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 private pilot reported that, while landing following a personal flight, when the nosewheel contacted the runway, the airplane veered to the right and off the side of the runway. The airplane continued down a grass hill and impacted a wood beacon pole. The airplane sustained substantial damage to the right wing spar. The pilot reported the nosewheel landing gear was turned to the right when it touched down on the runway. A Federal Aviation Administration inspector reported that a postaccident examination showed no preaccident mechanical failures or malfunctions with the nosewheel that would have precluded normal operation.
