Gulfstream's Cozy Oxygen Sharing: FAA Issues Special Safeguards
Published Date: 3/17/2026
Rule
Summary
The FAA is setting new safety rules for Gulfstream’s G300 airplane because it’s adding a special oxygen system that shares oxygen between pilots and passengers. These new rules make sure this cool feature is just as safe as other airplane systems. The rules take effect on March 17, 2026, and Gulfstream and anyone interested can send comments by May 1, 2026.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 1 costs, 0 mixed.
Shared Oxygen Systems Must Preserve Crew Supply
For the Gulfstream Model G300, if the airplane uses a shared oxygen source for both crew and passengers, the oxygen distribution system must either have separate sources for supplemental and therapeutic oxygen or use a common source with a way to separately reserve the minimum oxygen supply required by passengers for supplemental use after a loss of cabin pressure. This special condition applies to the Model G300 and took effect March 17, 2026.
Requirement Also Applies to Other Models with Same Feature
These special conditions are initially applicable to the Gulfstream Model G300 but will also apply to any other model on the same type certificate, or to any model later added to that type certificate, if it incorporates the same shared therapeutic oxygen design feature.

2026-16795, Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737 -300, -400, and -500 series airplanes. This proposed AD was prompted by reports of nuisance stick shaker activation while accelerating to cruise speed at the top of a climb due to frozen angle of airflow (AOA) sensor vanes. This proposed AD would require installing new external case heaters (ECHs) on the left and right AOA sensors, performing repetitive functional tests and applicable corrective actions, and accomplishing applicable concurrent actions. The FAA is proposing this AD to address the unsafe condition on these products.
