Analysis

The Piper PA-18-150 encountered turbulent wind conditions and dragged the left wing during a takeoff ground run from rwy 33. The plt reported that during the takeoff ground run, the right wing lifted causing the left wing to drag on the rwy. The aircraft then swerved to the left and departed the rwy. The fss (located on the arpt) reported that at the time of the accident, the winds were from 260 deg at 7 KTS. Several 'dust devils' were observed in the area during the day, but none were observed on the arpt. The plt also indicated that he received a weather briefing and was aware of the reported weather phenomena.
