Rule
Summary
The FAA is setting new safety rules for Honeywell’s installation of non-rechargeable lithium batteries in Boeing 757 airplanes’ underwater locator beacons. These special conditions make sure the batteries meet modern safety standards since current rules don’t cover this new tech. The rules take effect April 16, 2026, and Honeywell must follow them to keep flights safe without extra costs for airlines.
