## Discrepancy

AT APPROX 0910(L), COMMENCED TAKEOFF ROLL. PIC/PF SET THRUST LEVERS TO APPROX 80 PERCENT AND COMMANDED SET POWER.  PM/SIC CALLED 80 KTS, PF CONFIRMED 80 KTS.  SHORTLY THEREAFTER, BOTH PILOTS SENSED YAW TO LT.  PIC/PF 
ATTRIBUTED YAW TO CROSSWIND COMBINED WITH DISCONNECTION OF NLG STEERING.  SIC/PM ATTRIBUTED YAW TO EFFORT TO
 AVOID APPROACHING BIRD.  WHEN INCREASED RUDDER-PEDAL INPUT DID NOT PRODUCE DESIRED CORRECTION BACK TO RW CENTERLINE, PF/PIC GLANCED AT 
ENGINE GAUGES NOTING LT ENGINE N1 DECREASING THROUGH 91% DOWN TO 86%.  PIC ABORTED TAKEOFF AT APPROX 100KTS.  
REDUCED BOTH THRUST LEVERS TO IDLE, APPLYING NORMAL BRAKING AND REVERSE THRUST.  PM NOTIFIED TOWER OF ABORT REPORTING ENGINE ROLL-BACK.
