14 CFR Part 39

[Docket No. FAA-2021-1075; Project Identifier MCAI-2021-00856-T; 
Amendment 39-22077; AD 2022-12-05]
RIN 2120-AA64


Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2020-26-
01, which applied to all Airbus SAS Model A318-111, -112, -121, and -
122 airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and 
-133 airplanes; and Model A320-211, -212, -214, -216, -231, -232, and -
233 airplanes. AD 2020-26-01 required repetitive general visual 
inspections of the affected main landing gear (MLG) sliding tubes for 
cracks, and replacement if necessary. This AD was prompted by reports 
of cracks found on MLG sliding tubes that may have been subject to 
improperly performed magnetic particle inspection. This AD requires 
repetitive general visual inspections of the affected MLG sliding tubes 
(both retained affected parts and additional affected parts) for 
cracks, and replacement if necessary, as specified in a European Union 
Aviation Safety Agency (EASA) AD, which is incorporated by reference. 
This AD also adds airplanes to the applicability. The FAA is issuing 
this AD to address the unsafe condition on these products.

DATES: This AD is effective September 2, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of September 2, 
2022.

SUPPLEMENTARY INFORMATION: 

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0175, dated July 22, 2021; 
corrected July 23, 2021 (EASA AD 2021-0175) (also referred to as the 
MCAI), to correct an unsafe condition for all Airbus SAS Model A318-
111, A318-112, A318-121, A318-122, 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 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 to supersede AD 2020-26-01, Amendment 39-21356 (85 FR 
82299, December 18, 2020) (AD 2020-26-01). AD 2020-26-01 applied to all 
Airbus SAS Model A318-111, -112, -121, and -122 airplanes; Model A319-
111, -112, -113, -114, -115, -131, -132, and -133 airplanes; and Model 
A320-211, -212, -214, -216, -231, -232, and -233 airplanes. The NPRM 
published in the Federal Register on December 27, 2021 (86 FR 73197). 
The NPRM was prompted by reports of cracks found on MLG sliding tubes 
that may have been subject to improperly performed magnetic particle 
inspection. The NPRM proposed to require repetitive general visual 
inspections of the affected MLG sliding tubes (both retained affected 
parts and additional affected parts) for cracks, and replacement if 
necessary, as specified in EASA AD 2021-0175. The NPRM also proposed to 
add airplanes to the applicability.
    The FAA is issuing this AD to address cracks on the MLG sliding 
tubes, which could cause MLG sliding tube fracture, and could result in 
the MLG collapsing, damage to the airplane, and injury to occupants. 
See the MCAI for additional background information.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from the Air Line Pilots Association, 
International (ALPA), who supported the NPRM without change.
    The FAA also received a comment from Delta Air Lines (DAL). The 
following presents the comment received on the NPRM and the FAA's 
response.

Request for Clarification of Inspection Requirements

    DAL requested clarification of the language specified in paragraph 
(6) of EASA AD 2021-0175 that ``following installation, the part is 
inspected as required by this [EASA] AD.'' DAL stated that more than 
one interpretation is possible, but it presumed the intent to be that 
an affected part can only be

[[Page 45628]]

installed if it is inspected within the compliance time specified in 
paragraph (1) of EASA AD 2021-0175 (rather than requiring an inspection 
immediately after installing an affected part on-wing).
    The FAA agrees to clarify the referenced quote. The statement 
``following installation, the part is inspected as required by this 
[EASA] AD'' does not mean an inspection is required before further 
flight after installing an affected part. Instead, it means that the 
part must meet the inspection requirements of paragraph (1) of EASA AD 
2021-0175 at the applicable compliance times specified in paragraph (1) 
of EASA AD 2021-0175.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
received, and determined that air safety requires adopting this AD as 
proposed. Except for minor editorial changes, this AD is adopted as 
proposed in the NPRM. None of the changes will increase the economic 
burden on any operator. Accordingly, the FAA is issuing this AD to 
address the unsafe condition on these products.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0175 describes procedures for repetitive general 
visual inspections of the MLG sliding tubes for cracks, and replacement 
if necessary. EASA AD 2021-0175 also describes terminating actions for 
the repetitive inspections of affected MLG sliding tubes by either 
overhauling an affected MLG sliding tube or replacing an affected MLG 
sliding tube with an MLG sliding tube that is not affected.
    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 affects 1,524 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.

                                         hour = $170.
----------------------------------------------------------------------------------------------------------------

    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:

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,
    (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.
