NTSB Issues Safety Recommendation A-14-116 to FAA Regarding Battery Monitoring Systems
The National Transportation Safety Board directs the Federal Aviation Administration to mandate that type certification applicants demonstrate battery cell temperature limits under extreme conditions.
Safety recommendation
The National Transportation Safety Board directs the Federal Aviation Administration to mandate that type certification applicants demonstrate battery cell temperature limits under extreme conditions.
In safety recommendation A-14-116, identified by NTSB number DCA13IA037, the National Transportation Safety Board has addressed a directive to the Federal Aviation Administration. The board states that once the guidance requested in Safety Recommendation A-14-115 has been issued, the FAA is required to take specific regulatory action. This action involves requiring type certification applicants to demonstrate that their battery monitoring systems maintain each individual cell within safe temperature limits. These demonstrations must occur at the most extreme battery operating temperatures and under the heaviest electrical current loads approved for operation. The recommendation emphasizes the need for rigorous verification of battery safety protocols during the certification process to ensure operational integrity under maximum stress conditions.
