The pilot reported that shortly after takeoff, the engine overheated, then lost coolant. The coolant covered the windshield and he had a hard time seeing in front of him for the return to the airport for landing. During the touchdown, the aircraft landed hard and slid off the side of the runway. During an inspection by maintenance personnel, it was found that the left wing spar was bent and required replacement. It was also found that the relief valve to the aftercooling system header tank failed, subsequently releasing the coolant. The aftercooling system is of the low pressure type, incorporating a relief valve which relieves at approximately 18 to 20 pounds per square inch. The flight manual states in several areas for start, ground operations and takeoff to closely monitor coolant temperatures to prevent overheating.
Probable Cause: The malfunction of the cooling system pressure relief valve and the pilot's failure to follow procedures. An engine over temperature, a coolant leak as a result of a relief valve failure, an obstructed windshield which was covered with coolant fluid, and an improper flare resulting in a hard landing were factors.
