Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2022-11-01, which applies to certain Airbus SAS Model A300 series airplanes; 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). AD 2022-11-01 requires a detailed inspection (DET) of the main landing gear (MLG) support rib 5 lower flange, a fluorescent penetrant inspection (FPI) around the spot facing of certain fastener holes if necessary, and applicable corrective actions. Since the FAA issued AD 2022-11-01, it was determined additional airplanes are affected. This proposed AD would continue to require the actions in AD 2022-11-01 and add airplanes to the applicability, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

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)
2022-11-01, which applies to certain Airbus SAS Model A300 series
airplanes; 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). AD 2022-11-01 requires a detailed
inspection (DET) of the main landing gear (MLG) support rib 5 lower
flange, a fluorescent penetrant inspection (FPI) around the spot facing
of certain fastener holes if necessary, and applicable corrective
actions. Since the FAA issued AD 2022-11-01, it was determined
additional airplanes are affected. This proposed AD would continue to
require the actions in AD 2022-11-01 and add airplanes to the
applicability, as specified in a European Union Aviation Safety Agency
(EASA) AD, which is proposed for incorporation by reference (IBR). 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 October 31,
2024.

Background
The FAA issued AD 2022-11-01, Amendment 39-22051 (87 FR 32292, May
31, 2022) (AD 2022-11-01), on certain Airbus SAS Model A300 and A300-
600 series airplanes. AD 2022-11-01 was prompted by an MCAI originated
by EASA, which is the Technical Agent for the Member States of the
European Union. EASA issued AD 2021-0190, dated August 17, 2021, to
correct an unsafe condition.
AD 2022-11-01 requires a one-time DET of the MLG support rib 5
lower flange, inboard and outboard of rib 5, on the right-hand and
left-hand sides (i.e., affected area); a one-time FPI around the spot
facing of certain fastener holes if necessary; and applicable
corrective actions. The FAA issued AD 2022-11-01 to address cracking in
the affected area. This condition, if not detected and
[[Page 75508]]
corrected, could affect the structural integrity of the airplane.
Actions Since AD 2022-11-01 Was Issued
Since the FAA issued AD 2022-11-01, EASA superseded AD 2021-0190,
dated August 17, 2021, and issued EASA AD 2024-0145, dated July 23,
2024 (EASA AD 2024-0145) (also referred to as the MCAI), to correct an
unsafe condition for certain Airbus SAS Model A300, A300-600, and A300-
600ST series airplanes. Model A300-600ST 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 MCAI states that certain airplanes were excluded
from the applicability of EASA AD 2021-0190 on the assumption they were
withdrawn from service. Since issuance of that EASA AD, it was
determined at least one of those airplanes is in service and the DET
and FPI were accomplished on that airplane. Further, there is no
evidence that the other excluded airplanes were scrapped or dismantled
so the possibility exists they could also return to service. For these
reasons, the applicability was expanded to include those airplanes.
Also, since the FAA issued AD 2022-11-01, FAA Type Certificate
A35EU was updated to remove Airbus SAS Model A300 B2-1A, B2-1C, B2K-3C,
and B2-203 airplanes. The FAA therefore is proposing to remove those
airplanes from the applicability of this proposed AD.
The FAA is proposing this AD to address the unsafe condition on
these products. You may examine the MCAI in the AD docket at
<a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2024-2141.
Material Incorporated by Reference Under 1 CFR Part 51
EASA AD 2024-0145 specifies procedures for a one-time DET of the
affected area, a one-time FPI around the spot facing of certain
fastener holes in the affected area if no crack is detected during the
DET, and obtaining and following approved repair instructions if any
crack is found during the DET or FPI. EASA AD 2024-0145 also updated
the applicability of affected airplanes.
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
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
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 accomplishing the actions specified
in EASA AD 2024-0145 described previously, except for any differences
identified as exceptions in the regulatory text of this proposed AD.
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 2024-0145 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2024-0145 in its entirety through that incorporation, except
for any differences identified as exceptions in the regulatory text of
this proposed AD. Using common terms that are the same as the heading
of a particular section in EASA AD 2024-0145 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 2024-
0145. Material required by EASA AD 2024-0145 for compliance will be
available at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2024-2141 after the
FAA final rule is published.
Costs of Compliance
The FAA estimates that this AD, adopted as proposed, would affect
124 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.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
23 work-hours x $85 per hour = $1,955........................ $0 $1,955 $242,420
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to replace any cracked rib
that would be required based on the results of any required actions and
repair status. The FAA has no way of determining the number of aircraft
that might need this on-condition action:
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Labor cost Parts cost Cost per product
------------------------------------------------------------------------
Up to 1,500 work-hours x $85 $620,000 Up to $747,500.
per hour = $127,500.
------------------------------------------------------------------------
The FAA has received no definitive data on which to base the cost
estimates for the repair specified in this AD.
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.
[[Page 75509]]
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) 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
