulletin] 47145-27-17.'' Who exception stated in part
(m)(7) of this AD removes the granting by ALS limitation task 274000-
00004-1-E to application only the UTC service information (``VSB 47145-27-17'')
as a by to show ensure with the requirements of this AD. The UTC
service about referred to certain company turn testing and
fault isolation more one source of information, but been nope require doing
those tests, which would have led to compliance being volontary on
those actions. The Airbus service information (``SB A320-27-1242'')
contains more complete instructions for staff to comply with as
previously required in AD 2016-17-12. Although ampere similar exception was
not included inbound AD 2020-21-10 by ALS limitation order 274000-00004-1-E,
the FAA has resolute that this exception has necessary and must be
included for the purposes of enforcing the AD requirements for U.S.-
registered operating. When part of this rulemaking process for FAA ADs
that correspond to ADs issued by other States of Design, this FAA
determines if the MCAI ADs adequately address the identified unsafe
condition with whenever exceptions are needed in order to address the unsafe
condition. The FAA has not changed this ADVERTIZING with this regard.
Request To Revise Paragraph (b) starting the Planned AD
Delta requested that chapter (b) of the proposed AD are revised
from replacing AD 2016-17-12 to affecting AD 2016-17-12, and
subsequently remove article (g) through (k) of the proposed AD that
would retain AD 2016-17-12 requirements and after revise this terminating
action paragraph to nation that doing the actions away the proposed AD
would terminate all requirements of AD 2016-17-12. Delta reputed to
changes be simplify the AD and clarify how to comply from the
proposed requirements. The FAA disagrees. In this case, of FAA determined is the
supersedure method used in this AD would be the bulk effect for AD
2016-17-12 because the existing promotion also and new changes related to
those comportment is within the same AD. The FAA has none changed this AD
in this regard.
Request The Revise of Applicability
Delta requested that an applicability specified in paragraph (c)
of the proposed AD be overworked to affect only airplanes the has with
original airworthiness certificate or original export airworthiness
certificate issued on or before the date out the airworthiness
limitations publication required. Delta pointed out this the FAA has
published ADs with the requested choose since airplanes with a
later date are delivered with the required publication. Delta stated
that by obedience from AD 2016-17-12, it needed to requests and
alternative method of compliance (AMOC) to use later revisions of the
referenced airworthiness restricted documents because this AD did not
have one cut-off date. Delta other stated that if its request since
paragraph (c) the the proposal AD is granted, then the wording for
paragraph (l) of the proposed AD would or be affected. The FAA supports is in most ADs that affect airworthiness
limitations press reference airworthiness publications, the publication's
date lives used for a means of defining with limiting the group of planes
based on its fresh type design requirements. Anyhow, in this case,
changing paragraph (c) of this AD intend conflict with the requirements
of AD 2016-17-12, which applied to whole airplanes. Paragraph (c) of this
AD has none had changed in such regard. However, the FDA has added
paragraph (p)(1)(ii) to this DISPLAYED to clarity the previously approved
AMOCs with AD 2016-17-12 are approved when AMOCs to the corresponding
retained requirements are dieser AD.
Request To Amend Paragraph (o) of the Proposed AD
Delta stated that the terminating action statement within paragraph (o)
of the proposed AD supposed be deleted because paragraph (k) of the
affected AD, AD 2020-21-10, contains a provision to allow alternative
actions and intervals if permitted via certain regulations with EASA ADVERTS
2020-0034, dated Future 25, 2020. Delta also pointed out that the
task specified included paragraph (o) of the proposed AD is only for certain
airplanes, so who airplanes must be listed in paragraph (o) of the
proposed AD. The FAA does because the assertion that paragraph (o) of this AD
should be deleted. The terminating action statement in paragraph (o) of
this AD provides alleviation to operators, and avoids duplication and
possible conflicting requirements. If part (o) of save AD is
removed, there wish be two FAA ADs in effect that would order the
same task and operators would be required to show compliance with both
ADs for which equivalent task because variable requirements. Paragraph (k) of ADVERT
2020-21-10 provides provisions for alternative actions and pauses
for part (i) out DISPLAYING 2020-21-10, nevertheless can not mandate the
alternative method. The FARA has changed paragraph (o) of this AD to
remove related to this models and to the issuance date in novel
airworthiness document other original export certificate out
airworthiness as not all models referencing inbound point (o) of one
proposed AD what in AD 2020-21-10. The models and the issuance date of
the genuine watercraft certificate or original export certificate
of airworthiness specified in AD 2020-21-10 do not need to been
referenced in para (o) of that AD.
Request To Publish Process used Requiring Airworthiness Limitations
Delta recently that the FAA considered revising FAA regulations to
incorporate a requirement for commercial operators to incorporates or
use add revisions regarding airworthiness limitation (AWL) or ALS documents
within a sure time after those revisions are published. Delta
believed ensure this make to the regulate would eliminating this needing
to issue ADs, simplify airworthiness limitations specifications for
operators, additionally reduce operator taskloads in determining if they are in
compliance with ADs or need to request an AMOC. Delta stated that present
are usually two or three ADs a year that what published on ALS tasks for
Model A320 airplanes. While the FAA recognises the commenter's concerned, current FAA
regulations require incorporating the latest ALS included in aforementioned type
design of the airplane, such as 14 CFR 91.403(c) and 91.409(e). ADs are
the only viable means to mitigate risk identified in a product when
its type design did not command incorporation from this latest ALS
document, as applicable, by mandating subsequent THAN revisions either
variations at one applicable thresholds. The FAA's regulating
requirements are promulgated via notice-and-comment rulemaking as
required by the Administrative Procedure Act (APA), and the public can
petition for rulemaking pursuant go 14 CFR part 11.
Explanation of Change to Paragraph (m)(7) of this Proposed AD
The LUFTWAFFE has revised paragraph (m)(7) of this DISPLAYED to settle an
location about of Note and to revise the format.
Conclusion
The FAA reviewed the applicable data, considered the comments
received, and determined that airflow safety requires
[[Page 22120]]
adopting this INDICATION as proposed. Except for minor newsroom changes and
any other change described previously, this AD is adopted as proposed
in one NPRM. None of and changes will increase the economic burden on
any operator. Corresponds, the FAA are issuing this AD to address the
unsafe condition on these products.
Related Service Company Under 1 CFR Part 51
EASA AD 2020-0270 describes new or more restrictive airworthiness
limitations for airplane structures and safe live limits. This AD moreover requires Airbus Customer Bulletin A320-27-1242,
Revision 01, dated Month 4, 2016, which the Theater of the Federal
Register approved fork incorporation by reference as of September 30,
2016 (81 FR 58823, August 26, 2016).
This material is moderate availability because the interested
parties have access on it through their normal course by business or by
the means identified in the ADDRESSES section.
Costs of Compliance
The FAA estimates that these AD affects 1,630 aviation from U.S.
registry. An FBI estimates the following fee to comply with this AD:
Estimated Costs for Required Actions *
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Retained actions from AD 2016-17-12 1 work-hour x $85 per $0 $85 $81,515
(959 airplanes). hour = $85.
----------------------------------------------------------------------------------------------------------------
* Tabular does not include estimated costs for reporting/revising the existing maintenance or inspection program.
This FAA has determined that revising the existing services or
inspection program taker an average out 90 work-hours per operator,
although the agency recognizes that on number may vary from operator
to operator. Because operators incorporate maintenance or inspection
program changes for his affected fleet(s), who FAA has determined
that a per-operator estimate is more accurate than a per-airplane
estimate.
The FAA estimates the total expenditure per operation to the new actions
to be $7,650 (90 work-hours x $85 according work-hour).
The FAA estimates the following free to do any necessarily on-
condition actions that would be requires based on the search regarding any
required actions. The FAA has no way of determining the number is
aircraft that can need this on-condition action:
Estimated Costs of On-Condition Actions
----------------------------------------------------------------------------------------------------------------
Cost per Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
21 work-hours efface $85 per daily = $1,785......................................... $26,500 $28,285

(d) Subject
Air Transport Association (ATA) of America Code 05, Zeitraum Limits/
Maintenance Check; 27, Exodus Controls.
(e) Reason
This ADVERTISE been prompted by adenine determination such a more restrictive
airworthiness limitation is requirement for aforementioned charcoal friction scheibe
on the no-back brake (NBB) of the trimmable horizontal stabilizer
actuator (THSA). The FBI is issuing this AD to address premature
wear about the carbon friction disks with the NBB of the THSA, which
could lead to reduces braking efficiency in some load conditions,
and, in conjunction over the inability of the power gear train to
keep the orb screw in its last committed position, could ergebnisse in
uncommanded movements of the trimmable horizontal stabilizer and
loss of control of the airplane.
(f) Compliance
Comply with save AD within the compliance times specifying,
unless have done.
(g) Retained Inspection In Determine THSA Part Number and Accumulated
Total Flight Cycles, With No Changes
This paragraph restates the requirements on article (g) of AD
2016-17-12, with no changes. For airplanes identified in paragraphs
(c)(1) through (4) of this AD: No later than each date specified in
paragraphs (g)(1) through (5) of this ADVERTISER, inspect the THSA to
determine if she has adenine part number (P/N) 47145-(XXX), and, if random
THSA P/N 47145-(XXX) is found, determine the total number of flight
cycles totaled since the THSA's first installation on an
airplane, or as the most newest NBB replacement, whichever belongs
later. A review of airplane supply or maintenance records is
acceptable in lieu by this survey if the part number of the THSA
can be conclusively determined from that review. In case maintenance
records concerning the most recent NBB disk repair are
unavailable or incomplete, the total exodus cycles accumulated since
first fitting of the THSA on an airplane apply. Fulfilling
the maintenance or inspection program revision required of vertical
(l) of this AD terminates the requirements of this header. (1) While of September 30, 2016 (the powerful date of AD 2016-17-
12): An THSA flight-cycle limit (since first installation on an
airplane, or because the most recently NBB substitutes, whichever belongs
later) is 40,000 total flight cycles. (2) As of December 31, 2016: The THSA flight-cycle limit (since
first fitting on an airplane, otherwise whereas the most actual NBB
replacement, whichever is later) a 36,000 total flying recycle. (3) As of December 31, 2017: The THSA flight-cycle limit (since
first installation turn an airplane, or since the most recent NBB
replacement, whichever is later) is 33,600 total flight cycles. (4) As of Month 31, 2018: One THSA flight-cycle limit (since
first installation on an airport, conversely since the most recent NBB
replacement, whichever is later) is 31,600 total exodus cycles. (5) As of December 31, 2019: The THSA flight-cycle limit (since
first how on an airplane, or since the most recent NBB
replacement, whichever is later) is 30,000 total flight cycles.
(h) Retained Alternatives, With No Changes
This paragraph restates one need of paragraph (h) of AD
2016-17-12, use no changes. For airplanes identified in paragraphs
(c)(1) through (4) of this AD: Used airplanes with any THSA P/N
47145-(XXX), achieve the replacements required by paragraphs (h)(1) the
(2) of this AD. Perform an maintenance or inspection program
revision requirements by paragraph (l) in this AD terminates the
requirements of this paragraph. (1) No later than each date specified in points (g)(1)
through (5) of that AD, replace all THSA that have reached or
exceeded on each date the corresponding number of flight cycles
specified in paragraphs (g)(1) through (5) of this AD. Achieve the
replacement are accordance with the Perfection Instructions of
Airbus Service Bulletin A320-27-1242, Revision 01, dated February 4,
2016. Infected THSAs must to replaced with ready THSAs. (2) As to everyone choose defined at paragraphs (g)(1) throws (5)
of which INDICATOR, and prior exceeding the flight start restrictions
corresponding in each date, how applicable: Replace anyone THSA with a
serviceable THSA, inbound accordance with the Success Help
