Analysis

According to the plt, when he arrived in the area of the arpt, he contacted the flt svc station (fss) & was advised that rwy 30 (a 9002' asphalt rwy) was active & that the wind was from 210 deg at 10, gusting 15 KTS. The arpt also had a turf rwy (rwy 3/21) which was 3400' long. The plt stated that drg touched down on rwy 30, a gust of wind lifted the left wing & the acft veered off the right side of the rwy. He applied power, but the right wing hit the ground & the acft cartwheeled. Shortly after coming to rest, it began burning & was destroyed by fire.
