What was found
WHILE TROUBLESHOOTING A FAULTY ANTI-COLLISION LIGHT THE MAINTENANCE TECHNICION FOUND THE LOWER ANTI-COLLISION LIGHT MOUNT BRACKET LOOSE AND SMOKING AT THE TWO FORWARD SCREWS. THIS BRACKET PN 109-0371-60-109 IS MOUNTED ON THREE RUBBER SHOCKMOUNTS. A NEW MOUNT WAS ORDERED, AND IT WAS DETERMINED THAT THE COUNTER SUNK SCREW THREADS WERE BOTTOMING OUT IN THE SHOCKMOUNTS BEFORE PROPER CLAMP-UP OF THE MOUNT COULD BE ACHIEVED. HAD THIS CONDITION CONTINUED, THE MOUNT WOULD HAVE CHAFED THROUGH POSSIBLY ALLOWING THE ANTICOLLISION LIGHT TO DEPART THE AIRCRAFT. THIS CONDITION WAS ELIMINATED BY ADDING A NAS1149FN623P WASHER BETWEEN THE SHOCKMOUNT AND THE MOUNT BRACKET.
