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 pilot reported that he was approaching to land at his private airstrip and that he misjudged the airplane height above the runway and incorrectly relaxed back pressure on the control stick, which allowed the nosewheel to contact the runway before the main landing gear. The nose landing gear subsequently collapsed and the airplane nosed over. The airplane sustained substantial damage to the rudder and vertical stabilizer. The pilot noted that there were no preimpact failures or malfunctions with the airplane that would have precluded normal operation.
