Incident Overview
While practicing touch-and-go takeoffs and landings, the student pilot's door suddenly opened. The student responded by retarding the throttles and applying the brakes. The certified flight instructor (CFI) assessed the situation and concluded that the aircraft could not safely continue the takeoff due to low airspeed and insufficient remaining runway. The CFI then assisted the student with directional control and braking action. Despite these efforts, the airplane departed the runway and impacted a dirt berm at the departure end.
Aircraft and Flight Details
The source does not specify the aircraft type, registration, date, location, or occupants beyond the student pilot and CFI. No injuries or additional damage are mentioned. Both the CFI and student pilot reported no discrepancies with the aircraft before or during the event.
Sequence of Events
The event occurred during a series of touch-and-go maneuvers. On one takeoff roll, the student's door opened. The student aborted the takeoff by reducing power and braking. The CFI quickly evaluated the situation and determined that stopping on the runway was not possible. She then provided assistance to maintain directional control and increase braking. The aircraft subsequently left the paved surface and collided with a dirt berm at the end of the runway.
