Continental; IO520; Main Bearing Failure; ATA 8520

The mechanic describes one of this engine’s main bearings as “...spun...”, whose rotation cut off the oil supply to the number two cylinder connecting rod. Friction and inertia provide the energy to send the connecting rod through the engine case. No speculation for the spun bearing was provided, but time since overhaul was given as 1,676 hours.

Part Total Time: 3,364 hours.
