What was found
DURING THE TECHNICIAN'S DAILY INSPECTION, THE LEFT POSITION LIGHT ASSEMBLY WAS FOUND TO BE INOPERATIVE, WHICH WAS INSTALLED 4.7 FLIGHT HOURS EARLIER DUE TO FAILURE. UPON INSPECTION, IT WAS FOUND THAT ONE OF THE SCREWS WHICH SECURES THE LIGHT DEFLECTOR CAME LOOSE AND MIGRATED WITHIN THE LIGHT ASSEMBLY DURING FLIGHT, SHORTING OUT THE INTERNAL CIRCUIT BOARD. THE POSITION LIGHT ASSEMBLY WAS REMOVED AND UPON INSTALLATION OF THE NEW ASSEMBLY, THE SAME DEFLECTOR SCREWS WERE FOUND TO BE LOOSE OUT OF THE BOX. THE SCREWS WERE TORQUED AND THE LIGHT ASSEMBLY INSTALLED WITH NO FURTHER ISSUE.
