Probable cause
The NTSB’s determination of the probable cause, and any contributing factors.
The total failure of the flight compartment windshield (copilot's side) for undetermined reasons.
Analysis
During cruise flight at flight level 190, the copilot's windshield failed causing rapid decompression. The captain declared an emergency and landed the aircraft without incident. Portions of the remaining windshield were analyzed. The windshield was properly installed and no reason for the failure could be determined.
