## Discrepancy

DURING TAKEOFF ROLL FROM KPLN ON 11/18, THE FLIGHT CREW NOTICED A LIGHT HAZE ENTERING THE COCKPIT AND CABIN.  THE CREW ABORTED TAKE OFF AND SUBMITTED THE FOLLOWING AML - M230566: SMOKE IN CABIN AND COCKPIT ON TAKE OFF.  UPON INSPECTION AND TROUBLESHOOTING, TECHNICIANS FOUND THE DRAIN LINE FOR THE WATER SEPARATORS CRACKED AND LEAKING, ALLOWING LIGHT, OILY WATER TO MIX INTO THE ACM AIR.  COALESCER SOCKS WERE CLEANED, DRAIN LINE REPLACED, AND OPERATIONAL CHECKS FOUND NO SMOKE/HAZE ENTERING INTO THE AIRCRAFT.
