## Analysis

THE ENG FAILED ENROUTE & WHILE LANDING ON A LOGGING ROAD THE RIGHT WING CONTACTED VEGETATION CAUSING THE ACFT TO SWERVE & COME TO REST NOSE LOW. THE ENG HAD BEEN INSPECTED 1 HR PREVIOUS TO THE ACCIDENT & HAD 8 HRS OF OPERATING TIME SINCE NEW AT THE INSPECTION. EXAMINATION OF THE OIL TUBE WHICH DELIVERS OIL TO THE OIL COOLER REVEALED A SEPARATION NEAR ONE OF THE BEVELED ENDS WITH LONGITUDINAL STRIATIONS, OR "TOOL MARKS", AT BOTH ENDS. EXAMINATION OF THE FRACTURE SURFACE DISCLOSED FEATURES INDICATIVE OF FATIGUE EMANATING FROM NUMEROUS SITES IN THE VICINITY OF THE TOOL MARKS. #1 & 3 CONNECTING RODS DISCLOSED BLACK DISCOLORATION TYPICAL OF EXCESSIVE HEATING. #3 CONROD CAP WAS FRACTURED. THERE WAS EVIDENCE OF EXTREME WEAR ON THE #1 BEARING, & MODERATE TO HEAVY WEAR ON THE #3 BEARING.
