The Piper PA18-150 pilot reported that he and his father had flown to a location near Willcox, Arizona, to camp and hunt. They made three passes over an open area to find a suitable landing spot.
The pilot stated that the grass appeared to be knee-to-hip height, but he believed it was safe to land.
He set up for landing, and on the landing rollout, about 20-30 knots, the left main landing gear wheel hit an unseen, large embedded boulder that collapsed the left main landing gear. The wing sustained substantial damage.
The NTSB determined the probable cause as the pilot’s decision to land off airport on unsuitable terrain that resulted in a collision with hidden objects.
