Sequence of events

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

Following an uneventful flight and taxi back to the runway, the student pilot reported that when he applied takeoff power, the airplane began to veer to the left. He applied right rudder, but the control input was ineffective. He then reduced the power to idle and applied both brakes, but the airplane exited the left side of the runway and came to rest in a drainage ditch. The pilot was uninjured, and the airplane sustained substantial damage to the fuselage and empennage. Postaccident examination by a Federal Aviation Administration inspector revealed no evidence of any preimpact mechanical malfunctions or failures with the flight controls, braking system, or the nose wheel that would have precluded normal operation.
