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 student pilot reported that, while hand-propping the engine, the engine started at full power, and the airplane jumped over the chocks and began moving in circles. Subsequently, to stop the airplane, an airport vehicle was driven into the airplane's tail. The airplane sustained substantial damage to the fuselage. The student reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The student recommended that better control of the throttle could have prevented the accident.
