FAA proposes to eliminate the prescriptive list of required items in emergency medical kits and first aid kits and replace with a performance based requirement to ensure content are practical and sufficient to allow crewmembers to address the most common emergency illnesses or accidents that occur onboard commercial aircraft. FAA seeks to increase flexibility for air operators while maintaining predictability for airline operators to equip their onboard medical kits. This rule would also update crew training requirements on the use of these kits. This action is necessary to address requirements in the FAA Reauthorization Act of 2024.
