NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

Several hikers saw the airplane fly past them at low altitude and into a gorge. They videotaped the pilot waving at them. They said the airplane disappeared below the lip of the gorge, and then they heard the sound of impact. Several hikers climbed down the canyon wall and proceeded to the wreckage while others notified authorities. The accident site was approximately 300 feet above the canyon floor. Examination of the airplane revealed it was either turning or spinning at the moment of impact. Flight control continuity was established and no systems anomalies were noted. Another pilot said he noticed mountain wave-type winds in that area of the canyon, making turbulence likely. The accident pilot had flown in the canyon before, and was known to fly at low airspeeds and altitudes. The pilot had been warned by other pilots that it was not safe to fly in the canyon in a light aircraft.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's intentional low altitude flight in a confined area and an inadvertent stall/spin. Contributing factors in this accident were the blind/box canyon and the aircraft's low airspeed.
