Narrative:

Upon landing on runway 10 at iyk, the captain pulled the RPM levers to low and the aircraft started to drift right. I made sure the right RPM lever was low to engage the nose wheel steering (NWS). The captain pushed the steering button on the left power lever to override any steering malfunction. He also pushed the park button to gain more steering authority. Still, with full left rudder, left brake, full left reverse, and positive right thrust, the aircraft continued to drift right. We left the runway about 7 KTS, 1700 ft from the rollout end. The aircraft came to a stop about 30 ft off the pavement. The NWS then responded normally to inputs so we taxied back onto the pavement and to the gate. None of the 8 passenger were injured. The aircraft sustained 1 bent propeller tip from a large bush. This was the second leg after a 13 hour overnight so both crew were very fresh and alert. The aircraft had been written up 2 days previous for a similar problem by another crew. According to the maintenance log the problem had been corrected. I feel that everything that could be done was done. I do not know if the actions taken were correct but I feel that they were.

Title: RWY EXCURSION BY LTT DURING LNDG PROC ROLLOUT.

Narrative: UPON LNDG ON RWY 10 AT IYK, THE CAPT PULLED THE RPM LEVERS TO LOW AND THE ACFT STARTED TO DRIFT R. I MADE SURE THE R RPM LEVER WAS LOW TO ENGAGE THE NOSE WHEEL STEERING (NWS). THE CAPT PUSHED THE STEERING BUTTON ON THE L PWR LEVER TO OVERRIDE ANY STEERING MALFUNCTION. HE ALSO PUSHED THE PARK BUTTON TO GAIN MORE STEERING AUTHORITY. STILL, WITH FULL L RUDDER, L BRAKE, FULL L REVERSE, AND POSITIVE R THRUST, THE ACFT CONTINUED TO DRIFT R. WE LEFT THE RWY ABOUT 7 KTS, 1700 FT FROM THE ROLLOUT END. THE ACFT CAME TO A STOP ABOUT 30 FT OFF THE PAVEMENT. THE NWS THEN RESPONDED NORMALLY TO INPUTS SO WE TAXIED BACK ONTO THE PAVEMENT AND TO THE GATE. NONE OF THE 8 PAX WERE INJURED. THE ACFT SUSTAINED 1 BENT PROP TIP FROM A LARGE BUSH. THIS WAS THE SECOND LEG AFTER A 13 HR OVERNIGHT SO BOTH CREW WERE VERY FRESH AND ALERT. THE ACFT HAD BEEN WRITTEN UP 2 DAYS PREVIOUS FOR A SIMILAR PROBLEM BY ANOTHER CREW. ACCORDING TO THE MAINT LOG THE PROBLEM HAD BEEN CORRECTED. I FEEL THAT EVERYTHING THAT COULD BE DONE WAS DONE. I DO NOT KNOW IF THE ACTIONS TAKEN WERE CORRECT BUT I FEEL THAT THEY WERE.
