Abstract
The FAA is superseding Airworthiness Directive (AD) 2025-25- 02, which applied to all aircraft equipped with certain Aerospace & Defense Oxygen Systems SaS portable breathing equipment (PBE). AD 2025- 25-02 required incorporating revised procedures for donning the PBE. Since the FAA issued AD 2025-25-02, the agency determined the unsafe condition may be addressed by incorporating the updated procedures into documentation that is not identified in AD 2025-25-02 and that certain requirements in AD 2025-25-02 must be revised. This AD requires incorporating updated procedures for donning the PBE. The FAA is issuing this AD to address the unsafe condition on these products.

Background
The FAA issued Airworthiness Directive 2025-25-02, Amendment 39-
23210 (90 FR 56990, December 9, 2025) (AD 2025-25-02), for all aircraft
equipped with certain Aerospace & Defense Oxygen Systems SaS PBE. AD
2025-25-02 was prompted by an MCAI originated by the European Union
Aviation Safety Agency (EASA), which is the Technical Agent for the
Member States of the European Union. EASA issued AD 2025-0222, dated
October 13, 2025 (EASA AD 2025-0222) (also referred to as the MCAI), to
correct an unsafe condition. The MCAI states that occurrences of
incorrect usage of PBE have been reported. This condition, if not
corrected, could lead to flight or cabin crewmember incapacitation,
possibly affecting crewmember capability to accomplish tasks during an
emergency, or resulting in fatal injury to that crewmember. Relevant
investigations identified that the PBE operational manual provides
instructions that can be misunderstood by a flight or cabin crewmember,
possibly leading to errors while donning the PBE.
AD 2025-25-02 required incorporating revised procedures for donning
PBE, part number (P/N) 15-40F-11 and P/N 15-40F-80, into the existing
maintenance or inspection program, as applicable (for transport
category airplanes); into maintenance records (for non-transport
category aircraft that must comply with 14 CFR 91.417(a)(2) or
135.439(a)(2)); or into the existing approved maintenance or inspection
program, as applicable (for other non-transport category airplanes).
The revised procedures for the proper
[[Page 61051]]
donning of PBE P/N 15-40F-11 and P/N 15-40F-80 prevent adverse effects
from non-activation of the oxygen system, with additional warnings
against inserting hands into the packaging and ensuring only the black
neck seal is grabbed to avoid damage. The donning process includes
detailed steps on deploying the hood and emphasizes the importance of
hearing the oxygen flow noise immediately after donning.
AD 2025-25-02 specified that, for non-transport category aircraft,
the owner/operator (pilot) holding at least a private pilot certificate
may perform the required action for that aircraft provided compliance
with the applicable paragraph of the AD is entered into the aircraft
maintenance records in accordance with 14 CFR 43.9(a) and
91.417(a)(2)(v). AD 2025-25-02 stated that the pilot may perform this
action because it only involves incorporating revised procedures for
donning the PBE and that this action could be performed equally well by
a pilot or a mechanic. AD 2025-25-02 noted that this is an exception to
the FAA's standard maintenance regulations.
The FAA issued AD 2025-25-02 to address the unsafe condition on
these products.
Actions Since AD 2025-25-02 Was Issued
Since the FAA issued AD 2025-25-02, the FAA determined the unsafe
condition may be addressed by incorporating updated procedures into
documentation that is not identified in AD 2025-25-02 and that certain
requirements in AD 2025-25-02 must be revised. The FAA has revised the
requirements in paragraph (g) of this AD and added optional methods of
compliance to paragraph (h) of this AD.
The FAA is issuing this AD to address the unsafe condition on these
products.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2025-5400.
Comments on AD 2025-25-02
The FAA issued AD 2025-25-02 as a final rule; request for comments.
The FAA received numerous comments on AD 2025-25-02 asking for clarity
on how to comply with the AD or requesting that the FAA revise the
requirements. Commenters questioned the requirement to revise the
maintenance or inspection program, including the requirement to replace
pictograms, and asked whether revising operation manuals (end user
instructions) are acceptable methods of compliance.
Aeromexico, Air Astana, Allegiant Air, China Airlines, Commuteair,
and Netjets stated that the AD requires revising the maintenance or
inspection program as specified in 3.C., ``Procedure,'' of Safran
Aerosystems Service Bulletin 1540F-35-001, dated October 10, 2025.
Aeromexico and Air Astana noted that those procedures look to be for
the flightcrew or apply more to flightcrew operational manual (FCOM)
and operational manual (OM-E) for cabin crew. Allegiant Air stated the
existing maintenance or inspection program revision does not apply to
flightcrews and their procedures. China Airlines noted there are
currently no maintenance or inspection procedures related to the PBE
donning procedure and asked what steps are needed to implement this AD
requirement.
Commuteair stated the maintenance and inspection programs for the
PBEs do not include requirements for donning or using the PBE masks.
Commuteair noted the appropriate manuals for inclusion of the updated
pictograms would be related to flight operations manuals, inflight
manuals and training materials for flightcrew and flight attendants for
PBE usage. Netjets asked the FAA to clarify the basis on which these
donning operational procedures should be incorporated into the
maintenance program for MSG-3 covered aircraft. Netjets also asked if
there is a recommended recurrent interval for it to be included into
the maintenance program.
Aeromexico asked if the inclusion of the aircraft operations manual
(AOM) can be considered a method of compliance to AD 2025-25-02.
Aeromexico noted the same procedures for the PBE are included in the
AOM and including a copy of this can be considered as a correct way to
give more security during the donning of the PBE. Aeromexico considered
that including the procedures in the airplane flight manual (AFM) or
the AOM, gives more value than to include them into the maintenance
program or the inspection manuals.
Allegiant Air asked if it would be more accurate to require the
revision of the FCOM and/or cabin crew operating manual (CCOM) to
incorporate the specific instructions from the vendor service bulletin
since they are the end users of the PBEs.
AMES-CAMO stated it does not understand why the aircraft
maintenance program should be updated. AMES-CAMO stated the procedures
in the service bulletin are purely operational procedures and are not
maintenance procedures. AMES-CAMO noted that paragraph (2) of EASA AD
2025-0222 provides an acceptable method of compliance, which allows
updating the operations manual of the aircraft instead of the
maintenance program. AMES-CAMO asked if an amendment of the operations
manual of the aircraft satisfies the requirement of paragraph (g) of
FAA AD 2025-25-02.
Japan Airlines requested that the requirements in paragraph (g) of
AD 2025-25-02 be corrected because the procedures relate to the
operation steps of the PBE and, therefore, should be reflected in the
operation manual or the instructions to flight and cabin crewmembers.
Turkish Airlines stated it has revised the operational manuals
(FCOM and/or CCOM) according to Safran Aerosystems Service Bulletin
1540F-35-001, dated October 10, 2025, and asked if that meets the AD
2025-25-02 requirements. Turkish Airlines stated that if it does not
meet the AD 2025-25-02 requirements, then the FAA should clarify what
are the transport category airplane operators' required actions to
comply this AD's requirements.
Swift Air stated its fleet has already complied with EASA AD 2025-
0222 by applying both methods of compliance: updating the operations
manual in accordance with Safran Aerosystems Service Bulletin 1540F-35-
001, dated October 10, 2025, and providing the corresponding crew
training.
Tibet Airlines stated that in order to comply with the requirements
of EASA AD 2025-0222, Tibet Airlines has issued technical/business
notices in accordance with Section 3.C., ``Procedures,'' of Safran
Aerosystems Service Bulletin 1540F-35-001, dated October 10, 2025.
Tibet Airlines asked if the incorporation of the revised procedures
specified in Section 3.C. ``Procedures,'' of Safran Aerosystems Service
Bulletin 1540F-35-001, dated October 10, 2025, through the above-
mentioned approach is acceptable to comply with the requirements of AD
2025-25-02.
Stark Airways stated they cannot find on this AD what exactly to do
and asked for some clarification.
Air France, Allegiant Air, HNA Technic, and Safran Aerosystems
stated Safran Aerosystems Service Bulletin 1540F-35-001, dated October
10, 2025, does not include instructions for replacing pictograms. Air
France stated its understanding is that the AD concerns operational
flight procedures and that there is no work to be done on aircraft.
Allegiant Air noted that after reviewing the component maintenance
manual (CMM) for P/N 15-40F-80, the pictogram decal pictured on the PBE
case matches the pictograms in figures 3 and 4 of Safran Aerosystems
Service
[[Page 61052]]
Bulletin 1540F-35-001, dated October 10, 2025. HNA Technic stated that
after receiving EASA AD 2025-0222, they thought pictograms of PBE
should be replaced, but noted that Safran did not agree with their
opinion. Safran Aerosystems asked for the reason of the FAA requirement
or if it is a mistake. Swift Air stated they consulted Safran about
whether any action is required on the lid of the PBE packaging box, and
that Safran confirmed to them that no modification to the packaging box
was required.
The FAA agrees that the requirement to revise the maintenance or
inspection is not necessary in order to address the unsafe condition.
The intent of this AD is to ensure updated procedures for donning the
PBE are incorporated into applicable documentation for the intended
user. The FAA has revised the requirements in paragraph (g) of this AD
and added optional methods of compliance to paragraph (h) of this AD.
Material Incorporated by Reference Under 1 CFR Part 51
This AD requires Safran Aerosystems Service Bulletin 1540F-35-001,
dated October 10, 2025, which the Director of the Federal Register
approved for incorporation by reference as of December 24, 2025 (90 FR
56990, December 9, 2025).
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 civil aviation authority
of another country and are approved for operation in the United States.
Pursuant to the FAA's bilateral agreement with this State of Design
Authority, that authority has notified the FAA of the unsafe condition
described in the MCAI and material referenced above. The FAA is issuing
this AD after determining that the unsafe condition described
previously is likely to exist or develop on other products of the same
type design.
AD Requirements
This AD requires incorporating updated procedures for donning
certain PBE as specified in paragraph 3.C., ``Procedure,'' of Safran
Aerosystems Service Bulletin 1540F-35-001, dated October 10, 2025. This
AD also specifies the following optional methods of compliance for
incorporating updated procedures.
<bullet> Amend the operation manual(s), as applicable, of an
aircraft by incorporating updated instructions for donning PBE P/N 15-
40F-11 and P/N 15-40F-80 as specified in paragraph 3.C., ``Procedure,''
of Safran Aerosystems Service Bulletin 1540F-35-001, dated October 10,
2025.
<bullet> Disseminate the content of the updated instructions
specified in paragraph 3.C., ``Procedure,'' of Safran Aerosystems
Service Bulletin 1540F-35-001, dated October 10, 2025, to all flight
and cabin crewmembers of an aircraft.
Justification for Immediate Adoption and Determination of the Effective
Date
Section 553(b) of the Administrative Procedure Act (APA) (5 U.S.C.
551 et seq.) authorizes agencies to dispense with notice and comment
procedures for rules when the agency, for ``good cause,'' finds that
those procedures are ``impracticable, unnecessary, or contrary to the
public interest.'' Under this section, an agency, upon finding good
cause, may issue a final rule without providing notice and seeking
comment prior to issuance. Further, section 553(d) of the APA
authorizes agencies to make rules effective in less than thirty days,
upon a finding of good cause.
An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies forgoing notice and comment prior to adoption of this rule
because incorrect usage of PBEs could lead to flight or cabin
crewmember incapacitation, possibly affecting crewmember capability to
accomplish tasks during an emergency, or resulting in fatal injury to
that crewmember. The PBEs are designed to protect the user's eyes and
respiratory tract in a contaminated atmosphere, which provides the
ability to locate and combat a fire. Additionally, the compliance time
in this AD is shorter than the time necessary for the public to comment
and for publication of the final rule. Accordingly, notice and
opportunity for prior public comment are impracticable and contrary to
the public interest pursuant to 5 U.S.C. 553(b).
In addition, the FAA finds that good cause exists pursuant to 5
U.S.C. 553(d) for making this amendment effective in less than 30 days,
for the same reasons the FAA found good cause to forgo notice and
comment.
Regulatory Flexibility Act
The requirements of the Regulatory Flexibility Act (RFA) do not
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt
a rule without prior notice and comment. Because FAA has determined
that it has good cause to adopt this rule without prior notice and
comment, RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD affects approximately 80,000
appliances installed on but not limited to transport category
airplanes. The FAA estimates the following costs to comply with this
AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per
Labor cost Parts cost product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85........ $0 $85 Up to $6,800,000.*
----------------------------------------------------------------------------------------------------------------
* It is unknown how many of the 80,000 appliances are installed on U.S.-registered aircraft.
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.
[[Page 61053]]
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, and
(2) Will not affect intrastate aviation in Alaska.
