(CUSTER TOWNSHIP) -- A 60-year old Sandusky man escaped injury after making an emergency landing with his aircraft in a farmer's field. Sheriff Garry Biniecki says Vernon Hazzard called 9-1-1 shortly before 9:30 a.m. Saturday after landing the Cherokee PA 32 260 airplane in Richard Gerstenberger's field north of Sandusky at Custer and Stoutenburg Roads. Hazzard informed authorities that he was making practice takeoffs and landings before heading out to Alpena. As he was in the air he started losing speed, causing engine difficulties. The aircraft touched the top of a tree causing minor damage to the wings of the plane. Hazzard was able to successfully land the aircraft without injury or additional damage to his plane. Sheriff's deputies were assisted by the Sandusky Police Department, Sandusky City Airport Manager Joe Allen, and Sanilac County Emergency Management Director Todd Hillman. An investigation into what caused the aircraft's engine difficulties continues.
