RIN 2120-AA64


Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2019-07-05, which applies to all Airbus SAS Model A318 series 
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. AD 2019-07-05 requires repetitive inspections for 
cracking of the 10VU rack fitting lugs and repair of any cracking. 
Since the FAA issued AD 2019-07-05, it was determined that certain 
repetitive inspection intervals need to be revised. This proposed AD 
would retain the requirements of AD 2019-07-05, with reduced compliance 
times and would remove airplanes having a certain modification from the 
applicability. The FAA is proposing this AD to address the unsafe 
condition on these products.

DATES: The FAA must receive comments on this proposed AD by August 28, 
2023.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Background

    The FAA issued AD 2019-07-05, Amendment 39-19616 (84 FR 16386, 
April 19, 2019; corrected May 10, 2019 (84 FR 20542)) (AD 2019-07-05), 
for all Airbus SAS Model A318 series 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. AD 2019-07-05 was 
prompted by an MCAI originated by the European Union Aviation Safety 
Agency (EASA), which is the Technical Agent for the Member States of 
the European Union. EASA issued AD 2018-0131, dated June 19, 2018 (EASA 
AD 2018-0131), to correct an unsafe condition.
    AD 2019-07-05 requires repetitive inspections for cracking of the 
10VU rack fitting lugs, and repair of any cracking. The FAA issued AD 
2019-07-

[[Page 44741]]

05 to address reading difficulties of flight-critical information 
displayed to the flightcrew during a critical phase of flight, such as 
an approach or takeoff, which could result in loss of airplane control 
at an altitude insufficient for recovery.

Actions Since AD 2019-07-05 Was Issued

    Since the FAA issued AD 2019-07-05, EASA superseded EASA AD 2018-
0131 and issued EASA AD 2022-0266, dated December 22, 2022 (EASA AD 
2022-0266) (referred to after this as the MCAI) to correct an unsafe 
condition on certain Airbus SAS Model A318 series airplanes; Model 
A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model 
A320-211, -212, -214, -215, -216, -231, -232, and -233 airplanes; and 
Model A321-111, -112, -131, -211, -212, -213, -231 and -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. 
Airplanes on which Airbus modification 157335 has been embodied in 
production are not included in the applicability because modification 
157335 addresses the unsafe condition. The MCAI states that during an 
unscheduled maintenance operation on an A330 airplane, the 10VU rack 
was removed for access and cracks were discovered on 10VU rack side 
fittings on lugs 1, 3 and 4. As a similar design is installed on A320 
family airplanes, a sampling review was done to determine the possible 
fleet impact. The result showed that several airplanes had cracked or 
broken 10VU rack side fittings. This condition, if not detected and 
corrected, could lead to a high vibration level on the primary flight 
and navigation displays during critical flight phases (take-off and 
landing), possibly creating reading difficulties for the crew.
    Since EASA AD 2018-0131 was issued, it was determined that certain 
repetitive inspection intervals need to be revised, based on in-service 
reports and completed analysis. This proposed AD would retain the 
requirements of AD 2019-07-05, with reduced compliance times and 
airplanes on which Airbus modification 157335 has been embodied in 
production removed from the applicability. The FAA is proposing this AD 
to address reading difficulties of flight-critical information 
displayed to the flightcrew during a critical phase of flight, such as 
an approach or takeoff, which could result in loss of airplane control 
at an altitude insufficient for recovery.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-1409.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Airbus Service Bulletins A320-92-1087, Revision 
04, dated May 16, 2022; and A320-92-1119, Revision 02, dated May 16, 
2022. This service information specifies procedures for repetitive 
inspections for cracking of the 10VU rack fitting lugs, and repair of 
any cracking. These documents are distinct since they apply to 
different airplane configurations. 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.

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 this State of Design Authority, it 
has notified the FAA of the unsafe condition described in the MCAI and 
service information described above. The FAA is issuing this NPRM after 
determining that unsafe condition described previously is likely to 
exist or develop on other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would retain certain requirements of AD 2019-07-
05. This proposed AD would require accomplishing the actions specified 
in the service information described previously. This proposed AD would 
also require sending the inspection results to Airbus SAS.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 461 airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
               Action                        Labor cost           Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
Inspections (retained actions from    2 work-hours x $85 per               $0             $170          $78,370
 AD 2019-07-05).                       hour = $170.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates that it would take about 1 work-hour per product 
to comply with the reporting requirement in this 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 $85 
per product.
    The FAA estimates the following costs to do any necessary repairs 
that would be required based on the results of the inspection. The FAA 
has no way of determining the number of aircraft that might need these 
repairs:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
83 work-hours x $85 per hour = $7,055.          $9,140          $16,195

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 a 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 OMB 
Control Number for this information collection is 2120-0056. Public

[[Page 44742]]

reporting for this collection of information is estimated to take 
approximately 1 hour per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Send comments regarding this burden estimate 
or any other aspect of this collection of information, including 
suggestions for reducing this burden, 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 has 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.
