Analysis

A cattle rancher was flying his aircraft looking for stray cattle and checking the condition of the ranch. He was at approximately 300 feet AGL when he spotted cattle that had strayed off the ranch. The pilot turned to get a better view of the cattle and flew into a box canyon. The investigation revealed the aircraft impacted the ground in a near verticalattitude at the FAR end of the box canyon. No preimpact malfunctions/failures were found.
