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) 2017-18-
17, which applied to all Airbus SAS Model A300 B4-603, A300 B4-620, 
A300 B4-622, A300 B4-605R, A300 B4-622R, A300 F4-605R, A300 F4-622R, 
and A300 C4-605R Variant F airplanes. AD 2017-18-17 required modifying 
certain fuselage frames and a repair on certain modified airplanes. 
This AD continues to require the actions in AD 2017-18-17, and also 
requires, for certain airplanes, an inspection to determine if rotating 
probe inspections were performed prior to oversizing of the open-holes, 
and repair if necessary; as specified in a European Union Aviation 
Safety Agency (EASA) AD, which is incorporated by reference. This AD 
was prompted by a report indicating that the material used to 
manufacture the upper frame feet was changed and negatively affected 
the fatigue life of the frame feet, and a determination that more work 
is required for certain airplanes that were previously modified. The 
FAA is issuing this AD to address the unsafe condition on these 
products.

DATES: This AD is effective December 14, 2020.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 14, 
2020.

SUPPLEMENTARY INFORMATION:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0051, dated March 11, 2020 
(``EASA AD 2020-0051'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for all Airbus SAS Model A300 B4-603, A300 B4-620, A300 B4-
622, A300 B4-605R, A300 B4-622R, A300 F4-605R, A300 F4-622R, A300 C4-
620, and A300 C4-605R Variant F airplanes. Model A300 C4-620 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 2017-18-17, Amendment 39-19026 (82 FR 
43160, September 14, 2017) (``AD 2017-18-17''). AD 2017-18-17 applied 
to all Airbus SAS Model A300 B4-603, A300 B4-620, A300 B4-622, A300 B4-
605R, A300 B4-622R, A300 F4-605R, A300 F4-622R, and A300 C4-605R 
Variant F airplanes. The NPRM published in the Federal Register on June 
8, 2020 (85 FR 35016). The NPRM was prompted by a report indicating 
that the material used to manufacture the upper frame feet was changed 
and negatively affected the fatigue life of the frame feet, and a 
determination that more work is

[[Page 71239]]

required for certain airplanes that were previously modified. The NPRM 
proposed to continue to require the actions in AD 2017-18-17, as 
specified in an EASA AD. The NPRM also proposed to require, for certain 
airplanes, an inspection to determine if rotating probe inspections 
were performed prior to oversizing of the open-holes, and repair if 
necessary, as specified in an EASA AD.
    The FAA is issuing this AD to address cracking of the center 
section of the fuselage, which could result in a ruptured frame foot 
and reduced structural integrity of the airplane. See the MCAI for 
additional background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The following presents the comment received 
on the NPRM and the FAA's response to each comment.

Request for Credit for Using Previous Service Information

    FedEx requested that the FAA provide credit for accomplishing the 
required actions using Airbus SAS Service Bulletin A300-53-6178, dated 
March 17, 2015, provided the appropriate rotating probe inspection is 
performed before oversizing the open holes. FedEx stated that its fleet 
is already in compliance with the required actions but used Airbus 
Service Bulletin A300-53-6178, dated March 17, 2015, not the current 
revision Airbus Service Bulletin A300-53-6178, Revision 01, dated 
September 20, 2019.
    The FAA disagrees with the request. This AD incorporated by 
reference EASA AD 2020-0051 as the appropriate material to use to 
comply with this AD. Paragraph (3) of EASA AD 2020-0051 specifies that, 
for airplanes on which the modification specified in Airbus Service 
Bulletin A300-53-6178, dated March 17, 2015, was accomplished, 
additional work must be done. That additional work consists of 
determining whether or not a rotating probe inspection was performed 
before oversizing of the open-holes and, depending on findings, 
additional corrective actions. Therefore, the credit the commenter 
requested is already included in the requirements of this AD. The FAA 
has not revised this AD in this regard.

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 IBR Material Under 1 CFR Part 51

    EASA AD 2020-0051 describes procedures for modifying certain 
fuselage frames; a repair on certain modified airplanes; and, for 
certain airplanes, an inspection to determine if a rotating probe 
inspection was performed prior to oversizing of the open-holes, 
contacting the manufacturer for post-modification work instructions, 
and repair. 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 65 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions

                                hour = $85.
----------------------------------------------------------------------------------------------------------------

    The FAA has received no definitive data that would enable providing 
cost estimates for the on-condition repairs 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.
