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 series airplanes, and 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 reports of cracking at a 
certain hole location on the left-hand (LH) side of a certain frame 
(FR). This proposed AD would require repetitive inspections for 
discrepancies of certain areas in and around the fuselage, as specified 
in two European Union Aviation Safety Agency (EASA) ADs, which will be 
incorporated by reference. The FAA is proposing this AD to address the 
unsafe condition on these products.

its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), 
CBI is exempt from public disclosure. If your comments responsive to 
this NPRM contain commercial or financial information that is 
customarily treated as private, that you actually treat as private, and 
that is relevant or responsive to this NPRM, it is important that you 
clearly designate the submitted comments as CBI. Please mark each page 
of your submission containing CBI as ``PROPIN.'' The FAA will treat 
such marked submissions as confidential under the FOIA, and they will 
not be placed in the public docket of this NPRM. Submissions containing 
CBI should be sent to the person identified in the FOR FURTHER 
INFORMATION CONTACT section. Any commentary that the FAA receives which 
is not specifically designated as CBI will be placed in the public 
docket for this rulemaking.

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 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.

[[Page 54287]]

    This proposed AD was prompted by reports of cracking at hole 
location #10 on the LH side of FR4. The FAA is proposing this AD to 
address fatigue cracking, which could result in reduced structural 
integrity of the fuselage. See the MCAI for additional background 
information.

Related IBR Material 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 inspection 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.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, the FAA 
has been notified of the unsafe condition described in the MCAI 
referenced above. The FAA is proposing this AD because the FAA has 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Proposed AD Requirements

    This proposed AD would require, accomplishing the actions specified 
in EASA AD 2020-0110R1 and EASA AD 2020-0111R2 described previously, as 
incorporated by reference. Any differences with EASA AD 2020-0110R1 and 
EASA AD 2020-0111R2 are identified as exceptions in the regulatory text 
of this AD.
    For the action specified in paragraph (4) of EASA AD 2020-0110R1, 
the compliance times vary depending on airplane configuration, 
inspection type, and inspection results. The initial compliance times 
for the inspections vary between before the accumulation of 18,500 
flight cycles and 24,500 flight cycles since the first flight of the 
airplane. The repetitive intervals for the inspections vary between 
1,500 flight cycles and 12,600 flight cycles, depending on inspection 
results. See Airbus Service Bulletin A300-53-0265, Revision 6, dated 
July 2, 2012, for more information.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA initially worked with Airbus and EASA to develop a 
process to use certain EASA ADs as the primary source of information 
for compliance with requirements for corresponding FAA ADs. The FAA has 
since coordinated with other manufacturers and civil aviation 
authorities (CAAs) to use this process. As a result, EASA AD 2020-
0110R1 and EASA AD 2020-0111R2 will be incorporated by reference in the 
FAA final rule. This proposed AD would, therefore, require compliance 
with EASA AD 2020-0110R1 and EASA AD 2020-0111R2 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 the 
EASA AD 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 the EASA AD.
    Service information specified in EASA AD 2020-0110R1 and EASA AD 
2020-0111R2 that is required for compliance with EASA AD 2020-0110R1 
and EASA AD 2020-0111R2 will be available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-
0788 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 118 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
----------------------------------------------------------------------------------------------------------------
90 work-hours x $85 per hour = $7,650........................              $0           $7,650         $902,700
----------------------------------------------------------------------------------------------------------------

    The FAA has received no definitive data that would enable us to 
provide cost estimates for the on-condition actions specified in this 
proposed 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

    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,

[[Page 54288]]

    (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.
