NTSB Report Reveals Medical Jet's Voice Recorder Was Nonfunctional Before Fatal Philly Crash

The January crash killed seven people and injured at least 24, with investigators still probing the cause of the rapid descent.

The cockpit voice recorder retrieved from the crashed Learjet 55 in Philadelphia was found to be nonfunctional and likely had not recorded audio for years, according to the NTSB's preliminary report.
The January 31 crash killed all six people on board, including an 11-year-old girl and her mother, as well as one person on the ground, leaving 24 others injured and causing significant damage to homes and businesses.
Investigators confirmed no distress calls were made by the crew during the flight, which lasted less than a minute before the aircraft descended rapidly and exploded on impact in a residential area.
The crash left a 1,400-foot debris field and destroyed or damaged multiple properties, with injuries on the ground including severe burns and trauma caused by flying debris.
An Enhanced Ground Proximity Warning System from the aircraft, which may contain critical flight data, is currently being evaluated by its manufacturer for potential recovery of information.
