## Discrepancy

(CAN) THE PILOT WAS DESCENDING WHEN ALL OF A SUDDEN THE CABIN AREA FILLED UP WITH A MIST ORIGINATING FROM THE THE DEFROST VENTS. THE MIST WAS SO STRONG THAT THE PILOT HELD HIS BREATH AND OPENED THE FUSELAGE DOOR SO THE MIST COULD EXIT THE AC.  AFTER A FEW SECONDS THE MIST DISSIPATED SO THE PILOT COULD BREATH NORMALLY. THE PILOT LANDED AT STAGING SITE AND THE AC WAS GROUNDED. THE ENGINEER WAS CALLED TO TROUBLESHOOT THE PROBLEM.  WE BELIEVE IT IS THE FUEL CONTROL THAT CAUSED THIS FUEL MIST IN THE CABIN. THE FUEL CONTROL HAS ABOUT 1400 HOURS SINCE LAST OVERHAUL THE TECH. (3000 HOUR O/H BY MFG) (TC NR 20071203007)
