from the Office of Research and Engineering and the Office of Aviation Safety conducted
an audition of the CVR as part of the NTSB’s ongoing investigation of the accident.
The audition revealed the following information, which is preliminary and
subject to change as the investigation continues:
The flight data recorder arrived at the NTSB’s Recorder Lab Sunday at 11:45 p.m. The memory module was disassembled, cleaned and dried, and download of the data was achieved Monday afternoon. Initial review of the data revealed:
The accident flight was captured, and the FDR contained a total of about 54 hours of data from 17 flights.
There were approximately 350 parameters recorded by the FDR detailing the motion of the aircraft and operation of its engines, flight controls and other systems.
recorder investigators are currently verifying and validating the FDR data, and
the NTSB plans to provide a summary in an investigative update in a few days.
experts in the CVR group will convene in the coming week to review the entire
recording and produce a transcript of the accident recording. It will be a time-consuming
process to complete the transcript.
The CVR group
is one of the seven investigative groups established by the
Investigator-in-Charge for the accident investigation.
