What was found
LDC873FT AILERON WAS REMOVED FOR OTHER MAINTENANCE. WITH THE AILERON REMOVED IT WAS DISCOVERED THAT THE BEARING MOUNTED IN THE ROLL TRIM MOTOR ASSY. (P/N-12546-001) WAS LOOSE. THIS BEARING IS INSTALLED WITH A LIQUID LOCKING PRODUCT AND SUBJECTED TO A LOAD TEST PRIOR TO INSTALLATION. IT IS NOT KNOWN HOW THIS BEARING COULD HAVE COME LOOSE. IT IS VERY DIFFICULT TO INSPECT THIS INSTALLATION WITH THE AILERON INSTALLED. THIS BEARING SHOULD BE INSTALLED ANY TIME THE LEFT AILERON IS REMOVED.
