While in cruise flight the engine began to lose power. The pilot elected to conduct a forced landing on a roadway due to rough and hilly terrain. The landing was successful; however, during the rollout the right wing impacted a sign, and rotated into a ditch. Subsequent to the accident an examination of the airplane engine revealed #3 cylinder was loose and six cylinder base studs were fractured. The engine had accumulated a total time of 1,100 hours time in service and 31 hours since the last inspection.
Probable Cause: other maintenance personnel's not correcting a loose cylinder assembly. Factors were loose engine cylinder assembly, fractured cylinder mounting hardware, the roadway, and road sign.
