Key Takeaways:

The National Transportation Safety Board (NTSB) discovered that artificial intelligence (AI) is being used to reconstruct cockpit voice recorder (CVR) audio from sound spectrum imagery released in their investigation dockets, including for the ongoing probe of the 2025 UPS Flight 2976 crash.
Federal law prohibits the public release of CVR audio due to its highly sensitive nature, a privacy restriction the NTSB takes seriously.
In response to the AI reconstruction issue, the NTSB temporarily made its docket system unavailable to examine the scope of the problem and evaluate solutions.

When the National Transportation Safety Board releases an accident investigation docket, it often contains a transcript of the conversations captured on the cockpit voice recorder (CVR)— but never the actual recording.

Yet on Thursday the NTSB announced it had become aware of someone using artificial intelligence (AI) to reconstruct approximations of CVR audio from sound spectrum imagery released as part of the agency’s investigations, including the ongoing probe of the 2025 crash of UPS Flight 2976 in Louisville, Kentucky.
