Read the full NTSB narrative

During a descent in preparation for landing, the left wing of the airplane experienced an uncommanded aileron trim input to the up position. Attempts to raise the right wing through the use of the roll trim select switch were unsuccessful on both the pilot and copilot sides of the airplane. The left wing continued to trim up until the left and right trim tabs were fully deflected in opposite directions requiring both pilots to physically control the airplane with full left control column input. The pilots declared an emergency and as airspeed was reduced, controllability improved and an uneventful landing was made. Examination of the roll trim control printed circuit board revealed that the relays on the board had developed a 'time lag,' causing them to stick in the closed position. As of the date of this report, the manufacturer was in the process of redesigning the circuit board.
