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 was on a personal local flight, operating under Title 14, Code of Federal Regulations Part 91. The pilot reported that during landing, the airplane landed hard, and bounced back into the air. He said he added power to go around, but the airplane drifted left of the runway, and the right wing struck a signpost. He said the airplane spun around the post, and impacted the ground. The pilot said there were no preimpact mechanical problems with the airplane, and that the airplane sustained substantial damage to its right wing.
