On June 2, 1994, approximately 1530 mountain daylight time (MDT), an Ayres S2R, N8542, impacted trees during a forced landing seven miles east of Burley, Idaho. The commercial pilot, who was the sole occupant of the airplane, received no injuries, but the aircraft sustained substantial damage. The agricultural application flight, which departed a county road approximately 1430 MDT, was in visual meteorological conditions at the time of the accident. No flight plan had been filed, and there was no report of an ELT activation. The pilot said that the engine lost power as he started a pull-up from an application run. He executed a forced landing in an adjacent field, and impacted a line of trees during the landing roll. It was later discovered that the carburetor mounting bolts were loose, and the carburetor was not firmly seated against its mounting flange.
