Probable cause

The pilot's improper rudder inputs and failure to maintain directional control during landing with a crosswind, which resulted in a runway excursion and impact with a runway sign.

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 landed the airplane right of the runway centerline and that it then continued to drift right. He added right rudder, and the airplane continued to the right. He said that he "over-corrected back." The airplane subsequently exited the runway to the right and impacted a runway sign. The pilot taxied to parking without further incident. The airplane sustained substantial damage to the right elevator. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The airport's automated weather observation station reported that, about 7 minutes before the accident, the wind was from 150° at 6 knots. The pilot landed the airplane on runway 03.
