The NTSB is aware that advances in image recognition and computational methods have enabled individuals to reconstruct approximations of cockpit voice recorder audio from sound spectrum imagery released as part of NTSB investigations, including the ongoing investigation of the crash last year of UPS flight 2976 in Louisville, Kentucky.
The NTSB does not release cockpit audio recordings. Federal law prohibits such public release due to the highly sensitive nature of verbal communications inside the cockpit. The NTSB takes these privacy restrictions seriously.
The NTSB docket system is temporarily unavailable as we examine the scope of the issue and evaluate solutions. We hope to restore access to the docket system as soon as possible.
