DURING TAKEOFF, THE PLANE WAS OBSERVED TO ROTATE TO A STEEP NOSE HIGH ATTITUDE, THEN ROLL INTO A STEEP BANK, GO INTO A DESCENT, AND CRASH. DURING THE DESCENT, IT ROLLED TO A WINGS LEVEL ATTITUDE BEFORE IMPACTING WITH THE NOSE SLIGHTLY DOWN. AN EXAMINATION OF THE FLIGHT CONTROLS REVEALED NO PREIMPACT MALFUNCTION OR FAILURE EXCEPT THAT THE ELEVATOR TRIM WAS INOPERATIVE. THE ELEVATOR TRIM WAS FOUND IN A NOSE DOWN POSITION. THE OWNER REPORTED THE TRIM BUTTON WAS INOPERATIVE, SO IT WOULD HAVE BEEN SET MANUALLY. THE PILOT'S SEAT FAILED DURING IMPACT.
