The acft was lndd & sank in a river, short of an open fld. When the acft was recovered from the water, the mixture control was found about 1-1/8 inch from the full rich position. No preimpact part failure or malfunction was found. The eng was dried out & serviced with new oil. An eng run was made, but the power was limited to about 1500 RPM to avoid vibration due to a bent prop. The plt said that at the time of takeoff, he had leaned the mixture due to the ambient temp. The 1452 temp at Knoxville was 88 deg.
