Analysis

The acft was a george killian/briegleb BG-12B, experimental, home built glider. An owner reported that the plt had come from new Mexico to buy the glider. After spending about 3 hrs in familiarization training, the plt went on his 1st flt which was uneventful. He then went on a 2nd flt which was approximately 1 hr in duration. As the glider was on final apch to land & was at about 100 to 150 ft AGL, it entered a nose down attitude & crashed. According to witnesses, the glider smoothly pitched over into a nose down attitude without stalling. An exam of the flt controls was made, but no preimpact malfunction or failure of the elevator control sys was found. A pathological exam of the plt revealed no medical problems that would have resulted in the accident.
