Analysis

Plt was advised by fss that Amarillo had snow flurries, visibility 4 miles and wind from 350 degs at 28 KTS gusting to 34 KTS, tucumcari, NM was reporting 2 miles visibility with light snow and areas further west were clearing. The plt departed Amarillo under a special VFR clearance and stated the wx was alright until west of Amarillo where visibility deteriorated to 1/2 mile with blowing snow. Because of the decreasing visibility and increasing winds the plt decided to land in an open field. Plt stated the engine intake screens iced up and a loss of RPM was experienced while maneuvering the helicopter into the wind for landing. The helicopter contacted the ground and rolled over to the right.
