Airworthiness Directive · Amendment 39-23210 · Oxygen
Aerospace & Defense Oxygen Systems SaS (Part of Safran Aerosystems) (Formerly Known as Air Liquide)
Superseded. A later AD replaced this one: AD 2025-26-06. Comply with the one in force.
This AD applies to Aerospace & Defense Oxygen Systems SaS (part of Safran Aerosystems) (formerly known as Air Liquide) portable breathing equipment (PBE), part number (P/N) 15-40F-11 and P/N 15-40F-80, all serial numbers. These PBEs are eligible for installation on any aircraft and may have been installed during the aircraft manufacturing process (production line), or in-service modification, either through a supplemental type certificate, or using type certificate holder (TCH) approved modification instructions, or through a non-TCH modification approval.
The FAA is adopting a new airworthiness directive (AD) for all aircraft equipped with certain Aerospace & Defense Oxygen Systems SaS portable breathing equipment (PBE). This AD was prompted by reports of occurrences of incorrect usage of certain PBEs. This AD requires incorporating revised procedures for donning the PBE. The FAA is issuing this AD to address the unsafe condition on these products.
(1) For transport category airplanes: Within 30 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate revised procedures 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. The incorporation of revised procedures includes replacing the pictograms identified in 3.A., “General,” of Safran Aerosystems Service Bulletin 1540F-35-001, dated October 10, 2025, with the applicable procedure specified in paragraph 3.C., “Procedure,” of Safran Aerosystems Service Bulletin 1540F-35-001, dated October 10, 2025.
(2) For aircraft certificated in any category except for transport category airplanes: Accomplish the applicable action specified in paragraph (g)(2)(i) or (ii) of this AD. The owner/operator (pilot) holding at least a private pilot certificate may perform this action for your aircraft and must enter compliance with the applicable paragraphs of this AD into the aircraft maintenance records in accordance with 14 CFR 43.9(a) and 91.417(a)(2)(v). The record must be maintained as required by 14 CFR 91.417, 121.380, or 135.439.
(i) For aircraft that must comply with 14 CFR 91.417(a)(2) or 135.439(a)(2): Within 30 days after the effective date of this AD, incorporate into maintenance records required by 14 CFR 91.417(a)(2) or 135.439(a)(2), as applicable for your aircraft, revised procedures 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. The incorporation of revised procedures includes replacing the pictograms identified in 3.A., “General,” of Safran Aerosystems Service Bulletin 1540F-35-001, dated October 10, 2025, with the applicable procedure specified in paragraph 3.C., “Procedure,” of Safran Aerosystems Service Bulletin 1540F-35-001, dated October 10, 2025.
(ii) For non-transport category aircraft other than those identified in paragraph (g)(2)(i) of this AD: Within 30 days after the effective date of this AD, revise your existing approved maintenance or inspection program, as applicable, by incorporating revised procedures 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. The incorporation of revised procedures includes replacing the pictograms identified in 3.A., “General,” of Safran Aerosystems Service Bulletin 1540F-35-001, dated October 10, 2025, with the applicable procedure specified in paragraph 3.C., “Procedure,” of Safran Aerosystems Service Bulletin 1540F-35-001, dated October 10, 2025.
After incorporating revised procedures as required by paragraph (g) of this AD, no alternative procedures may be used unless the procedures are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (i)(1) of this AD.
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 manager of the International Validation Branch, send it to the attention of the person identified in paragraph (j) of this AD and email to: AMOC@faa.gov.
