According to the 549-hour pilot, the engine lost power without warning while flying at 10,500 feet, about 20 minutes after takeoff. The pilot elected to execute a forced landing on a dirt road. His initial rollout was successful, but approximately 120 feet from the touch down point, the right wing struck a yucca cactus plant. It continued down the dirt road and the left wing stuck a cactus plant, and the left main landing gear collapsed. An external examination of the engine, revealed a bulge and crack in the upper engine case near the #1 cylinder. The reason for the internal engine failure was not determined.
