14 CFR Part 39

[Docket No. FAA-2020-0788; Product Identifier 2020-NM-091-AD; Amendment 
39-21327; AD 2020-23-11]
RIN 2120-AA64


Airworthiness Directives; Airbus SAS Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Airbus SAS Model A300 series airplanes; and Airbus SAS Model A300 B4-
600, B4-600R, and F4-600R series airplanes, and Airbus SAS Model A300 
C4-605R Variant F airplanes (collectively called Model A300-600 series 
airplanes). This AD was prompted by reports of cracking at a certain 
hole location on the left-hand (LH) side of a certain frame (FR). This 
AD requires repetitive inspections for discrepancies of certain areas 
in and around the fuselage, as specified in two European Union Aviation 
Safety Agency (EASA) ADs, which are incorporated by reference. The FAA 
is issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective January 4, 2021.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of January 4, 
2021.

SUPPLEMENTARY INFORMATION:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0110R1, dated May 27, 2020; and 
EASA AD 2020-0111R2, dated June 16, 2020 (``EASA AD 2020-0110R1'' and 
``EASA AD 2020-0111R2'') (also

[[Page 75839]]

referred to as ``the Mandatory Continuing Airworthiness Information,'' 
or ``the MCAI''); to correct an unsafe condition for all Airbus SAS 
Model A300 series airplanes and Airbus SAS Model A300-600 series 
airplanes.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to all Airbus SAS Model 
A300 series airplanes and Airbus SAS Model A300-600 series airplanes. 
The NPRM published in the Federal Register on September 1, 2020 (85 FR 
54286). The NPRM was prompted by reports of cracking at hole location 
#10 on the LH side of FR4. The NPRM proposed to require repetitive 
inspections for discrepancies of certain areas in and around the 
fuselage, as specified in two EASA ADs.
    The FAA is issuing this AD to address fatigue cracking, which could 
result in reduced structural integrity of the fuselage. See the MCAI 
for additional background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA has considered the comment 
received. FedEx indicated its support for the NPRM.

Conclusion

    The FAA reviewed the relevant data, considered the comment 
received, and determined that air safety and the public interest 
require adopting this final rule as proposed, except for minor 
editorial changes. The FAA has determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    EASA AD 2020-0110R1 describes procedures for repetitive special 
detailed inspections for discrepancies (i.e., cracking) of the fuselage 
internal structure at certain frames, windshield frame lower section 
and closing panel, fuselage skin lap joint, and center wing bottom skin 
internal angle; and applicable corrective actions (repairing 
discrepancies).
    EASA AD 2020-0111R2 describes procedures for repetitive special 
detailed inspections for discrepancies of the outer wing bottom skin 
internal joint plate, outer wing bottom skin, fuselage internal 
structure at certain frames, and windshield frame lower section and 
closing panel; and applicable corrective actions (repairing 
discrepancies).
    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 118 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.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
90 work-hours x $85 per hour = $7,650........................              $0           $7,650         $902,700
----------------------------------------------------------------------------------------------------------------

    The FAA has received no definitive data that would enable the 
agency to provide cost estimates for the on-condition actions 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.
    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.

(i) 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 
the Large Aircraft Section, International Validation Branch, send it 
to the attention of the person identified in paragraph (j) of this 
AD. Information may be emailed to: 9-AVS-AIR-730-AMOC@faa.gov. 
Before using any approved AMOC, notify your appropriate principal 
inspector, or lacking a principal inspector, the manager of the 
responsible Flight Standards Office.
    (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): Except as required by 
paragraph (i)(2) of this AD, if any service information contains 
procedures or tests that are identified as RC, those procedures and 
tests must be done to comply with this AD; any procedures or tests 
that are not identified as RC are recommended. Those procedures and 
tests that are not identified as RC may be deviated from using 
accepted methods in accordance with the operator's maintenance or 
inspection program without obtaining approval of an AMOC, provided 
the procedures and tests identified as RC can be done and the 
airplane can be put back in an airworthy condition. Any 
substitutions or changes to procedures or tests identified as RC 
require approval of an AMOC.
