Narrative:

After landing in aspen; co; I turned off the runway. Almost immediately we experienced violent nosewheel shimmy at approximately 5 KTS. I stopped the aircraft. The captain went outside to examine the nosewheel and found the steering mechanism disconnected and the pin removed. The pin had the safety wire still installed. He reconnected the steering and installed the pin and we were towed to parking. A maintenance inspection determined there was no damage and the aircraft was cleared for flight.
