Flight and Incident
The pilot was on a familiarization flight. After takeoff, a strong left turning tendency was noted. The pilot kept the engine power at a higher, time-limited setting, which caused the coolant temperature to exceed the maximum operating temperature of 180°F. No performance degradation was observed.
Decision and Landing Attempt
Concerned about possible engine power loss due to overheating, the pilot chose to make a precautionary landing. During the landing, the airplane bounced, prompting the pilot to initiate a go-around.
Collision and Damage
During the go-around, the airplane struck a hangar roof approximately 75 feet left of the runway centerline. The airplane then came to rest on the opposite side of the hangar. Substantial damage was sustained to both wings and the fuselage.
Mechanical Condition
The pilot reported no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
