Analysis

The acft hit the ground while trying to stay VFR under low ceilings at night. The student plt was returning from a x-country, for which he had no briefing on the weather, when the weather became worse. The student plt circumnavigated some of the thunderstorms but continued to fly lower. He said a downdraft forced him into the ground in a wheatfield. The acft cartwheeled and was destroyed. The plt crawled over a mile from the wreckage where he was found seriously injured 3 days later.
