What was found
DURING A WIRING REPAIR TO THE LEFT NAVIGATION LIGHT, A CRACK WAS FOUND UNDER THE VIBRATION DAMPER WEIGHT. NO UNUSUAL VIBRATION HAD BEEN REPORTED PRIOR TO THE CRACK BEING DETECTED. A DAILY INSPECTION OF THE SYNCH ELEVATOR WOULD NOT HAVE REVEALED THIS CRACK, UNTIL THE VIBRATION WEIGHT SEPERATES FROM THE ATTACHING RIB. RECOMMENDED AN INSPECTION BE INCLUDED IN THE MFG INSP PROGRAM TO REMOVE THE SYNCH ELEVATOR TIP CAP AND VISUALLY INSPECT THIS AREA.
