Jet crashes into Philadelphia residential area at high speed

NTSB has just issued its preliminary report for its ongoing investigation of the Jan. 31 crash. 4 pages long, it summarises what's been already more or less known, including pilots' qualification details and - what's new - the result of the CVR reading:

The airplane was equipped with a cockpit voice recorder (CVR). The CVR was recovered from the initial impact crater under 8 ft of soil and debris and was sent to the NTSB Vehicle Recorders Laboratory, Washington, DC, for processing and readout. The recorder displayed significant impact-related damage as well as liquid ingress. After extensive repair and cleaning, the 30-minute-long tape-based recording medium was auditioned to determine its contents. The CVR did not record the accident flight and during the audition it was determined that the CVR had likely not been recording audio for several years.

The evaluation of the EGPWS by the manufacture's facility was still ongoing at the time of writing of the report.
