Background
During a post-accident telephone conversation with a National Transportation Safety Board investigator-in-charge, the pilot reported that prior to the accident flight, she placed tape on the intake side of the oil cooler. Her intention was to prevent the oil "from running so cool."
Accident Sequence
Approximately 15 minutes after takeoff, the pilot observed that the oil temperature was "over the red line." She decided to make a precautionary off-airport landing. During the landing roll, the pilot applied the brakes excessively, causing the airplane to nose-over.
Outcome
The accident resulted in substantial damage to the aircraft. A witness, another pilot, observed the accident, landed without incident, and provided assistance to the accident pilot.
The probable cause of the accident was not stated in the source.
