The NTSB's narrative final · quoted from the NTSB record
DURING A VISUAL APPROACH TO THE AIRPORT, THE TOWER CONTROLLER NOTICED THAT THE AIRPLANE WAS HIGH, AND INSTRUCTED THE PILOT TO GO AROUND AND ENTER A RIGHT DOWNWIND. REPEATED INSTRUCTIONS TO TURN TO DOWNWIND BROUGHT NO RESPONSE UNTIL A TURN WAS FINALLY INITIATED. AT THAT TIME THE PILOT DECLARED AN EMERGENCY, REPORTING THAT HE WAS HOLDING FULL BACK ELEVATOR, TRYING TO KEEP THE AIRPLANE IN THE AIR, AND THAT IT LOOKED LIKE HIS ELEVATORS WERE STUCK. THE AIRPLANE CONTINUED AWAY FROM THE AIRPORT AND ENTERED A NEAR VERTICAL HIGH SPEED DESCENT INTO A STORAGE BUILDING. INVESTIGATION REVEALED BOTH ELEVATOR TRIM ACTUATORS AT A 4 DEG NOSE DOWN TRIM POSITION, AND EVIDENCE INDICATES A 40 DEG DOWN ELEVATOR POSITION. NO MALFUNCTION OF THE ENGINES OR FLIGHT CONTROLS WERE FOUND. THE AUTOPILOT SYSTEM CONTROL MODULE WAS DESTROYED. THE PILOT HAD RECEIVED 7 HOURS OF TRAINING IN THE AIRPLANE, AND HAD 20 HOURS TOTAL TIME IN THE AIRPLANE.
