Analysis

The acft was destroyed during a precautionary landing after the left side of the eng cowling opened shortly after takeoff. The plt reported the cowling opened at an alt of aprx 50 ft AGL. A climb to 300 ft was made and the acft was turned onto downwind. The plt stated in an interview that because of turbulence and a fear the cowling would separate from the acft, he panicked and tried to put the acft down in an open fld. The acft contacted the terrain in a nose down left bank attitude.
