[Docket No. FAA-2023-1051; Project Identifier MCAI-2022-01565-T]
RIN 2120-AA64


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 A320-200 series airplanes, Model A330-200 
Freighter series airplanes, Model A330-300 series airplanes, Model 
A340-200 series airplanes, and Model A340-300 series airplanes. This 
proposed AD was prompted by a report that certain overheat detection 
system (OHDS) sensing elements, produced before January 31, 2021, may 
not properly detect thermal bleed leak events due to a quality escape 
during the manufacturing process. This proposed AD would require a one-
time special detailed inspection (SDI) for discrepancies of each 
affected part installed at an affected position, and replacement of 
discrepant parts, as specified in a European Union Aviation Safety 
Agency (EASA) AD, which is proposed for incorporation by reference 
(IBR). This proposed AD would also prohibit the installation of 
affected parts. 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 July 10, 
2023.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION: 

Comments Invited

    The FAA invites you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under ADDRESSES. Include ``Docket No. FAA-2023-1051; Project Identifier 
MCAI-2022-01565-T'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the proposal, explain the 
reason for any recommended change, and include supporting data. The FAA 
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 
Vladimir Ulyanov, Aerospace Engineer, FAA, International Validation 
Branch, 2200 South 216th St., Des Moines, WA 98198; telephone 206-231-
3229; 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 2022-0243, dated December 8, 2022 
(EASA AD 2022-0243) (also referred to as the MCAI), to correct an 
unsafe condition for all Airbus SAS Model A320-200 series airplanes, 
Model A330-200 Freighter series airplanes, Model A330-300 series 
airplanes, Model A340-200

[[Page 34098]]

series airplanes, and Model A340-300 series airplanes. The MCAI states 
that the affected part manufacturer, Kidde Aerospace & Defense, 
reported that certain OHDS sensing elements, produced before January 
31, 2021, may not properly detect thermal bleed leak events due to a 
quality escape during the manufacturing process. This condition, if not 
addressed, could lead to an air leak remaining undetected by the OHDS 
and not being isolated during flight, possibly resulting in localized 
areas of the airplane being exposed to high temperatures, with 
consequent reduced structural integrity of the airplane.
    The FAA is proposing this AD to address the unsafe condition on 
these products.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-1051.

Related Service Information Under 1 CFR Part 51

    EASA AD 2022-0243 specifies procedures for a one-time SDI for 
discrepancies of each affected part installed at an affected position, 
and replacement of discrepant parts where the displayed electronic 
centralized aircraft monitoring (ECAM) warning is not related to 
results of a heat gun test at certain locations. EASA AD 2022-0243 also 
prohibits the installation of affected parts.
    The FAA reviewed Kidde Aerospace & Defense Service Bulletin CFD-26-
3, dated January 13, 2022; and Revision 1, dated March 29, 2022, which 
identify affected OHDS sensing elements (those having certain part 
numbers and corresponding date codes). These documents are distinct 
because Revision 1 corrects typographical errors and clarifies wording.
    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 ADDRESSES.

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 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 the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in EASA 2022-0243 described previously, except for any differences 
identified as exceptions in the regulatory text of this proposed AD. 
This proposed AD would also prohibit the installation of affected 
parts.

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 2022-0243 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2022-0243 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 2022-0243 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-
0243. Service information required by EASA AD 2022-0243 for compliance 
will be available at regulations.gov under Docket No. FAA-2023-1051 
after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 119 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
----------------------------------------------------------------------------------------------------------------
Up to 64 work-hours x $85 per hour = $5,440..................              $0           $5,440         $647,360
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any 
required actions. The FAA has no way of determining the number of 
aircraft that might need these on-condition actions:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
13 work-hours x $85 per hour = $1,105.             (*)           $1,105
------------------------------------------------------------------------
* The FAA has received no definitive data on which to base the parts
  cost.

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some or all of the costs of 
this proposed AD may be covered under warranty, thereby reducing the 
cost impact on affected operators.

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 34099]]

    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.

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:

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

Airbus SAS: Docket No. FAA-2023-1051; Project Identifier MCAI-2022-
01565-T.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by July 10, 2023.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Airbus SAS airplanes specified in 
paragraphs (c)(1) through (5) of this AD, certificated in any 
category.
    (1) Model A330-201, -202, -203, -223, and -243 airplanes.

    (5) Model A340-311, -312, and -313 airplanes.

(d) Subject

    Air Transport Association (ATA) of America Code 36, Pneumatic.

(e) Unsafe Condition

    This AD was prompted by a report that certain overheat detection 
system (OHDS) sensing elements, produced before January 31, 2021, 
may not properly detect the thermal bleed leak events due to a 
quality escape during the manufacturing process. The FAA is issuing 
this AD to address an air leak remaining undetected by the OHDS 
sensing element and not being isolated during flight. The unsafe 
condition, if not addressed, could possibly result in localized 
areas of the airplane being exposed to high temperatures, with 
consequent reduced structural integrity of the airplane.

(f) Compliance

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

(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 
2022-0243, dated December 8, 2022 (EASA AD 2022-0243).

(h) Exceptions to EASA AD 2022-0243

    (1) Where EASA AD 2022-0243 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) This AD does not adopt the ``Remarks'' section of EASA AD 
2022-0243.
    (3) Where EASA AD 2022-0243 defines ``affected part'' and refers 
to ``the VSB,'' for the part numbers and date codes, for this AD, 
use Kidde Aerospace & Defense Service Bulletin CFD-26-3, dated 
January 13, 2022; or Revision 1, dated March 29, 2022, as ``the 
VSB'' for the part numbers and date codes.
    (4) Where EASA AD 2022-0243 defines Groups, replace the text 
``the SB'' with ``Airbus Service Bulletin A330-36-3052, dated June 
27, 2022; or Airbus SB A340-36-4036, dated June 27, 2022; as 
applicable.''
    (5) Where paragraph (2) of EASA AD 2022-0234 specifies action if 
``any discrepancy as defined in the SB is detected,'' for this AD a 
discrepancy is when the displayed electronic centralized aircraft 
monitoring (ECAM) warning is not related to results of a heat gun 
test at certain location.

(i) No Reporting Requirement and No Return of Parts

    (1) Although the service information referenced in EASA AD 2022-
0243 specifies to submit certain information to the manufacturer, 
this AD does not include that requirement.
    (2) Although the service information referenced in EASA AD 2022-
0243 specifies to return certain parts to the manufacturer, this AD 
does not include that requirement.

(j) Additional AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
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 International 
Validation Branch, send it to the attention of the person identified 
in paragraph (k) 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, International 
Validation Branch, FAA; or EASA; 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 (j)(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.
