Incident Overview
During a low-level pipeline patrol flight, the pilot observed the engine oil pressure indication drop to zero. The pilot attempted to increase engine power and initiate a climb, but the engine began to run rough. Subsequently, the pilot performed a landing on the pipeline right-of-way. During the landing, the airplane collided with rough terrain and nosed over.
Post-Crash Examination
A post-crash examination of the engine revealed no evidence of any preexisting mechanical malfunction or failure. Subsequent engine test-runs were conducted, which showed normal oil pressure indications on both the cockpit gauge and an external, direct-reading gauge.
