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, after landing, the nose landing gear began a “severe shimmy” and subsequently fractured. The propeller contacted the runway, and the engine mounts sustained substantial damage. The airplane was not made available for examination following the accident, and the source of the shimmy could not be determined based on the available information.
