Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2022-0032, dated March 3, 2022 (EASA
AD 2022-0032) (also referred to as the MCAI), to correct an unsafe
condition 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, and -273N
airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -
232, -251N, -251NX, -252N, -252NX, -253N, -253NX, -271N, -271NX, -272N,
and -272NX airplanes. Model
[[Page 22439]]
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.
This AD was prompted by the detection of several BSCU channel
failures on a newly developed BSCU, having part number (P/N) E21327307.
In the case of a loss of a single channel, the remaining channel will
control aircraft braking. However, in case of dual channel failures, a
loss of anti-skid function together with the reversion to the alternate
braking mode, and the loss of nose wheel steering on these airplanes,
could be induced. The FAA is issuing this AD to address this condition,
which, if not corrected, could lead to loss of braking performance with
significant increase in airplane stopping distance, possibly resulting
in runway excursion. See the MCAI for additional background
information.
Related Service Information Under 1 CFR Part 51
EASA AD 2022-0032 specifies procedures for replacing BSCUs with P/N
E21327307, on which a fault signature is triggered. EASA AD 2022-0032
also specifies procedures for implementing the instructions of master
minimum equipment list (MMEL) updates on the basis of which the
operator's existing MEL must be amended--that is, procedures for
revising the operator's existing FAA-approved MEL with the provisions
in the MMEL updates specified in the EASA AD. EASA AD 2022-0032 also
limits the installation of affected parts.
Airbus Alert Operators Transmission A32N025-22, Rev 00, dated
February 24, 2022, including Appendixes 1 through 4, dated February 21,
2022, defines BSCU fault signatures that may be triggered on the
airplane, and specifies procedures for replacing affected parts among
other actions.
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.
FAA's Determination
These products have been approved by the aviation authority of
another country and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with this State of Design
Authority, it has notified the FAA of the unsafe condition described in
the MCAI described above. The FAA is issuing this AD after determining
that the unsafe condition described previously is likely to exist or
develop on other products of these same type designs.
Requirements of This AD
This AD requires accomplishing the actions specified in EASA AD
2022-0032 described previously, except for any differences identified
as exceptions in the regulatory text of this AD.
EASA AD 2022-0032 requires operators to ``inform all flight crews''
of revisions to the MMEL, and thereafter to ``operate the aeroplane
accordingly.'' However, this AD does not specifically require those
actions as they are already required by FAA regulations. FAA
regulations (14 CFR 121.628(a)(2)) require operators to provide pilots
with access to all of the information contained in the operator's
existing MEL. Furthermore, 14 CFR 121.628 (a)(5) requires airplanes to
be operated under all applicable conditions and limitations contained
in the operator's existing MEL. Therefore, including a requirement in
this AD to operate the airplane according to the revised MEL would be
redundant and unnecessary. Further, compliance with such a requirement
in an AD would be impracticable to demonstrate or track on an ongoing
basis; therefore, a requirement to operate the airplane in such a
manner would be unenforceable.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation
authority (CAA) ADs as the primary source of information for compliance
with requirements for corresponding FAA ADs. The FAA has been
coordinating this process with manufacturers and CAAs. As a result,
EASA AD 2022-0032 is incorporated by reference in this AD. This AD
requires compliance with EASA AD 2022-0032 in its entirety through that
incorporation, except for any differences identified as exceptions in
the regulatory text of this AD. Using common terms that are the same as
the heading of a particular section in EASA AD 2022-0032 does not mean
that operators need comply only with that section. For example, where
the AD requirement refers to ``all required actions and compliance
times,'' compliance with this AD requirement is not limited to the
section titled ``Required Action(s) and Compliance Time(s)'' in EASA AD
2022-0032. Service information required by EASA AD 2022-0032 for
compliance will be available at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by
searching for and locating Docket No. FAA-2022-0389 after this AD is
published.
Interim Action
The FAA considers this AD interim action. If final action is later
identified, the FAA might consider further rulemaking then.
FAA's Justification and Determination of the Effective Date
Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and
comment procedures for rules when the agency, for ``good cause,'' finds
that those procedures are ``impracticable, unnecessary, or contrary to
the public interest.'' Under this section, an agency, upon finding good
cause, may issue a final rule without providing notice and seeking
comment prior to issuance. Further, section 553(d) of the APA
authorizes agencies to make rules effective in less than thirty days,
upon a finding of good cause.
An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies forgoing notice and comment prior to adoption of this rule
because dual BSCU channel failures can induce loss of anti-skid
function together with the reversion to the alternate braking mode, and
the loss of nose wheel steering, and lead to loss of braking
performance with significant increase in airplane stopping distance,
possibly resulting in runway excursion. Accordingly, notice and
opportunity for prior public comment are impracticable and contrary to
the public interest pursuant to 5 U.S.C. 553(b)(3)(B).
In addition, the FAA finds that good cause exists pursuant to 5
U.S.C. 553(d) for making this amendment effective in less than 30 days,
for the same reasons the FAA found good cause to forgo notice and
comment.
Regulatory Flexibility Act (RFA)
The requirements of the RFA do not apply when an agency finds good
cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and
comment. Because the FAA has determined that it has good cause to adopt
this rule without notice and comment, RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD affects 1,500 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
[[Page 22440]]
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 4.5 work-hours x $85 per $0 Up to $382.50................ Up to $573,750.
hour = $382.50.
----------------------------------------------------------------------------------------------------------------
The FAA has received no definitive data on which to base the cost
estimates for the replacement parts specified in this AD.
According to the manufacturer, some or all of the costs of this AD
may be covered under warranty, thereby reducing the cost impact on
affected individuals. The FAA does not control warranty coverage for
affected individuals. As a result, the FAA has included all known costs
in the cost estimate.
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, and
(2) Will not affect intrastate aviation in Alaska.

possibly resulting in runway excursion.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Requirements
Except as specified in paragraph (h) of this AD: Comply with all
required actions and compliance times specified in, and in
accordance with, European Union Aviation Safety Agency (EASA) AD
2022-0032, dated March 3, 2022 (EASA AD 2022-0032).
(h) Exceptions to EASA AD 2022-0032
(1) Where EASA AD 2022-0032 defines ``the AOT'' as ``Airbus
Alert Operators Transmission (AOT) A32N025-22 [undated],'' this AD
requires using Airbus Alert Operators Transmission A32N025-22, Rev
00, dated February 24, 2022, including Appendixes 1 through 4, dated
February 21, 2022.
(2) Where paragraph (1) of EASA AD 2022-0032 specifies
replacement of affected parts, replace the affected part in
accordance with the ``Remove and replace BSCU P/N E21327307'' step
in paragraph 5.6., ``Instructions,'' of Airbus Alert Operators
Transmission A32N025-22, Rev 00, dated February 24, 2022, including
Appendixes 1 through 4, dated February 21, 2022. No other actions in
Airbus Alert Operators Transmission A32N025-22, Rev 00, dated
February 24, 2022, including Appendixes 1 through 4, dated February
21, 2022, are required for compliance for the replacement.
(3) Where EASA AD 2022-0032 refers to its effective date, this
AD requires using the effective date of this AD.
(4) Where paragraph (2) of EASA AD 2022-0032 requires operators
to ``implement the instructions of the MMEL [master minimum
equipment list] update,'' this AD requires revising the operator's
existing FAA-approved minimum equipment list (MEL) with the
provisions specified in ``The MMEL update'' as identified in EASA AD
2022-0032.
(5) Where paragraph (2) of EASA AD 2022-0032 specifies to
``inform all flight crews, and, thereafter, operate the aeroplane
accordingly,'' this AD does not require those actions as those
actions are already required by existing FAA operating regulations.
(6) The ``Remarks'' section of EASA AD 2022-0032 does not apply
to this AD.
(i) No Reporting Requirement
Although Airbus Alert Operators Transmission A32N025-22, Rev 00,
dated February 24, 2022, including Appendixes 1 through 4, dated
February 21, 2022, specifies to report certain information and send
affected parts to the manufacturer, this AD does not include those
actions.
