DIAMOND AIRCRAFT IND INC DA 20-C1

Full Narrative

The solo student pilot of the Diamond DA 20-C1 had accumulated a total of 14 flight hours at the time of the accident. For his second solo flight, he received a flight release from his instructor to conduct touch-and-go landings. During the first takeoff on runway 23, the student added full power for the takeoff roll. As the front wheel began to lift off, the airplane drifted off the left side of the 150-foot wide runway. The left wing struck the runway distance sign marked "5," destroying the sign which was situated approximately 36 feet from the runway edge. The student "had no sensation of a collision," and conducted three touch-and-go landings and a full stop before he terminated the flight. The student told an investigator for the National Transportation Safety Board that the controller in the air traffic control tower asked whether the maneuver was intended to avoid a hazard on the runway. The student told the Safety Board that he replied to the controller that it was only a momentary loss of control. Damage to the wing, was discovered when the student returned the airplane to the flight school. The leading edge of the left wing was damaged from the landing light inboard for approximately 3 feet. The inboard end of the damaged area exhibited splintering and separation of composite finish, binder, and cloth layers. The underside of the wing had an approximate 6 inch diameter hole which also exhibited splintered layers of composite finish, binder, and cloth material. The manager of the flight school reported that there were no airplane malfunctions or mechanical failures either before or after the collision. The student indicated that the airport Automated Terminal Information Service reported winds to be from 210 degrees at 9 knots.
