Sept. 14 (UPI) -- The helicopter crash that killed country music star Troy Gentry of Montgomery Gentry, was caused by engine failure according to a report released by the National Transportation Safety Board.
"Several minutes after takeoff, the pilot reported over the airport UNICOM frequency that he was unable to control engine rpm with throttle inputs. He reported he could 'roll' the twistgrip, but that there was no corresponding change in engine rpm when he did so," the report obtained by E! News said.
