Analysis

The crew was executing the ILS approach and had turned back inbound on the procedure turn to the outer marker when the co-pilot stated they were 5.9 DME in a calm voice with no indication of a problem. Impact with the ground occurred at about 5.9 DME, approximately 10 statute miles from the airport, while the aircraft was in a slight noseup, slight right wing down attitude, with a high vertical rate of descent, and a high forward speed. The aircraft was demolished. No evidence of a pre-impact failure or malfunction of the aircraft or its systems could be found. The copilot was not rated in the aircraft and had logged a total of 7.9 hours of jet time in his personal logbook.
