Given the airplane's low altitude, he chose to make an emergency landing in a nearby field, during which the airplane impacted a ditch, nosed over, and came to rest inverted. The airplane erupted into flames and was consumed by fire. The postcrash fire damage precluded examination of the airplane, and the reason for the loss of engine power was not determined based on the available information. ## Factual narrative On July 12, 2018, about 1645 mountain daylight time, a Cessna 150L airplane, N6908G, was destroyed when it was involved in an accident near Ontario, Oregon.
