Analysis

During ILS rwy 9 appraoch acft disappeared from radar at one mile short of rwy. Acft impacted in level attitude with landing gear extended on a northerly heading one half mile short and about one quarter mile left of rwy centerline. Plt and CFI both stated the acft was turned right to fly centerline. Plt became spatially disoriented during approach and allowed acft to turn nearly 90 degrees off course and descend below decision height.
