Analysis

The airplane sustained substantial damage when it stalled on takeoff and impacted terrain. The pilot reported observing approaching weather which he described as a squall line approximately two miles west of his location. He also noted that a light rain had started and was accompanied by pea-size hail. Weather conditions reported by the Pine Ridge Airport (IEN) automated surface observing system, at 1530, were winds from 340 degrees at 14 knots, gusting to 21 knots, 10 miles visibility, and few clouds at 3,300 feet above ground level. The weather report included a notation of thunderstorms in the vicinity and lightening in the distance to the west and southwest. The pilot recalled taking off to the south and had begun his initial climb. He reported that the aircraft started to buffet and he "knew a stall was coming." In his statement the pilot noted the "aircraft stalled on takeoff, not enough altitude for recovery." The aircraft bounced and the right wing and main landing gear impacted the terrain. The aircraft then nosed over.
