N56417
PIPER PA-28-180
While in cruise flight the pilot noted a decrease in engine rpm. He began to troubleshoot the problem and reversed course to head toward more favorable terrain for a forced landing. After completing the turn, the engine seized, and the pilot performed a forced landing to a pasture. During the landing roll, the right wing impacted a bale of hay, resulting in substantial damage. An examination of the engine revealed that the loss of engine power and resultant seizure was due to a loss of engine oil. Further examination revealed that the bolts on the vacuum pump were loose and the engine oil was exiting at that location. An examination of the airframe and remaining systems revealed no anomalies.
