An MO20 pilot experienced a loss of control during landing and after the aircraft left the runway, the pilot performed a go around. Through coordination with the tower, the reporter determined that the nosewheel was not centered. The reporter landed a second time using a soft field landing technique. Maintenance inspection revealed that the nosewheel steering bolt was partially out of place.

Narrative:
On landing at geu nosewheel was canted left and not attached, making it veer off runway. I pwred up and went around. Tower confirmed after fly-by that wheel was angled off. After landing uneventfully the second time, a mechanic found nosewheel steering bolt partially out of place. No control of nosewheel. This aircraft had new tires put on 2 lndgs prior and was towed for this work. I believe this dislodged the bolt or aggravated the bolt out of position. Callback conversation with reporter revealed the following information: the aircraft is an MO20 (C model). The owner feels certain that maintenance overextended the turning limitations of the nosewheel. Since the bolt is well up underneath the cowling, the pilot states that he could not have detected this situation on preflight. His first indication of anything being wrong was during landing. When the aircraft shot off toward the side of the runway, the reporter rotated the nose while adding power, and went around. On the second attempt to land, the nosewheel was still not centered, but the reporter held the nose off until the aircraft was literally stopped.

Title: AN MO20 PLT EXPERIENCED A LOSS OF CTL DURING LNDG AND AFTER THE ACFT LEFT THE RWY, THE PLT PERFORMED A GAR. THROUGH COORD WITH THE TWR, THE RPTR DETERMINED THAT THE NOSEWHEEL WAS NOT CTRED. THE RPTR LANDED A SECOND TIME USING A SOFT FIELD LNDG TECHNIQUE. MAINT INSPECTION REVEALED THAT THE NOSEWHEEL STEERING BOLT WAS PARTIALLY OUT OF PLACE.
Narrative: ON LNDG AT GEU NOSEWHEEL WAS CANTED L AND NOT ATTACHED, MAKING IT VEER OFF RWY. I PWRED UP AND WENT AROUND. TWR CONFIRMED AFTER FLY-BY THAT WHEEL WAS ANGLED OFF. AFTER LNDG UNEVENTFULLY THE SECOND TIME, A MECH FOUND NOSEWHEEL STEERING BOLT PARTIALLY OUT OF PLACE. NO CTL OF NOSEWHEEL. THIS ACFT HAD NEW TIRES PUT ON 2 LNDGS PRIOR AND WAS TOWED FOR THIS WORK. I BELIEVE THIS DISLODGED THE BOLT OR AGGRAVATED THE BOLT OUT OF POS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE ACFT IS AN MO20 (C MODEL). THE OWNER FEELS CERTAIN THAT MAINT OVEREXTENDED THE TURNING LIMITATIONS OF THE NOSEWHEEL. SINCE THE BOLT IS WELL UP UNDERNEATH THE COWLING, THE PLT STATES THAT HE COULD NOT HAVE DETECTED THIS SIT ON PREFLT. HIS FIRST INDICATION OF ANYTHING BEING WRONG WAS DURING LNDG. WHEN THE ACFT SHOT OFF TOWARD THE SIDE OF THE RWY, THE RPTR ROTATED THE NOSE WHILE ADDING PWR, AND WENT AROUND. ON THE SECOND ATTEMPT TO LAND, THE NOSEWHEEL WAS STILL NOT CTRED, BUT THE RPTR HELD THE NOSE OFF UNTIL THE ACFT WAS LITERALLY STOPPED.
