## Analysis

According to the student pilot, she completed one solo full-stop landing in the traffic pattern before the accident sequence. She taxied the airplane back to runway, was cleared for takeoff, and advanced the throttle to full forward. Soon she realized that the left door was open and she attempted to close it. According to the flight instructor monitoring the solo flight, the airplane departed the left side of the runway, bounced once, the nose wheel struck the ground, and the airplane came to rest inverted. The airplane incurred substantial damage to the firewall and empennage. The student pilot reported there were no preexisting mechanical anomalies with the airplane.
