The pilot added right rudder to correct back to the centerline, however, it continued toward the right side of the runway. The airplane subsequently went off of the runway and impacted a taxiway sign, which resulted in substantial damage to the rear right wing spar. A postaccident examination of the airplane by a Federal Aviation Administration aviation safety inspector revealed no preimpact anomalies that would have precluded normal operation. ## Factual narrative After touching down the airplane veered to the left.
