SUPPLEMENTARY INFORMATION:
Background
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
A318 series airplanes; Model A319 series airplanes; Model A320-211, -
212, -214, -216, -231, -232, -233, -251N, -252N, -253N, -271N, -272N,
and -273N airplanes; and Model A321 series airplanes. The NPRM
published in the Federal Register on December 6, 2022 (87 FR 74519).
The NPRM was prompted by AD 2022-0147, dated July 14, 2022; corrected
August 17, 2022, issued by EASA, which is the Technical Agent for the
Member States of the European Union (EASA AD 2022-0147) (also referred
to as the MCAI). 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.
In the NPRM, the FAA proposed to require a one-time detailed
inspection of each affected part installed at an affected position
(i.e., a position identified as functional item number (FIN) 34HF, FIN
35HF, FIN 61HF or FIN 62HF) and replacement as applicable, and would
prohibit the installation of affected parts at affected positions, as
specified in EASA AD 2022-0147. The FAA is issuing this AD to address
OHDS sensing elements that do not properly detect thermal bleed leak
events, which could result in an air leak remaining undetected by the
OHDS at an affected position and not being isolated during flight,
possibly resulting in localized areas of the main landing gear bay and
keel beam being exposed to high temperatures, and consequent reduced
structural integrity of the airplane.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2022-1491.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from Air Line Pilots Association,
International (ALPA), who supported the NPRM without change.
The FAA received additional comments from United Airlines. The
following presents the comments received on the NPRM and the FAA's
response to each comment.
Request To Revise Exception Language
United Airlines requested that the FAA clarify the exception to
EASA AD 2022-0147 specified in paragraph (h)(1) of the proposed AD.
Section 1.A. of Kidde Aerospace & Defense Service Bulletin CFD-26-3,
dated January 13, 2022; or Revision 1, dated March 29, 2022; states
that the date code is A2105, or January 31, 2021. Section 1.C under
Reason of the Kidde Aerospace & Defense Service Bulletin CFD-26-3
states, ``CFD sensing elements produced between November 24, 2004, and
January 31, 2021, may not properly detect thermal bleed leak events.''
Kidde Aerospace & Defense Service Bulletin CFD-26-3 states two
different time constraints. The commenter asked the FAA to identify the
correct time constraint including the serial number equivalent of the
date code restriction ``A2105.''
The FAA agrees that parts produced prior to November 24, 2004, and
after January 31, 2021, do not have the problem identified in this AD.
In order to provide additional clarity, paragraph (h)(1) of this AD has
been updated accordingly.
Request To Provide Serial Number to Date Code A2105
United Airlines requested that the FAA provide the corresponding
serial numbers to Date Code A2105.
The FAA disagrees. Kidde Aerospace & Defense Service Bulletin CFD-
26-3, dated January 13, 2022; and Revision 1, dated March 29, 2022;
specify the affected part numbers and date code, which is sufficient to
identify parts subject to the requirements of this AD. Any listed part
number that was manufactured between November 24, 2004, and the 5th
week of January 2021, regardless of serial number, is an affected part,
as defined by the MCAI and this AD.
Request for Method To Mark Passing Units
United Airlines requested that the FAA specify what is being used
to mark units that pass test requirements.
Part of the required actions of the Kidde Aerospace & Defense
Service Bulletin CFD-26-3 is to mark one of the connector hex nuts. The
marking method has been intentionally left at a high level to allow for
local and regional customers to utilize their best marking practice.
This can be achieved with a permanent marker and clear coat, paint, or
a ceramic dye. Typically, a continuous fire detection (CFD) sensor may
be removed 2-3 times in a 20- to 25-year life span of an airplane life
to gain access to adjacent equipment that requires maintenance. Based
on some open-end wrench trials at a Kidde lab, the marking was legible
after many additional attempts at installing and removing the CFD
sensors. It is standard practice to call out a part marking
specification for that part of the process. For example MIL-STD 130 is
one such common industry specification that is often used. The FAA
considers this marking method as reasonable to achieve the necessary
level of robustness over the service life of the aircraft, but
operators may use other methods that result in legible and permanent
markings.
Conclusion
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 this State of
[[Page 32630]]
Design Authority, it has notified the FAA of the unsafe condition
described in the MCAI referenced above. The FAA reviewed the relevant
data, considered the comments received, and determined that air safety
requires adopting this AD as proposed. Accordingly, the FAA is issuing
this AD to address the unsafe condition on this product. Except for
minor editorial changes, and any other changes described previously,
this AD is adopted as proposed in the NPRM. None of the changes will
increase the economic burden on any operator.
Related Service Information Under 1 CFR Part 51
EASA AD 2022-0147 specifies procedures for a one-time special
detailed inspection (SDI) of each OHDS sensing element installed at an
affected position to detect discrepancies (an incorrect electronic
centralized aircraft monitor (ECAM) alert (one not related to AIR L
WING LEAK) being displayed following the inspection of any OHDS sensing
element) and, depending on findings, replacement of any affected part
with a serviceable part. EASA AD 2022-0147 also prohibits the
installation of affected parts at affected positions.
Kidde Aerospace & Defense Service Bulletin CFD-26-3, dated January
13, 2022; and Revision 1, dated March 29, 2022; specify the part
numbers and corresponding date codes of the affected OHDS sensing
elements.
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 1,836 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
----------------------------------------------------------------------------------------------------------------
6 work-hours x $85 per hour = $510........................... $0 $510 $936,360
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition action 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 this on-condition action:
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Labor cost Parts cost Cost per product
------------------------------------------------------------------------
1 work-hour x $85 per hour = $85 $1,645............ $1,730 (per OHDS
sensing element).
------------------------------------------------------------------------
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some or all of the costs of
this 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.
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.

system (OHDS) sensing elements installed at certain positions might
not properly detect thermal bleed leak events due to a quality
escape during the manufacturing process. The FAA is issuing this AD
to address OHDS sensing elements that do not properly detect thermal
bleed leak events. The unsafe condition, if not addressed, could
result in an air leak remaining undetected by the OHDS at an
affected position and not being isolated during flight, possibly
resulting in localized areas of the main landing gear bay and keel
beam being exposed to high temperatures, and 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
2022-0147, dated July 14, 2022; corrected August 17, 2022 (EASA AD
2022-0147).
(h) Exceptions to EASA AD 2022-0147
(1) Where EASA AD 2022-0147 defines ``Affected part'' and
identifies part numbers and corresponding date codes as those
``listed in Section 1.A of the VSB,'' for this AD, those part
numbers and corresponding date codes are listed in Section 1.A. of
Kidde Aerospace & Defense Service Bulletin CFD-26-3, dated January
13, 2022; or Revision 1, dated March 29, 2022. The date codes listed
in Section 1.A. of Kidde Aerospace & Defense Service Bulletin CFD-
26-3, dated January 13, 2022; and Revision 1, dated March 29, 2022;
do not apply to parts produced prior to November 24, 2004, or after
January 31, 2021.
(2) Where EASA AD 2022-0147 refers to its effective date, this
AD requires using the effective date of this AD.
(3) Where paragraph (2) of EASA AD 2022-0147 refers to ``any
discrepancy as defined in the SB,'' for this AD, a discrepancy is an
incorrect electronic centralized aircraft monitor (ECAM) alert (one
not related to AIR L WING LEAK) being displayed following the
inspection of any OHDS sensing element.
(4) Where the service information referenced in EASA AD 2022-
0147 specifies to send an affected part to the manufacturer, this AD
does not include that requirement.
(5) This AD does not adopt the ``Remarks'' section of EASA AD
2022-0147.
(i) No Reporting Requirement
Although the service information referenced in EASA AD 2022-0147
specifies to submit certain information 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: <a href="/cdn-cgi/l/email-protection#e4ddc9a5b2b7c9a5adb6c9d3d7d4c9a5a9aba7a4828585ca838b92"><span class="__cf_email__" data-cfemail="31081c7067621c7078631c0602011c707c7e72715750501f565e47">[email protected]</span></a>.
