## Discrepancy

DURING REPLACEMENT OF AN OPERATIVE LEFT POSITION LIGHT AND STROBE ASSEMBLY DUE TO AN EXTINGUISHED POSITION LIGHT, THE NEW REPLACEMENT PART WAS FOUND TO HAVE AN INOPERATIVE STROBE LIGHT PORTION OF THE ASSEMBLY.  THIS RESULTED IN EXTENDED AOG STATUS TO REPLACE THE ASSEMBLY A SECOND TIME.
