FAA mandates secondary barriers for new aircraft cockpit security.
New airline planes made after mid-2025 will be required to have secondary barriers to the cockpit to make it harder for passengers to break in when the main door is open, according to a new rule by the Federal Aviation Administration. The rule will apply to commercial planes that operate scheduled flights, but not charter operators. The FAA estimated that each secondary barrier will cost $35,000 to buy and install. Pilot unions asked the FAA to extend the requirement for secondary barriers to all airline planes, including older ones.
