Aircraft involved

Probable cause & findings

The pilot’s failure to maintain clearance from terrain.

Factual narrative

The pilot reported that the purpose of the flight was to show his passengers the local area. They departed from the airport and proceeded north. Shortly after sunset, the pilot reversed course to return to the airport. During the return flight, he realized that he had turned into the incorrect canyon and was unable to out climb the rising terrain; subsequently, the pilot initiated a precautionary landing onto a hillside. During the landing, the right wing was substantially damaged. The pilot reported no mechanical failures or malfunctions that would have precluded normal operations.
