## Analysis

AS THE CAPT APPLIED POWER & RELEASED BRAKES TO BEGIN THE TAKEOFF, THE ACFT STARTED TO DRIFT TO THE RIGHT. THE CAPT STATED THAT HE CLOSED THE THROTTLES & PUT THE #1 & #2 THROTTLES IN REVERSE. THE ACFT THEN BEGAN TO VEER LEFT &  SPUN AROUND NEARLY 1-1/2 TIMES. THE 1ST OFFICER STATED THAT AS THE ACFT INITIALLY DRIFTED TO THE RIGHT, HE NOTED THAT THE #4 ENG WAS NOT SPOOLING UP & HE SO INFORMED THE CAPT. THE RWY CENTERLINE HAD BEEN DEICED & WAS REPORTED WET WITH SCATTERED AREAS OF SNOW; BRAKING ACTION HAD BEEN REPORTED AS GOOD. THE CAPT SAID THAT LIGHT RAIN OR MIST WAS PRESENT AT THE TIME OF THE INCIDENT. THE UNDERSIDE OF THE #3 ENG COWLING WAS GASHED DURING THE INCIDENT & A LANDING LIGHT HAD TO BE REPLACED.
