THE WITNESS REPORTED HEARING A VOICE ON THE RADIO SAY, 'BASE TO FINAL MT. MORRIS,' WHEN N6097G WAS EVEN WITH THE EAST END OF THE RUNWAY. THE WITNESS REPORTED THEN SEEING THE AIRPLANE MAKE A SHARP LEFT TURN AND STATED 'THE LEFT WING TIP 'STALLED' AND WENT DOWNWARD, PIVOTING ON THE LEFT WING TIP, TURNING AROUND 2-3 TIMES.' THEN, JUST PRIOR TO IMPACT WITH THE GROUND, THE PILOT APPEARED TO GAIN SOME CONTROL AS BOTH WINGS WERE LEVEL. POST ACCIDENT EXAMINATION REVEALED NO EVIDENCE OF PRE-IMPACT MECHANICAL MALFUNCTION WITH THE AIRFRAME, ENGINE, OR ACCESSORIES.
