On May 31, 2000, at 1536 hours Pacific daylight time, Piper PA-28-140, N6349W, overran the runway and nosed over while taking off at Long Beach, California. The aircraft sustained substantial damage and the certificated flight instructor and student pilot received minor injuries. The aircraft was being operated as an instructional flight by Ray's Flying Club, Inc., under 14 CFR Part 91 when the accident occurred. The flight originated at Fullerton, California, at 1420. Visual meteorological conditions prevailed at the time and no flight plan was filed. The instructor reported that he and the student had completed the landing portion of a touch-and-go takeoff and landing on runway 25L. He now planned to depart the area and told the student to add power for takeoff. As the aircraft speed increased, he noted that the aircraft was drifting to the right. He told the student to correct with left rudder. When the drift continued, he attempted to take over the controls but the student did not relinquish the controls and the flight instructor was unable to override his control input. The aircraft continued off the right side of the runway, the nose gear collapsed, and the aircraft nosed over, coming to rest in an inverted attitude. Winds at Daugherty Field were reported as 190 degrees at 10 knots.
