The certified flight instructor (CFI) and the pilot under instruction (PUI) were going on a series of cross-country flights to allow the PUI to build flight time. Motorists observed the wreckage near a road that was in the flat bottom of a canyon whose floor width varied from an estimated 50 yards at the narrowest point to 200 yards at the widest point. The canyon made several left and right turns as it wound its way uphill in a general southeasterly direction. The canyon sides appeared to be several hundred feet higher than the accident site elevation and the rim appeared to be about 100 feet higher at the head of the canyon. An evaluation of the ground scars and impact signatures on the wreckage disclosed that the airplane was in a left turn attempting to reverse course out of the box canyon when the left wing tip dug into the ground. The airplane then tumbled so that it was pointing down canyon when it came to rest. No evidence of a mechanical failure or malfunction was noted during the post accident inspection.
Probable Cause: The inadequate in-flight/planning decision of both pilots to fly up a box canyon at low altitude, and their failure to maintain clearance from the terrain.
