Nobody was injured.

The pilot's failure to maintain directional control during a precautionary landing. A factor was the pilot's unapproved maintenance modification resulting in the loss of oil pressure and partial loss of engine power.

Read the full NTSB narrative

During the takeoff and initial climb, the engine power was 100 rpm lower than expected, and the oil pressure decreased to 0. The pilot initiated a left turn for a precautionary landing at the airport. The engine continued to lose power during the approach, but it did not experience a total loss of power. The airplane was not aligned with the centerline as it touched down on a runway, and traveled off the left side. Examination of the airplane revealed that the pilot had recently installed a homemade oil cooler adapter on the certificated engine.
