Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (SNPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA is revising a notice of proposed rulemaking (NPRM) to 
supersede Airworthiness Directive (AD) 2013-25-11; this NPRM would 
apply to all Airbus SAS Model A318-111, and -112 airplanes; Model A319-
111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model 
A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Model 
A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. This 
action revises the NPRM by establishing a different compliance time for 
the initial inspection on certain airplane configurations. The FAA is 
proposing this AD to address the unsafe condition on these products. 
Since these actions would impose an additional burden over those in the 
NPRM, the FAA is reopening the comment period to allow the public the 
chance to comment on these changes.

DATES: The FAA must receive comments on this SNPRM by January 3, 2022.

rulemaking.

Background

    The FAA issued AD 2013-25-11, Amendment 39-17707 (78 FR 78705, 
December 27, 2013) (AD 2013-25-11). AD 2013-25-11 requires actions to 
address an unsafe condition on all Airbus SAS Model A318-111, -112, -
121, and -122 airplanes; Model A319-111, -112, -113, -114, -115, -131, 
-132, and -133 airplanes; Model A320-111, -211, -212, -214, -231, -232, 
and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -
231, and -232 airplanes. AD 2013-25-11 requires repetitive inspections 
of the 80VU rack lower lateral fittings, upper fittings, and shelves 
for damage, repetitive inspections of the 80VU rack lower central 
support for cracking, and corrective action if necessary. AD 2013-25-11 
also specifies optional terminating action for the repetitive 
inspections.
    The FAA issued an NPRM to amend 14 CFR part 39 by adding an AD to 
supersede AD 2013-25-11 that would apply to all Airbus SAS Model A318-
111, and -112, airplanes; Model A319-111, -112, -113, -114, -115, -131, 
-132, and -133 airplanes; Model A320-211, -212, -214, -216. -231, -232, 
and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -
231, and -232 airplanes. The NPRM published in the Federal Register on 
June 22, 2021 (86 FR 32653) (the NPRM). The NPRM was prompted by 
reports of damaged lower lateral fittings of the 80VU rack, and reports 
of new damage on airplanes on which certain optional service 
information had been accomplished. The NPRM proposed to expand the 
applicability, remove the optional terminating action, and require new 
repetitive inspections.

Actions Since the NPRM Was Issued

    Since the FAA issued the NPRM, new damage occurrences have been 
reported, and a different compliance time has been determined for 
certain affected parts, depending on airplane configuration.
    The European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Union, has issued 
EASA AD 2021-0172, dated July 20, 2021 (EASA AD 2021-0172) (also 
referred to after this as the Mandatory Continuing Airworthiness 
Information, or the MCAI), to correct an unsafe condition for all 
Airbus SAS Model A318-111, A318-112, A319-111, A319-112, A319-113, 
A319-114, A319-115, A319-131, A319-132, A319-133, A320-211, A320-212, 
A320-214, A320-215, A320-216, A320-231, A320-232, A320-233, A321-111, 
A321-112, A321-131, A321-211, A321-212, A321-213, A321-231 and A321-232 
airplanes. Model A320-215 airplanes are not certificated by the FAA and 
are not included on the U.S. type certificate data sheet; this proposed 
AD therefore does not include those airplanes in the applicability. 
EASA AD 2021-0172 supersedes EASA AD 2021-0045, dated February 16, 2021 
(EASA AD 2021-0045). The FAA NPRM corresponds to EASA AD 2021-0045. 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-
0506.
    This proposed AD was prompted by reports of damaged lower lateral 
fittings of the 80VU rack, and reports of new damage on airplanes on 
which certain optional service information had been accomplished. The 
FAA is proposing this AD to address damage or cracking of the 80VU 
fittings and supports, which could lead to possible disconnection of 
the cable harnesses to

[[Page 64094]]

one or more computers, and if occurring during a critical phase of 
flight, could result in reduced control of the airplane. See the MCAI 
for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0172 describes procedures for repetitive special 
detailed inspections of the 80VU rack lower lateral fittings, lower 
central support, upper fittings, central post, and shelves attachments 
for discrepancies (including broken fittings, missing bolts, an 
electronics rack FIN 80VU that is in contact with structure, any bush 
that has migrated, burred material, and cracks), and corrective action 
if necessary. Corrective actions include modification, repair, and 
replacement. EASA AD 2021-0172 also describes procedures for reporting 
inspection results to Airbus.
    The FAA has also reviewed Airbus Service Bulletin A320-25-1BKJ, 
Revision 02, dated April 9, 2020. Airbus Service Bulletin A320-25-1BKJ, 
Revision 02, dated April 9, 2020, describes inspections of the 80VU 
rack lower lateral fittings, lower central support, upper fittings, 
central post, and shelves attachments for discrepancies and corrective 
action.
    The FAA has also reviewed Airbus Technical Adaptation 80827186/024/
2020, Issue 1, dated September 18, 2020, which addresses discrepancies 
found in Airbus Service Bulletin A320-25-1BKJ, Revision 02, dated April 
9, 2020.
    This service information 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.

Comments

    The FAA gave the public the opportunity to participate in 
developing this rule. The following presents the comments received on 
the NPRM and the FAA's response to those comments. Air Line Pilots 
Association (ALPA), International, supported the NPRM.

Request To Incorporate New EASA AD

    American Airlines, Delta Air Lines, and United Airlines requested 
that the FAA incorporate new information into this proposed AD, because 
of the publication of EASA AD 2021-0172, which superseded EASA AD 2021-
0045.
    The FAA agrees to incorporate the new information by issuing this 
SNPRM and has revised this AD to refer to EASA AD 2021-0172 as the 
appropriate source of service information to accomplish the required 
actions.

Request To Allow Technical Adaptation (TA)

    United Airlines requested that the FAA allow the use of TA 
80827186/024/2020, Issue 1, dated September 18, 2020, to address 
inspections and corrective actions done using Airbus Service Bulletin 
A320-25-1BKJ, Revision 02, dated April 9, 2020. United Airlines stated 
that Airbus has issued TA 80827186/024/2020, Issue 1, dated September 
18, 2020, to address discrepancies in Airbus Service Bulletin A320-25-
1BKJ, Revision 02, dated April 9, 2020, which is specified in EASA AD 
2021-0045.
    The FAA agrees with the request for the reasons provided by the 
commenter. The FAA has added paragraph (i) to the proposed AD to 
specify that Airbus Service Bulletin A320-25-1BKJ, Revision 02, dated 
April 9, 2020, with corrections referenced in the Airbus Technical 
Adaptation 80827186/024/2020, Issue 1, dated September 18, 2020, is an 
acceptable method of compliance for the inspections and corrective 
actions specified in paragraphs (1), (2), and (3) of EASA AD 2021-0172.

Request To Use Drawing

    United Airlines requested that the FAA allow the use of Airbus 
Drawing (DWG) D53924082. United Airlines stated that in Airbus Service 
Bulletin A320-25-1BKJ, Revision 02, dated April 9, 2020, Config. 004, 
Figure ICN-A320-A-25XX1BKJ-A-FAPE3-00EOV-A-001-01, Sheet 2 of 2, detail 
D shows a fitting installation with a four fasteners configuration. 
United Airlines stated Airbus Drawing D53924082 indicates the fitting 
installation must have six fasteners configuration. United Airlines 
stated that Airbus confirmed it will update the service bulletin to 
show the assembly with a six fastener configuration.
    The FAA acknowledges the commenter's request and notes the 
commenter did not submit the referenced drawing. However, the FAA has 
determined the Accomplishment Instructions steps in Airbus Service 
Bulletin A320-25-1BKJ, Revision 02, dated April 9, 2020, are correct 
for most airplanes. United Airlines is one operator in Config. 004 and 
it has a unique configuration. The FAA does not consider it appropriate 
to include various provisions in an AD applicable only to an operator's 
unique configuration of affected airplanes. If an operator with an 
affected airplane cannot accomplish the required actions specified in 
the service information, or prefers to use different service 
information that is specific to their design, an alternative method of 
compliance (AMOC) can be requested in accordance with the provisions 
specified in paragraph (j)(1) of this proposed AD. The FAA has 
confirmed with EASA that the solution for United Airlines' 
configuration will be included in the next revision of the service 
information expected to be published in the fourth quarter of 2021; 
therefore, once published, based on incorporation of the Ref. 
Publications: Section of EASA AD 2021-0172 in this proposed AD, United 
Airlines may use that service information without the need for an AMOC. 
The FAA has not changed this proposed AD in this regard.

FAA's Determination

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to the FAA's bilateral agreement with the State of Design Authority, 
the FAA has been notified of the unsafe condition described in the MCAI 
and service information referenced above. The FAA is proposing this AD 
because the FAA evaluated all pertinent information and determined an 
unsafe condition exists and is likely to exist or develop on other 
products of the same type design.
    Certain changes described above expand the scope of the NPRM. As a 
result, the FAA has determined that it is necessary to reopen the 
comment period to provide additional opportunity for the public to 
comment on this SNPRM.

Proposed Requirements of This SNPRM

    This proposed AD requires accomplishing the actions specified in 
the service information described previously, except for any 
differences identified as exceptions in the regulatory text of this 
proposed AD.

Costs of Compliance

    The FAA estimates that this proposed AD affects 1,528 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

[[Page 64095]]



                                                         Estimated Costs for Required Actions *
--------------------------------------------------------------------------------------------------------------------------------------------------------
                Action                            Labor cost             Parts cost        Cost per product               Cost on U.S. operators
--------------------------------------------------------------------------------------------------------------------------------------------------------
New proposed actions..................  Up to 8 work-hours x $85 per               $0  Up to $680..............  Up to $1,039,040.
                                         hour = Up to $680.
--------------------------------------------------------------------------------------------------------------------------------------------------------
* Table does not include estimated costs for reporting.

    The FAA estimates that it would take about 1 work-hour per product 
to comply with the proposed reporting requirement in this proposed AD. 
The average labor rate is $85 per hour. Based on these figures, the FAA 
estimates the cost of reporting the inspection results on U.S. 
operators to be $129,880, or $85 per product.
    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any 
required actions. The FAA has no way of determining the number of 
aircraft that might need these on-condition actions:

                                     Estimated Costs of On-Condition Actions
----------------------------------------------------------------------------------------------------------------
              Action                       Labor cost              Parts cost             Cost per product
----------------------------------------------------------------------------------------------------------------
Repair...........................  122 work-hours x $85 per   $4,150..............  $14,520.
                                    hour = $10,370.
Replacement......................  Up to 189 work-hours x     Up to $6,928........  Up to $22,993.
                                    $85 per hour = Up to
                                    $16,065.
Modification.....................  189 work-hours x $85 per   $7,407..............  $23,472.
                                    hour = $16,065.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some or all of the costs of this 
proposed AD may be covered under warranty, thereby reducing the cost 
impact on affected operators. The FAA does not control warranty 
coverage for affected operators. As a result, the FAA has included all 
known costs in the cost estimate.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this proposed AD 
is 2120-0056. The paperwork cost associated with this proposed AD has 
been detailed in the Costs of Compliance section of this document and 
includes time for reviewing instructions, as well as completing and 
reviewing the collection of information. Therefore, all reporting 
associated with this proposed AD is mandatory. Comments concerning the 
accuracy of this burden and suggestions for reducing the burden should 
be directed to Information Collection Clearance Officer, Federal 
Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177-
1524.

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

    The FAA determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (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.

2021-0172, dated July 20, 2021 (EASA AD 2021-0172).

(h) Exceptions to EASA AD 2021-0172

    (1) Where EASA AD 2021-0172 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) The remarks section of EASA AD 2021-0172 does not apply to 
this AD.
    (3) Where paragraph (3) of EASA AD 2021-0172 specifies ``any 
discrepancy,'' for this AD ``any discrepancy'' includes broken 
fittings, missing bolts, an electronics rack FIN 80VU that is in 
contact with structure, any bush that has migrated, burred material, 
and cracks.

(i) Method of Compliance for Paragraphs (1), (2), and (3) of EASA AD 
2021-0172

    Accomplishing inspections and correctives actions in accordance 
with the Accomplishment Instruction of Airbus Service Bulletin A320-
25-1BKJ, Revision 02, dated April 9, 2020, with corrections 
referenced in the Airbus Technical Adaptation 80827186/024/2020, 
Issue 1, dated September 18, 2020, is an acceptable method of 
compliance for the inspections and corrective actions specified in 
paragraphs (1), (2), and (3) of EASA AD 2021-0172.

(j) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Large Aircraft Section, International Validation Branch, FAA, has 
the authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or responsible Flight 
Standards Office, as appropriate. If sending information directly to

    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain instructions from a manufacturer, the instructions must be 
accomplished using a method approved by the Manager, Large Aircraft 
Section, International Validation Branch, FAA; or EASA; or Airbus 
SAS's EASA Design Organization Approval (DOA). If approved by the 
DOA, the approval must include the DOA-authorized signature.
    (3) Required for Compliance (RC): For any service information
