Narrative:

Preflight at el paso, first officer notified main struts were extended more than usual. Taxi and departure out of el paso was uneventful. During rollout at mci after landing, I exited off a high speed taxiway. When I engaged the steering button to continue the turn on the taxiway, the nosewheel did not respond and I was unable to taxi over the hold short line. We immediately informed the tower of our situation. Tower instructed an aircraft to go around and another to abort takeoff. We were told to contact ground. Our steering returned after a few moments, and we were able to taxi back to the FBO without any more difficulties. Postflt inspection showed the struts were extended even more than at departure due to our lighter weight. Maintenance inspected the struts and determined the struts were over svced causing them to interfere with the squat switch, thus not allowing the steering to operate momentarily.

Title: LEARJET 25 CAPT HAD NOSEWHEEL STEERING FAILURE WHEN ATTEMPTING TURNOFF FROM RWY.

Narrative: PREFLT AT EL PASO, FO NOTIFIED MAIN STRUTS WERE EXTENDED MORE THAN USUAL. TAXI AND DEP OUT OF EL PASO WAS UNEVENTFUL. DURING ROLLOUT AT MCI AFTER LNDG, I EXITED OFF A HIGH SPD TXWY. WHEN I ENGAGED THE STEERING BUTTON TO CONTINUE THE TURN ON THE TXWY, THE NOSEWHEEL DID NOT RESPOND AND I WAS UNABLE TO TAXI OVER THE HOLD SHORT LINE. WE IMMEDIATELY INFORMED THE TWR OF OUR SIT. TWR INSTRUCTED AN ACFT TO GAR AND ANOTHER TO ABORT TKOF. WE WERE TOLD TO CONTACT GND. OUR STEERING RETURNED AFTER A FEW MOMENTS, AND WE WERE ABLE TO TAXI BACK TO THE FBO WITHOUT ANY MORE DIFFICULTIES. POSTFLT INSPECTION SHOWED THE STRUTS WERE EXTENDED EVEN MORE THAN AT DEP DUE TO OUR LIGHTER WT. MAINT INSPECTED THE STRUTS AND DETERMINED THE STRUTS WERE OVER SVCED CAUSING THEM TO INTERFERE WITH THE SQUAT SWITCH, THUS NOT ALLOWING THE STEERING TO OPERATE MOMENTARILY.
