Analysis

The stud plt was practicing stalls about 10 n of arpt. During recovery from a stall the eng began to run rough. The plt said he advanced throttle, applied carb heat, and tried to adjust mixture. The eng continued to run rough and lose pwr and the plt returned to the arpt. The acft was at about 200 ft upon arrival at the arpt and the plt attempted to align with rwy 16, which was the downwind rwy. Upon approaching rwy 16 the plt noted another acft landing in the opposite direction and turned to parallel the rwy. The acft continued to descend due to low pwr and stalled and crashed from about 20 ft AGL near midfield. Examination of the wreckage revealed that the mixture control was not in the full in position. Further examination of the wreckage and a test run of the eng did not reveal evidence of a pre-accident mechanical failure or deficiency.
