THE PILOT'S LOSS OF CONTROL DUE TO SPATIAL DISORIENTATION WHILE OPERATING IN INSTRUMENT WEATHER CONDITIONS.

Factual narrative

THE FLIGHT HAD DEPARTED RALEIGH DURHAM INTL AIRPORT AT 1119. AT 1122 THE FLIGHT WAS CLEARED TO THE TAR RIVER VOR. THE PILOT 'ROGERED' THE INSTRUCTIONS, AND THIS WAS THE LAST RECORDED CONVERSATION. WITNESSES REPORTED HEARING THE ENGINES REVVING UP BEFORE THE AIRPLANE IMPACTED THE GROUND, AND ONE WITNESS REPORTED SEEING THE AIRPLANE IN A NOSE LOW ATTITUDE BEFORE THE IMPACT. THE PILOT DID NOT REPORT EXPERIENCING WEATHER DIFFICULTIES. THERE WERE NO DEPICTIONS OF THUNDERSTORM ACTIVITY WITHIN THE FLIGHT'S FLIGHT PATH VICINITY ON ATC RADAR. NO PRE-IMPACT FAILURE/MALFUNCTION WAS FOUND. RADAR DATA SHOWED SOME INSTABILITY IN HEADING, ALTITUDE AND AIRSPEED BETWEEN 1120:51 AND 1123:40.
