Narrative:

The aircraft departed teb for apa, no WX factors at departure airport. Thin cloud layers existed during climb out. The flight proceeded normally until touchdown on runway 17L at apa. The approach and landing were normal until momentarily after the nose gear made contact. At that time the aircraft began pulling to the right. Normal aileron and rudder control inputs had no effect and the aircraft continued to move towards the edge of the runway. Both pilots attempted to use left brake to arrest the turn to no effect. Prior to leaving the runway an attempt was made to utilize the nosewheel steering tiller but it was jammed and would not twist to the left. After the aircraft departed the runway through some hard packed snow and onto the rough ground the tiller became free. Due to the efforts of both pilots utilizing the brakes, steering, and engine shutdown, the aircraft was brought to a safe stop intact on the airport infield with no injuries to passenger or crew. Centennial tower was advised of our position and condition, and assistance was requested. The aircraft shutdown checklist was completed and passenger and crew evacuate/evacuationed the aircraft. Only light winds existed at apa, with no WX factors. Maintenance is still examining the aircraft for damage and possible cause of the steering system failure.

Title: AN ATX FLC RPTS THAT THEY HAD A STEERING FAILURE DURING THE ROLLOUT IN AN HS25. NO INJURIES.

Narrative: THE ACFT DEPARTED TEB FOR APA, NO WX FACTORS AT DEP ARPT. THIN CLOUD LAYERS EXISTED DURING CLBOUT. THE FLT PROCEEDED NORMALLY UNTIL TOUCHDOWN ON RWY 17L AT APA. THE APCH AND LNDG WERE NORMAL UNTIL MOMENTARILY AFTER THE NOSE GEAR MADE CONTACT. AT THAT TIME THE ACFT BEGAN PULLING TO THE R. NORMAL AILERON AND RUDDER CTL INPUTS HAD NO EFFECT AND THE ACFT CONTINUED TO MOVE TOWARDS THE EDGE OF THE RWY. BOTH PLTS ATTEMPTED TO USE L BRAKE TO ARREST THE TURN TO NO EFFECT. PRIOR TO LEAVING THE RWY AN ATTEMPT WAS MADE TO UTILIZE THE NOSEWHEEL STEERING TILLER BUT IT WAS JAMMED AND WOULD NOT TWIST TO THE L. AFTER THE ACFT DEPARTED THE RWY THROUGH SOME HARD PACKED SNOW AND ONTO THE ROUGH GND THE TILLER BECAME FREE. DUE TO THE EFFORTS OF BOTH PLTS UTILIZING THE BRAKES, STEERING, AND ENG SHUTDOWN, THE ACFT WAS BROUGHT TO A SAFE STOP INTACT ON THE ARPT INFIELD WITH NO INJURIES TO PAX OR CREW. CENTENNIAL TWR WAS ADVISED OF OUR POS AND CONDITION, AND ASSISTANCE WAS REQUESTED. THE ACFT SHUTDOWN CHKLIST WAS COMPLETED AND PAX AND CREW EVACED THE ACFT. ONLY LIGHT WINDS EXISTED AT APA, WITH NO WX FACTORS. MAINT IS STILL EXAMINING THE ACFT FOR DAMAGE AND POSSIBLE CAUSE OF THE STEERING SYS FAILURE.
