Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Airbus SAS Model A300 B4-600, B4-600R, and F4-600R series 
airplanes, and Model A300 C4-605R Variant F airplanes (collectively 
called Model A300-600 series airplanes). This proposed AD was prompted 
by a determination that new or more restrictive airworthiness 
limitations are necessary. This proposed AD would require revising the 
existing maintenance or inspection program, as applicable, to 
incorporate new or more restrictive airworthiness limitations, as 
specified in a European Union Aviation Safety Agency (EASA) AD, which 
is proposed for incorporation by reference. The FAA is proposing this 
AD to address the unsafe condition on these products.

receives which is not specifically designated as CBI will be placed in 
the public docket for this rulemaking.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0258, dated November 17, 2021 
(EASA AD 2021-0258) (also referred to as the MCAI), to correct an 
unsafe condition for all Airbus SAS Model A300-600 series airplanes.
    This proposed AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary. The FAA is 
proposing this AD to prevent reduced structural integrity of the 
airplane.
    EASA previously issued EASA AD 2019-0090, dated April 26, 2019 
(EASA AD 2019-0090), requiring the actions described in the Airbus 
A300-600 Airworthiness Limitations Section (ALS), Part 2, ``Damage 
Tolerant Airworthiness Limitation Items (DT-ALI),'' Revision 03, dated 
December 14, 2018, which also includes the limit of validity (LOV) for 
the Model A300-600 airplanes. EASA AD 2019-0090 corresponds to FAA AD 
2019-21-01, Amendment 39-19767 (84 FR 56935, October 24, 2019) (AD 
2019-21-01). Since that EASA AD was issued, Airbus published the 
Variation, as defined in EASA AD 2021-0258, which reduces the LOV for 
Model A300-600 airplanes, reflecting the engineering data that supports 
the structural maintenance program and that corresponds to the period 
of time during which it is demonstrated that Widespread Fatigue Damage 
will not occur. EASA AD 2021-0258 does not supersede EASA AD 2019-0090, 
but does specify that it invalidates the LOV as specified in the Airbus 
A300-600 ALS, Part 2. Therefore, this proposed AD would replace the 
LOVs specified in Airbus A300-600 Airworthiness Limitations Section 
(ALS), Part 2, ``Damage Tolerant Airworthiness Limitation Items (DT-
ALI),'' Revision 03, dated December 14, 2018, as required by FAA AD 
2019-21-01.
    For the reason described above, this AD requires compliance with 
the reduced LOV as specified in the variation. See the MCAI for 
additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0258 describes new or more restrictive airworthiness 
limitations for airplane LOVs. 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 the State of Design 
Authority, it has notified the FAA of the unsafe condition described in 
the MCAI referenced above. The FAA is issuing this NPRM after 
determining that the unsafe condition described previously is likely to 
exist or develop in other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations, which are specified in EASA AD 
2021-0258 described previously, as incorporated by reference. Any 
differences with EASA AD 2021-0258 are identified as exceptions in the 
regulatory text of this AD.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions. Compliance with these 
actions is required by 14 CFR 91.403(c). For airplanes that have been 
previously modified, altered, or repaired in the areas addressed by 
this proposed AD, the operator may not be able to accomplish the 
actions described in the revisions. In this situation, to comply with 
14 CFR 91.403(c), the operator must request approval for an alternative 
method of compliance according to paragraph (j)(1) of this proposed AD.
    As described in FAA Advisory Circular 120-104 (https://www.faa.gov/documentLibrary/media/Advisory_Circular/120-104.pdf), several programs 
have been developed to support initiatives that will ensure the 
continued airworthiness of aging airplane structure. The last element 
of those initiatives is the requirement to establish a LOV of the 
engineering data that support the structural maintenance program under 
14 CFR 26.21. This proposed AD is the result of an assessment of the 
previously established programs by the design approval holder (DAH) 
during the process of establishing the LOV for the affected airplanes. 
The actions specified in this proposed AD are necessary to complete 
certain programs to ensure the continued airworthiness of aging 
airplane structure and to support an airplane reaching its LOV.

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, the 
FAA proposes to incorporate EASA AD 2021-0258 by reference in the FAA 
final rule. Service information required by EASA AD 2021-0258 for 
compliance will be available at https://www.regulations.gov by 
searching for and locating Docket No. FAA-2022-0505 after the FAA final 
rule is published.

Airworthiness Limitation ADs Using the New Process

    The FAA's process of incorporating by reference MCAI ADs as the 
primary source of information for compliance with corresponding FAA ADs 
has been limited to certain MCAI ADs (primarily those with service 
bulletins as the primary source of information for accomplishing the 
actions required by the FAA AD). However, the FAA is now expanding the 
process to include MCAI ADs that require a change to airworthiness 
limitation documents, such as airworthiness limitation sections.
    For these ADs that incorporate by reference an MCAI AD that changes

[[Page 27031]]

airworthiness limitations, the FAA requirements are unchanged. 
Operators must revise the existing maintenance or inspection program, 
as applicable, to incorporate the information specified in the new 
airworthiness limitation document. The airworthiness limitations must 
be followed according to 14 CFR 91.403(c) and 91.409(e).
    The previous format of the airworthiness limitation ADs included a 
paragraph that specified that no alternative actions (e.g., 
inspections) or intervals may be used unless the actions and intervals 
are approved as an alternative method of compliance (AMOC) in 
accordance with the procedures specified in the AMOCs paragraph under 
``Additional FAA Provisions.'' This new format includes a ``New 
Provisions for Alternative Actions and Intervals'' paragraph that does 
not specifically refer to AMOCs, but operators may still request an 
AMOC to use an alternative action or interval.

Costs of Compliance

    The FAA estimates that this proposed AD would affect 110 airplanes 
of U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:
    The FAA has determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although the agency recognizes that this number may vary from operator 
to operator. Since operators incorporate maintenance or inspection 
program changes for their affected fleet(s), the FAA has determined 
that a per-operator estimate is more accurate than a per-airplane 
estimate. Therefore, the agency estimates the average total cost per 
operator to be $7,650 (90 work-hours x $85 per work-hour).

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) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
