Burkhart Grob G 103 TWIN II N4446Y accident near Levan, Utah

Probable cause

The glider’s encounter with atmospheric conditions where the lift was not sufficient to maintain flight which resulted in an off-airport landing and a collision with a fence.

NTSB analysis

The pilot reported that during the flight, the glider encountered insufficient lift to maintain flight and he decided to land off airport. He performed a high recon of the area and selected a landing site on the north side of a local reservoir, along the shoreline. While on downwind for the intended landing area, he did not see any obstacles, and performed a teardrop turn to final. The glider touched down in the approximate area he intended to, however, during landing roll, the glider collided with a barbed wire fence and sustained substantial damage to the right wing and the rear canopy. The pilot reported that there were no preaccident mechanical failures or malfunctions with the glider that would have precluded normal operation.
