Narrative:
Departing runway 30 at iad at approximately 90 KTS (prior to V1), the aircraft veered hard to the right. Directional control was lost and the aircraft struck a runway light. Although the wind was out of the left at 10 KTS gusting to 18 KTS, I do not believe this was the problem. The aircraft was extremely difficult to control and I believe the left engine surged, causing the instability since we were maintaining centerline prior to the occurrence. I feel nothing could have been done, except steering on the 31 checked more frequently. Supplemental information from acn 472987: departing off of runway 30 at dulles. I was the PNF. We brought the aircraft up to proper torque before releasing the brakes. Before reaching rotation speed the aircraft pulled drastically to the right side of the runway, striking a runway light. The captain was bringing the aircraft into reverse thrust to stop the aircraft while I was pushing on the yoke to give him more downward force on the control surfaces to help in steering. We then pulled off of the runway at taxiway Q4 to discuss what we thought was the problem and talking to ground, tower, company and passenger. After doing an engine runup, we decided that the best thing to do would be to deplane the passenger at the terminal, which we did. After postflt walkaround, we saw we had a propeller strike off a taxi light.

Title: JS31 LOST DIRECTIONAL CTL ON TKOF AND HIT A RWY LIGHT.
Narrative: DEPARTING RWY 30 AT IAD AT APPROX 90 KTS (PRIOR TO V1), THE ACFT VEERED HARD TO THE R. DIRECTIONAL CTL WAS LOST AND THE ACFT STRUCK A RWY LIGHT. ALTHOUGH THE WIND WAS OUT OF THE L AT 10 KTS GUSTING TO 18 KTS, I DO NOT BELIEVE THIS WAS THE PROB. THE ACFT WAS EXTREMELY DIFFICULT TO CTL AND I BELIEVE THE L ENG SURGED, CAUSING THE INSTABILITY SINCE WE WERE MAINTAINING CTRLINE PRIOR TO THE OCCURRENCE. I FEEL NOTHING COULD HAVE BEEN DONE, EXCEPT STEERING ON THE 31 CHKED MORE FREQUENTLY. SUPPLEMENTAL INFO FROM ACN 472987: DEPARTING OFF OF RWY 30 AT DULLES. I WAS THE PNF. WE BROUGHT THE ACFT UP TO PROPER TORQUE BEFORE RELEASING THE BRAKES. BEFORE REACHING ROTATION SPD THE ACFT PULLED DRASTICALLY TO THE R SIDE OF THE RWY, STRIKING A RWY LIGHT. THE CAPT WAS BRINGING THE ACFT INTO REVERSE THRUST TO STOP THE ACFT WHILE I WAS PUSHING ON THE YOKE TO GIVE HIM MORE DOWNWARD FORCE ON THE CTL SURFACES TO HELP IN STEERING. WE THEN PULLED OFF OF THE RWY AT TXWY Q4 TO DISCUSS WHAT WE THOUGHT WAS THE PROB AND TALKING TO GND, TWR, COMPANY AND PAX. AFTER DOING AN ENG RUNUP, WE DECIDED THAT THE BEST THING TO DO WOULD BE TO DEPLANE THE PAX AT THE TERMINAL, WHICH WE DID. AFTER POSTFLT WALKAROUND, WE SAW WE HAD A PROP STRIKE OFF A TAXI LIGHT.
