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 B2K-3C, B2-203, B4-2C, and B4-203 
airplanes. This proposed AD was prompted by a determination that 
internal system pollution can occur, most likely due to corroded unions 
in the pressurization lines, with an associated risk of contamination 
of the check valves. This proposed AD would require repetitive 
inspections (functional checks) of the pressurization of the hydraulic 
system reservoirs, and corrective actions if necessary, 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.

DATES: The FAA must receive comments on this proposed AD by January 3, 
2023.

ADDRESSES: You may send comments, using the procedures found in 14 CFR

will consider all comments received by the closing date and may amend 
this proposal because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
regulations.gov, including any personal information you provide. The 
agency will also post a report summarizing each substantive verbal 
contact received about this NPRM.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by 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 Dan 
Rodina, Aerospace Engineer, Large Aircraft Section, FAA, International 
Validation Branch, 2200 South 216th St., Des Moines, WA 98198; 
telephone 206-231-3225; email [email protected]. Any commentary that 
the FAA 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 2022-0116, dated June 21, 2022 (EASA 
AD 2022-0116) (also referred to as the MCAI), to correct an unsafe 
condition for all Airbus SAS Model A300 B2-203, A300 B2K-3C, A300 B4-
203, A300 B4-2C, A300C4-203, and A300F4-203 airplanes. Model A300C4-203 
and A300F4-203 airplanes are not certificated by the FAA and are not 
included on the U.S. type certificate data sheet; this proposed AD 
therefore does not include those airplanes in the applicability.
    The MCAI states that internal system pollution can occur, most 
likely due to corroded unions at the pressurization lines, with an 
associated risk of contamination of the check valves. The three 
hydraulic system reservoirs are pressurized by air coming from the 
engine or the auxiliary power unit bleed air duct or from the ground 
connection. Air tightness of the pressurization system of the 
reservoirs is achieved by check valves that are located on the 
respective pressurization lines and on top of each hydraulic reservoir. 
The FAA is proposing this AD to address check valve contamination, 
which could lead to hydraulic reservoir pressurization issues and, if 
combined with an air pressurization line rupture, could lead to loss of 
hydraulic systems and possibly result in loss of control of the 
airplane. See the MCAI for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2022-0116 specifies procedures for repetitive detailed 
inspections by performing functional checks for air leakage of the 
hydraulic system reservoirs and corrective actions. Corrective actions 
include a fault isolation to identify the source of depressurization 
and replacement of the check valves. EASA AD 2022-0116 also specifies 
procedures for reporting the inspection findings.
    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 these same type designs.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2022-0116 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

[[Page 69224]]

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 2022-0116 by reference in the FAA final rule. 
This proposed AD would, therefore, require compliance with EASA AD 
2022-0116 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 2022-0116 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 2022-
0116. Service information required by EASA AD 2022-0116 for compliance 
will be available at regulations.gov by searching for and locating 
Docket No. FAA-2022-1412 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD would affect 2 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
----------------------------------------------------------------------------------------------------------------
4 work-hours x $85 per hour = $340..............................              $0            $340            $680
1 work-hour x $85 per hour = $85 (reporting)....................               0              85             170
----------------------------------------------------------------------------------------------------------------

    The FAA has received no definitive data on which to base the cost 
estimates for the corrective actions specified in this proposed AD.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to a penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to take 
approximately 1 hour per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Send comments regarding this burden estimate 
or any other aspect of this collection of information, including 
suggestions for reducing this burden, to: Information Collection 
Clearance Officer, Federal Aviation Administration, 10101 Hillwood 
Parkway, Fort Worth, TX 76177-1524.

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 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13   [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

Airbus SAS: Docket No. FAA-2022-1412; Project Identifier MCAI-2022-
00805-T.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by January 3, 2023.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Airbus SAS Model A300 B2K-3C, B2-203, B4-

    Comply with this AD within the compliance times specified, 
unless already done.

[[Page 69225]]

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with, European Union Aviation Safety Agency (EASA) AD 
2022-0116, dated June 21, 2022 (EASA AD 2022-0116).

(h) Exceptions to EASA AD 2022-0116

    (1) Where EASA AD 2022-0116 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) Paragraph (3) of EASA AD 2022-0116 specifies to report the 
first functional check (test) results to Airbus within a certain 
compliance time. For this AD, report the first functional check 
(test) results at the applicable time specified in paragraph 
(h)(2)(i) or (ii) of this AD.
    (i) If the inspection was done on or after the effective date of 
this AD: Submit the report within 30 days after the inspection.
    (ii) If the inspection was done before the effective date of 
this AD: Submit the report within 30 days after the effective date 
of this AD.
    (3) The ``Remarks'' section of EASA AD 2022-0116 does not apply 
to this AD.

(i) Additional 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)(2) of 
this AD. Information may be emailed to: [email protected]. 
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
