At 15:35 Pacific time, a Cessna 177RG struck mountainous terrain during approach to Pauma Valley Airport. The pilot and passenger suffered minor injuries. The pilot said he was descending VFR and was on an extended downwind when he intentionally flew into what appeared to be an isolated cloud. The cloud was larger than he anticipated and eventually he saw vegetation on a mountainside a short distance in front of them. The airplane crashed on upsloping terrain.
