Narrative:
Captain aborted initial takeoff due to aircraft drifting uncontrollably to the left. The following events were observed leading up to the abort: 1) flight control check during taxi out was normal. 2) winds were reported from the south at 20 KTS. 3) the takeoff thrust was set and stable prior to 60 KIAS. 4) forward pressure was being applied to the control column and approximately 50 percent right rudder was required to maintain centerline prior to the event. 5) at approximately 60 KIAS the aircraft drifted left of centerline and full right rudder was applied in an attempt to return to centerline. The rudder had no effect in steering the airplane to the right. 6) at approximately 70 KIAS the aircraft was halfway between the centerline and left runway edge and still drifting to the left despite full right rudder. 7) the captain elected to abort the takeoff. 8) the WX was clear but there was snow blowing across the runway. 9) the rejected takeoff and subsequent taxi to the gate were uneventful. 10) after coordination with maintenance and dispatch an aircraft swap was initiated and the flight was completed.
Original NASA ASRS Text
Title: B737-300 ABORTS TKOF WHEN UNABLE TO MAINTAIN RWY CENTERLINE WITH STRONG CROSSWINDS DESPITE USE OF FULL RUDDER AUTHORITY.
Narrative: CAPT ABORTED INITIAL TKOF DUE TO ACFT DRIFTING UNCONTROLLABLY TO THE L. THE FOLLOWING EVENTS WERE OBSERVED LEADING UP TO THE ABORT: 1) FLT CTL CHK DURING TAXI OUT WAS NORMAL. 2) WINDS WERE RPTED FROM THE S AT 20 KTS. 3) THE TKOF THRUST WAS SET AND STABLE PRIOR TO 60 KIAS. 4) FORWARD PRESSURE WAS BEING APPLIED TO THE CTL COLUMN AND APPROX 50 PERCENT R RUDDER WAS REQUIRED TO MAINTAIN CTRLINE PRIOR TO THE EVENT. 5) AT APPROX 60 KIAS THE ACFT DRIFTED L OF CTRLINE AND FULL R RUDDER WAS APPLIED IN AN ATTEMPT TO RETURN TO CTRLINE. THE RUDDER HAD NO EFFECT IN STEERING THE AIRPLANE TO THE R. 6) AT APPROX 70 KIAS THE ACFT WAS HALFWAY BTWN THE CTRLINE AND L RWY EDGE AND STILL DRIFTING TO THE L DESPITE FULL R RUDDER. 7) THE CAPT ELECTED TO ABORT THE TKOF. 8) THE WX WAS CLR BUT THERE WAS SNOW BLOWING ACROSS THE RWY. 9) THE REJECTED TKOF AND SUBSEQUENT TAXI TO THE GATE WERE UNEVENTFUL. 10) AFTER COORD WITH MAINT AND DISPATCH AN ACFT SWAP WAS INITIATED AND THE FLT WAS COMPLETED.
