Probable cause

The student pilot's improper decision to release the seat latch to adjust the seat position during taxi, which resulted in his inability to reach the rudder or brake pedals and a subsequent loss of directional control and impact with a ditch and fence.

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

The solo student pilot reported that, while taxiing to the runway for departure, he attempted to adjust the seat to get a "better view." When he released the seat latch, the seat moved aft, and he was unable to reach the rudder pedals or brake pedals with his feet. He added that he was unable to lean forward because his seat belt was secured. Subsequently, the airplane veered left, and he pulled the engine throttle to idle, but the airplane exited the taxiway into a ditch and struck a wire fence. The airplane sustained substantial damage to the left wing and right horizontal stabilizer. The student reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
