Read the full NTSB narrative
On departure, the left engine of the twin-engine airplane failed. Postincident examination of the left engine revealed a six-inch hole in the case, and that two connecting rod bolts on the number one cylinder had separated. Examination indicated that one of the rod bolt failed due to fatigue. An SEM examination of the outside surface adjacent to the fracture face revealed no indication of a manufacturing anomaly. Fretting damage was found on the arm of the connecting rod that was associated with this bolt. The physical evidence suggested that the bolt was improperly torqued. Maintenance records indicate that the left engine received a major overhaul 2.5 hours before the incident. A representative of the engine manufacturer said that the rod bolts on this engine are properly installed when the tightening of the nut stretches the bolt to a specified dimension.
