The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The flight instructor on board stated that the student was performing the takeoff. As the airplane accelerated down the runway, it began to drift to the right. The instructor attempted to correct with left rudder and left brake, but the airplane still exited the runway to the right. While exiting the runway, the student attempted to takeoff and the instructor overrode the student’s actions to keep the airplane on the ground. During the aborted takeoff, the airplane impacted a steel-constructed segmented circle which resulted in substantial damage to the fuselage. The pilot reported that there were no mechanical malfunctions or anomalies that would have precluded normal operation
