The student pilot was conducting a touch-and-go landing in a Piper PA-28-140, on runway 28, a 4,001-foot-long, 75-foot-wide, asphalt runway. After touchdown, the airplane veered to the left. The student pilot applied right rudder and brake; however, the airplane continued off the left side of the runway, across a grass area, and came to rest in a small ravine. The airplane sustained damage to the right wing, firewall, and nose gear. Postaccident examination of the airplane by a Federal Aviation Administration inspector did not reveal any mechanical malfunctions. Winds reported at the airport about 30 minutes before the accident, were from 170 degrees at 5 knots; however, the student pilot reported that she checked the automated weather observation via radio prior to landing, which reported winds from 140 degrees at 4 knots.
