Investigating agency: NTSB
Narrative:
The engine of the amateur built, experimental aircraft seized and stopped after the seam of the automotive-type oil cooler opened up in-flight, resulting in loss of the engine oil supply and oil starvation of the engine. The pilot attempted to make a forced landing in a field, however, the right main landing gear entered a hole and the aircraft cartwheeled.
Probable Cause: A crack which developed in the automotive-type oil cooler of the experimental, amateur built aircraft and permitted the engine oil supply to flow overboard.
