The Federal Aviation Administration (FAA) has issued a final rule for Airbus SAS airplanes, specifically models A318, A319, A320, and A321. This new rule is in response to laboratory tests highlighting issues with the lithium batteries in the emergency locator transmitters (ELTs) of these planes, which could lead to thermal runaway and battery fires. The rule mandates the installation of a diode to prevent this unsafe condition, addressing potential risks of local fires, airplane damage, and injuries to occupants. This directive ensures that all affected aircraft are compliant by a specific deadline and includes provisions for technical adaptations and modifications to existing equipment.
Simple Explanation
The FAA made a new rule for certain Airbus planes because a part that's supposed to help find the plane if it gets lost might catch fire. They are making sure a special piece will be added to stop the fire from happening, keeping everyone safe.
