Mountain High Equipment & Supply secured FAA NORSEE approval for its EDS-305X Series O2D2 oxygen systems. This designation allows the equipment to be installed as a minor alteration on qualifying aircraft certificated under 14 CFR Part 23.
Why it matters
The NORSEE, or Non-Required Safety Enhancing Equipment, policy is designed to lower barriers for manufacturers and owners to integrate safety-focused technology into general aviation aircraft. By granting this approval, the FAA provides a streamlined path for pilots to improve cabin safety.
The FAA NORSEE approval applies specifically to the EDS-305X Series O2D2 oxygen systems for aircraft certificated under 14 CFR Part 23. Installations may qualify as minor alterations if they strictly adhere to the conditions outlined in the FAA authorization.
The players
Mountain High Equipment & Supply

Federal Aviation Administration
The national aviation authority of the United States that oversees civil aviation and sets safety standards.
The details
This approval allows owners of 14 CFR Part 23 aircraft to install the oxygen systems with reduced regulatory friction if specific safety conditions are met. Systems that do not meet the criteria for minor alterations will still require FAA-approved data for major alteration status.
Timeline
The FAA granted the NORSEE approval to Mountain High Equipment & Supply on September 20, 2026.
Travel Outlook
The NORSEE policy represents an ongoing effort by regulators to modernize safety standards without imposing the heavy administrative burdens of traditional certification paths. This move positions the equipment as a viable, accessible upgrade for the general aviation fleet.
Aircraft owners can now potentially reduce installation costs and regulatory paperwork by utilizing this approved equipment. Pilots should consult with their maintenance technician to verify if their specific aircraft configuration qualifies for a minor alteration under the new authorization.
The takeaway
Voluntary safety enhancements can provide significant protection for general aviation occupants without the need for extensive regulatory overhauls. Owners are encouraged to verify eligibility requirements with authorized maintenance professionals before proceeding with installations.
