What happened
Following departure from the local airport, the pilot was operating the aircraft at an altitude of 10,600 feet MSL toward the leeward side of a ridge. The pilot reported that the aircraft maintained a good rate of climb until it reached the ridgeline, at which point the aircraft encountered downdrafts.
Upon reaching the ridge, the aircraft stopped climbing and began a descent. In an attempt to clear the ridge, the pilot raised the nose of the aircraft, which triggered the stall warning horn. The aircraft subsequently stalled and impacted terrain approximately 200 feet below the ridgeline.
