Flight
While cruising, the commercial pilot observed the engine oil pressure gauge indicating near the maximum limit. The pilot did not recall the engine oil temperature reading. To address the high oil pressure, the pilot decided to conduct a precautionary landing on a snow-covered rural road.
Accident
The selected road was approximately 25 feet wide, straight, and free of obstacles. During the landing flare, the pilot reported that flat light conditions prevented him from seeing a plowed snow berm along the right edge of the road. When the airplane was about 5 feet above the ground, the right main landing gear ski collided with the snow berm. The impact caused the airplane to spin 180 degrees, after which it continued backwards into a large snow bank.
Damage
The accident resulted in structural damage to the right wing and fuselage of the airplane.
