In a written statement the pilot reported that the purpose of the flight was to practice aerobatics in the local area. He reported that shortly after rolling the airplane inverted, to accomplish a "belt check", oil appeared on the airplane's windscreen and canopy. The oil on the windscreen impaired the pilot's vision and he elected to return to the departure airport and land. He stated that the airplane touched down on the left edge of the runway, encountered rough/uneven terrain and the nose gear collapsed. The pilot stated that he had not tightened the engine oil cap prior to departure. The oil cap was later found laying on the ground in the run-up area of the airstrip.
Probable Cause: The pilot's failure to properly align with the runway. Factors include rough/uneven terrain, inadequate preflight planning and diminished forward visibility.
