A C-23 drifted off the runway after landing; possibly due to crosswinds and/or nosewheel steering issues. No damage resulted.

Narrative

After a routine landing; the aircraft began to drift from left to right of the runway centerline. All attempts to stop the right/left drifting were not successful and the aircraft departed the runway to the left after a ground roll of about 1500 FT. The aircraft continued through the short level grass area and reemerged on an intersecting runway without incident and with the control tower advising that there was no problem and the aircraft was cleared to our usual parking spot. Contributing factors could have been gusty and variable winds at 30-60 degrees each side of the runway centerline at 7-15 KTS. There is also a possibility of the aircraft having nosewheel steering problems that are now being reviewed by our mechanic. There is a bungee system in the nosewheel steering of this type aircraft that tends to have a vague feel to it and is subject to minute over correction issues in certain gust conditions. There is also an interconnect between the nosewheel steering and the rudder-aileron system. This is being reviewed. There were no other aircraft involved; and no conflict of any type was noted. No other aircraft movements were in evidence either on the ground or in the traffic pattern. There was no damage to the aircraft; nor any personal injury to the solo pilot or any damage to structures.
