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 
A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, C4-620, C4-605R 
Variant F, F4-605R and F4-622R airplanes, Model 300 F4-608ST airplanes, 
Model A310-203, -203C, -204, -221, -222, -304, -308, -322, -324, and -
325 airplanes, Model A318-111, -112, -121, and -122 airplanes, Model 
A319-111, -112, -113, -114, -115, -131, -132, -133, -151N, -153N, and -
171N airplanes, Model A320-211, -212, -214, -215, -216, -231, -232, -
233, -251N, -252N, -253N, -271N, -272N, and -273N airplanes, Model 
A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -252N, -
253N, -271N, -272N, -251NX, -252NX, -253NX, -271NX, and -272NX 
airplanes, Model A330-201, -202, -203, -223, -243, -223F, -243F, -301, 
-302, -303, -321, -322, -323, -341, -342, -343, -743L, -841, and -941 
airplanes, and Model A340-211, -212, -213, -311, -312, -313, -541, -
542, -642, and -643 airplanes. Model A300 F4-608ST, A300 C4-620, A310-
203C, A310-308, A320-215, A330-743L, A340-542, and A340-643 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 NPRM published in the Federal 
Register on March 22, 2024 (89 FR 20360). The NPRM was prompted by AD 
2023-0209, dated November 22, 2023, issued by EASA, which is the 
Technical Agent for the Member States of the European Union (EASA AD 
2023-0209). EASA AD 2023-0209 states occurrences were reported of 
chemical oxygen generators failing to activate in service and during 
maintenance activities. Subsequent investigations identified poor 
reactivity of the start powder used inside the oxygen generator. This 
condition, if not corrected, could lead to a reduction of the available 
oxygen capacity of the airplane, possibly resulting in injury to the 
airplane occupants.
    In the NPRM, the FAA proposed to require replacing affected oxygen 
generators, as specified in EASA AD 2023-0209. The NPRM also proposed 
to prohibit the installation of affected parts. The FAA is issuing this 
AD to address the unsafe condition on these products.

Actions Since the NPRM Was Issued

    Since the FAA issued the NPRM, EASA superseded EASA AD 2023-0209

[[Page 8886]]

and issued EASA AD 2024-0198, dated October 18, 2024 (EASA AD 2024-
0198) (also referred to as the MCAI), to correct an unsafe condition 
for the airplanes identified in EASA AD 2023-0209, as well as Model 
A321-253NY airplanes. The MCAI states that a new airplane model (A321-
253NY) has been certified, and although affected parts could be 
installed on Model A321-253NY airplanes in service, no Model A321-253NY 
airplane has yet been delivered to operators. The MCAI also states that 
for airplanes previously affected by EASA AD 2023-0209, this EASA AD 
retains the requirements of that AD, with no additional actions.
    The FAA has confirmed that there are no Model A321-253NY airplanes 
on the U.S. Register, and no new actions are required by EASA AD 2024-
0198. Therefore, the FAA has revised paragraphs (g) and (h)(1) of this 
AD to refer to EASA AD 2024-0198.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-0471.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from Delta Air Lines (Delta) and United 
Airlines (United). The following presents the comments received on the 
NPRM and the FAA's response to each comment.

Requests To Remove Requirement To Return Parts

    Delta and United requested removal of the requirement to return 
affected oxygen generators to Collins Aerospace, as specified in 
paragraph (h)(3) of the proposed AD. Delta stated that oxygen 
generators removed before the effective date of the AD will have 
already been shipped for offsite disposal in accordance with Delta's 
procedures,\1\ which specify that an oxygen generator removed as 
unserviceable and not intended to be reinstalled on an airplane is 
manually activated to allow the release of oxygen prior to shipment for 
offsite disposal.
---------------------------------------------------------------------------

    \1\ Delta follows Federal Aviation Regulations (Reference DOT 
HM-224B (49 CFR parts 173, 175 and 178)) and federal and local 
hazardous waste disposal for handling and shipping requirements.
---------------------------------------------------------------------------

    Delta added that the service information referenced in EASA AD 
2023-0209 specifies to return affected oxygen generators to Collins 
Aerospace with the instruction ``DO NOT activate the generator (it must 
be shipped not activated, but secured with safety pin, for the purpose 
of the investigation).'' Delta stated that this instruction will result 
in significant changes to current procedures that comply with DOT 
HM224B and hazardous waste disposal requirements, and may also infringe 
on some state-specific hazardous waste requirements.
    United concurred with the requirements of the proposed AD, except 
for the requirement to ship affected oxygen generators to the original 
equipment manufacturer (OEM). United stated that transporting 
discrepant oxygen generators increases the risk to an operator of being 
noncompliant with HAZMAT/DG regulations.\2\ United asserted that 
returning suspect oxygen generators would not enhance the level of 
safety for airline operators, but would do the opposite. According to 
United, Collins Aerospace confirmed that their testing showed that the 
suspect failure condition has been contained to a few lots, and that 
the return of suspect units from participating operators will further 
validate the containment of the total population of affected units. 
United therefore concluded that the return of affected oxygen 
generators should be voluntary.
---------------------------------------------------------------------------

    \2\ 49 CFR 173.168.
---------------------------------------------------------------------------

    The FAA agrees to remove the requirement to return affected oxygen 
generators to Collins Aerospace due to the risk of noncompliance with 
HAZMAT/DG regulations. Although EASA has indicated that returning 
affected parts will help determine the cause of the unsafe condition, 
the FAA has determined that the data obtained from the returned parts 
does not outweigh the risk of noncompliance with HAZMAT/DG regulations. 
Therefore, paragraph (h)(4) of this AD has been revised to only require 
reporting inspection results to the OEM.

Request To Specify AMM Task for Oxygen Generator Replacement

    Delta requested that an exception be added to specify the 
applicable AMM task required to replace affected generators for oxygen 
container/generator removal and installation. Paragraph (1) of EASA AD 
2023-0209 specifies replacing affected parts in accordance with the 
instructions of the AOT. The AOT referenced in EASA AD 2023-0209 
requires in paragraph 5.6 that operators remove and replace the 
affected oxygen generator in accordance with Collins Aerospace Service 
Bulletin XXCXX-35-001, dated October 6, 2023, and AMM instructions for 
removal/installation of the emergency oxygen generators. Because both 
instructions are required for compliance, and because the instructions 
do not provide the exact same instructions, Delta stated it is 
difficult to determine which instructions to follow. Delta asserted 
that AMM tasks for removing the affected units provide standard 
practices to effectively replace the oxygen generator, and no 
additional instructions from the Collins service bulletin are 
necessary. Additionally, many operators, including Delta, have 
supplemental type certificates (STCs) for interior modifications that 
might involve replacing the oxygen container with an oxygen panel or 
some other part label. These STCs will have separate instructions from 
those called out in the AOT, but they can still contain affected oxygen 
generators and therefore must be inspected.
    The FAA agrees with the request, for the reasons provided by the 
commenter. The replacement required by this AD can be done using the 
applicable AMM task for oxygen container/generator removal and 
installation. The FAA has added paragraph (h)(4) to this AD to specify 
that where the service information referenced in EASA AD 2024-0198 
specifies a method of compliance for removal and installation of the 
oxygen container/generator in accordance with the service information 
or aircraft maintenance manual, for this AD, either method is 
acceptable.

Request To Clarify Mandatory RC Steps

    Paragraph (1) of EASA AD 2023-0209 specified replacing affected 
parts in accordance with ``the instructions of the AOT,\3\'' but the 
exception in paragraph (h)(2) of the proposed AD specified replacing 
affected parts in accordance with ``paragraph 5.6 of the AOT.'' Because 
paragraphs 5.1, 5.4, 5.5, and 5.6 of the AOT are RC (required for 
compliance), Delta noted a potential conflict in paragraph (i)(3) of 
the proposed AD, which stated ``if any service information referenced 
in EASA AD 2023-0209 contains paragraphs that are labeled as RC, the 
instructions in RC paragraphs, including subparagraphs under an RC 
paragraph, must be done to comply with this AD.'' Delta therefore 
requested that the proposed AD clarify whether only paragraph 5.6 of 
the AOT would be required, or whether paragraphs 5.1, 5.4, and 5.5 are 
would also be required.
---------------------------------------------------------------------------

    \3\ EASA AD 2023-0209 defines the AOT as Airbus All Operators 
Transmission (AOT) A35L021-23, AOT A35N020-23, and AOT A35W022-23, 
all dated October 10, 2023.
---------------------------------------------------------------------------

    The FAA provides the following clarification. The FAA acknowledges 
that paragraph (i)(3) of the proposed AD should also have included an 
exception to paragraph (h)(2) of the proposed AD

[[Page 8887]]

(paragraph (h)(3) in this AD). The FAA has revised paragraph (i)(3) of 
this AD accordingly.

Request for Revised/Alternative Identification Criteria

    Delta requested that an exception be added to the proposed AD to 
allow operators to identify affected units by the part number (PN) and 
date of manufacture, instead of the part number and serial number as 
specified in EASA AD 2023-0209. EASA AD 2023-0209 defines an affected 
part as ``any chemical oxygen generator having part number (PN) E63320-
00, PN E63340-00 or PN E63440-00 and a serial number (SN) BEBJF002-XXX, 
BEBJ-F007-XXX, BEBJ-F008-XXX or BEBJ-F011-XXX (where `XXX' represents 
any numerical sequence and is the specific number of this generator).'' 
Delta stated that Collins Aerospace, Airbus, and EASA have verified 
that the list of affected oxygen generator part numbers and serial 
numbers correspond to units manufactured in 2010. Delta asserted that 
chemical oxygen generators are life limited by the FAA and therefore 
tracked based on the date of manufacture. Therefore, Delta requested 
using the conservative criterion of the date of manufacturer to 
identify affected oxygen generators.
    The FAA disagrees with the request. The FAA has found no clear 
correlation between the date of manufacture and the OEM's serial 
number. Therefore, to ensure that all affected units are correctly 
identified, operators must use serial numbers, as specified in EASA AD 
2024-0198.

Request To Clarify Serviceable Parts

    Delta requested that an additional exception be added to the 
proposed AD to further clarify parts eligible for installation, using 
the EASA AD definition of serviceable part: ``any oxygen generator, 
eligible for installation, which is not an affected part.'' Delta 
noted, however, that paragraph 5.6 of the AOT requires that an affected 
generator be replaced by an unaffected oxygen generator ``with the same 
PN,'' with no requirement that it should not be an affected part and 
restricting it to the same part number.
    The FAA agrees with the request. The FAA has revised paragraph 
(h)(3) of this AD to specify to replace each affected part with an 
oxygen generator, eligible for installation, which is not an affected 
part.

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 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.

Material Incorporated by Reference Under 1 CFR Part 51

    EASA AD 2024-0198 specifies procedures for replacing affected 
oxygen generators, which includes reporting and returning affected 
parts to the manufacturer. EASA AD 2024-0198 also prohibits the 
installation of affected parts. 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.

Costs of Compliance

    The FAA estimates that this AD affects 1,975 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this 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 currently 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

    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:

[[Page 8888]]

    (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.

(d) Subject

    Air Transport Association (ATA) of America Code 35, Oxygen.

(e) Unsafe Condition

    This AD was prompted by reported occurrences of chemical oxygen 
generators failing to activate in service and during maintenance 
activities. The FAA is issuing this AD to address poor reactivity of 
the start powder used inside the affected oxygen generators. The 
unsafe condition, if not addressed, could lead to a reduction of the 
available oxygen capacity of the airplane and could result in injury 
to airplane occupants.

(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 
2024-0198, dated October 18, 2024 (EASA AD 2024-0198).

(h) Exceptions to EASA AD 2024-0198

    (1) Where EASA AD 2024-0198 refers to December 6, 2023 (the 
effective date of EASA AD 2023-0209, dated November 22, 2023), this 
AD requires using the effective date of this AD.
    (2) Where EASA AD 2024-0198 refers to its effective date, this 
AD requires using the effective date of this AD.
    (3) Where paragraph (1) of EASA AD 2024-0198 specifies to 
``replace each affected part with a serviceable part in accordance 
with the instructions of the AOT,'' this AD requires replacing that 
text with ``replace each affected part with an oxygen generator, 
eligible for installation, which is not an affected part, in 
accordance with paragraph 5.6 of the AOT.''
    (4) Where the service information referenced in EASA AD 2024-
0198 specifies a method of compliance for removal and installation 
of the oxygen container/generator in accordance with the service 
information or aircraft maintenance manual, for this AD, either 
method is acceptable.
    (5) The service information referenced in EASA AD 2024-0198 
specifies to report inspection results to Airbus and return affected 
oxygen generators to Collins Aerospace. For this AD, reporting 
inspection results is required at the applicable time specified in 
paragraph (h)(5)(i) or (ii) of this AD, but returning affected 
oxygen generators to Collins Aerospace is not required by this AD.
    (i) If the affected oxygen generator was replaced on or after 
the effective date of this AD: Submit the report within 40 days 
after the replacement.
    (ii) If the affected oxygen generator was replaced before the 
effective date of this AD: Submit the report within 40 days after 
the effective date of this AD.
    (6) This AD does not adopt the ``Remarks'' section of EASA AD 
2024-0198.

(i) Additional AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, AIR-
520, Continued Operational Safety 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 manager of 
the Continued Operational Safety Branch, mail it to the address 
identified in paragraph (j) 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, AIR-520, 
Continued Operational Safety Branch, FAA; or EASA; or 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 
paragraphs (h)(3), (h)(4), and (i)(2) of this AD, if any service 
information referenced in EASA AD 2024-0198 contains paragraphs that 
are labeled as RC, the instructions in RC paragraphs, including 
subparagraphs under an RC paragraph, must be done to comply with 
this AD; any paragraphs, including subparagraphs under those 
paragraphs, that are not identified as RC are recommended. The 
instructions in paragraphs, including subparagraphs under those 
paragraphs, 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 
instructions identified as RC can be done and the airplane can be 
put back in an airworthy condition. Any substitutions or changes to 
instructions identified as RC require approval of an AMOC.
