On June 3, 2001, a Piper PA28 aircraft, piloted by Daniel Katz, 24, of Mexico, was en route from March Air Force Base in Perris to Brackett Field in Pomona when he went off radar about 7:30 p.m. in the Lytle Creek area of San Bernardino County while flying at about 2,900 feet. The 4,000-foot mountain range loomed directly ahead, and the plane is believed to have crashed in the area between Cucamonga Canyon and Lytle Creek.

That area where the plane is presumed to have crashed is within the D11 deer hunting zone. Archery hunting in D11 opened September 1, and general deer hunting opens September 22.

The airplane was brown and tan in color with a small orange strip along the fuselage. ID number is N8253W. Anyone coming across the aircraft should not disturb the scene, and should call the San Bernardino County Sheriff's dispatch at (909) 387-8313.
