FAA Rules Require Replacing Faulty Airplane Oxygen Masks
Published Date: 2/25/2026
Rule
Summary
The FAA is making a new rule to fix a problem with certain Aerospace & Defense Oxygen Systems SaS portable breathing equipment (PBE) that sometimes don’t deliver oxygen when needed. If you use this gear, you’ll have to replace the faulty units and can’t install the old ones anymore. This rule kicks in on March 12, 2026, and the FAA wants your feedback by April 13, 2026.
Analyzed Economic Effects
3 provisions identified: 0 benefits, 3 costs, 0 mixed.
Mandatory PBE Replacement and Ban
If your aircraft has Aerospace & Defense Oxygen Systems SaS portable breathing equipment (PBE) part number 15-40F-11 or 15-40F-80 with a manufacturing date between March 2015 and March 2017 and a serial number listed in Appendix A of Safran Service Bulletin 1540F-35-002 Revision 01, you must replace those units. The rule also prohibits installing the affected PBE; the AD is effective March 12, 2026 and the FAA will accept comments through April 13, 2026.
Estimated Compliance Cost Per Unit
The FAA estimates replacement will cost up to $2,585 per PBE (1 work-hour at $85 plus up to $2,500 for parts). The FAA estimates up to 2,642 appliances are affected and estimates a total cost on U.S. operators of up to $6,829,570.
10-Year Life Limit Takes Precedence
The affected PBE have a life limit of 10 years (120 months), and that life limit takes precedence over the shorter compliance windows (14 days or 3 months) in the referenced EASA AD. If an affected PBE is over the 10-year life limit, it must be replaced regardless of those shorter compliance times.
