On June 12, 1993, at 0945 Pacific daylight time, a Cessna 150L, N19507, collided with rising terrain near Yucaipa, California, during climb out from a practice forced landing. Visual meteorological conditions prevailed at the time and no flight plan was filed for the operation. The aircraft incurred substantial damage. The certificated flight instructor and his non certificated dual primary student were not injured. The flight originated at the Redlands, California, airport on the day of the mishap at 0900 hours as a local area dual instructional flight.
