Analysis

During cruise flight, the engine lost all power due to a connecting rod failure and the flight instructor attempted to land the aircraft on a road. Due to a vehicle on the road, the flight instructor steered the aircraft into a field during landing roll and the aircraft struck some rocks causing damage to the main landing gear mounting structure. The reason for the connecting rod failure could not be determined due to secondary damage.
