Analysis
The acft did a hard landing during autorotation after the engine ran rough and quit at 250 ft AGL during takeoff. The pilot had leaned the mixture, he said, prior to takeoff and he was not sure if he pushed the mixture to full rich when the engine started to miss and run rough. During autorotation he maintained 50 mph with little flare for landing. The engine was checked after the accident and operated normally. The mixture was slowly turned to see how it would be when the engine ran rough. It was about 3 inches from full rich.
