THE PLT DEPARTED PORT COLUMBUS UNEVENTFULLY, FLEW FOR APRX 40 MINS THEN SHOT A VOR APCH TO THE MDA AT PORTAGE COUNTY. THIS FLD DOES NOT HAVE A WX REPORTING FACILITY. THE PLT THEN PERFORMED A MISSED APCH UPON REACHING MDA. DURING THE MISSED APCH AND AFTER ACKNOWLEDGING TWO ATC RADIO CALLS, HE DROPPED OFF RADAR AT APRX 600 FT AGL. THE ACFT CRASHED ONE MILE FROM THE FLD, LEFT OF THE NORMAL MISSED APCH GROUND TRACK. A WITNESS HEARD THE ENG RUNNING JUST PRIOR TO IMPACT. AN EXAM OF THE WRECKAGE REVEALED NOTHING THAT WOULD CAUSE DIFFICULTY EXCEPT AN ELEVATOR JACK-SCREW SETTING THAT WOULD EQUATE TO NOSE DOWN TRIM FORCE. DAMAGE TO VIRTUALLY ALL ACFT COMPONENTS WAS EXTENSIVE. THE PLT EARNED HIS IFR RATING 3 MONTHS PRIOR TO THE ACCIDENT, BUT CLAIMED 33.6 HRS OF ACTUAL IFR FLYING SINCE HIS IFR CHECKOUT. HE HAS 4.3 HRS LOGGED IN THE CESSNA 210. THE RADAR EQUIPPED, TURBOCHARGED 310 HP CESSNA 210 WAS THE MOST COMPLICATED ACFT THE PLT WAS QUALIFIED TO FLY.
