An MD 500 helicopter crashed west of Township Road 188 in Liberty Township of Bellefontaine, Logan County, Ohio, at about 4:45 p.m. on July 29.
Leo Boucher, 50, pilot of the crashed helicopter suffered life threatening injuries and is being treated at Grant Medical Center in Columbus. Boucher works for South Carolina-based Rotor Blade.
The Ohio Highway Patrol post at Marysville rules out use of any alcohol or drugs by the pilot.
The helicopter was equipped with an aerial saw and was deployed for tree-trimming and brush-clearing for a bike path. Apparently the pilot lost control of the helicopter and crashed into the tree line.
The crash remains under investigation by the FAA.
