Incident Details
During cruise flight, oil began to cover the windshield, obstructing the pilot's view. In response, the pilot performed a precautionary landing in a field. During the landing roll, the pilot observed a fence ahead and applied power to clear it. Due to having no useful vision in the left eye, the pilot banked the airplane to the right to locate a suitable landing location. During the turn, the right wing collided with a tree.
Engine Examination
Examination of the engine after the incident revealed that the crankshaft oil seal was partially extruded. This condition allowed oil to exit the engine. At the time, the engine had accumulated 176.5 hours since its last overhaul.
