The pilot reported that the tire was good during his preflight inspection. Postaccident examination of the tire revealed no evidence of a failure to identify the reason why the tire went flat. ## Factual narrative The pilot reported that during landing, the airplane's left main landing gear tire went flat, which resulted in the left wingtip contacting the ground and substantially damaging the left aileron.
