The NTSB's narrative final · quoted from the NTSB record

The private pilot reported that, after a preflight inspection and engine run-up revealed no anomalies, he and a passenger departed, circled a nearby mountain, then descended to an altitude about 750 ft above ground level. Shortly thereafter, the engine experienced a partial loss of power. The pilot attempted to restore engine power, but was unsuccessful, and he elected to land the airplane on a dry wash. As the airplane touched down, the right main landing gear sank into the dirt, and the airplane made a sharp turn to the right. The airplane impacted a tree and came to rest nose down. The atmospheric conditions at the time of the accident were not conducive to the formation of carburetor icing. A postaccident engine examination and test run revealed no anomalies that would have precluded normal operation; therefore, the reason for the loss of partial engine power could not be determined.
