## Discrepancy

SEA - BURNING SMELL AND LOUD SQUEAL COMING FROM COCKPIT PACK.  STOPPED WHEN COCKPIT PACK WAS TURNED OFF.  MAINTENANCE INSPECTED AND PLACED ON MEL.  LATER THAT DAY AT GEG MAINTENANCE FOUND THE INLET DUCT TO WATER SEPARATOR COLLAPSED.  THE WATER SOCK WAS INSPECTED AND LOOKED GOOD, MAINTENANCE THEN INSTALLED WATER SEPARATOR AND DUCT, PERFORMED A GROUND RUN, OPERATIONAL CHECKS WERE NORMAL.  CLEARED THE MEL.  AIRCRAFT WAS RETURNED TO SERVICE.
