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 in its investigation dockets.
This practice violates federal law prohibiting the public release of CVR recordings, prompting the NTSB to temporarily take its public docket system offline to examine the issue's scope and implement 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.
