What happened
The incident occurred while a student pilot was conducting his second solo flight at an airport. The pilot's objective was to practice landing procedures by executing three full-stop landings, with each maneuver requiring taxiing back to the runway threshold for the subsequent takeoff.
During the preparation phase for the third solo takeoff attempt, the pilot failed to raise the flaps. As the aircraft accelerated down the runway, this configuration error caused the airplane to drift to the left side of the pavement. The aircraft subsequently struck a runway sign and continued off the paved surface into the grassy area adjacent to the runway. This impact resulted in damage to the wing.
The investigation
Examination of the event revealed that the primary mechanical factor was the position of the flaps during the takeoff roll. The pilot did not raise the flaps prior to initiating the takeoff, which contributed to the leftward drift and subsequent departure from the runway environment.
Findings
The sequence of events indicates a failure in pre-takeoff checklist execution or configuration awareness by the student pilot. The unretracted flaps altered the aircraft's handling characteristics during the critical takeoff phase, leading to the loss of directional control and the collision with the static infrastructure.
