The pilot reported during a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge that, "it was a simple gear-up landing, I forgot to put the [landing gear] switch down." He added that he was not wearing noise canceling headphones, and he reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. The left wing sustained substantial damage. The pilot reported in the NTSB Pilot/Operator Aircraft Accident/Incident Report, "no accident, as specified by NTSB for gear up landing, is admitted." ## Factual narrative The airplane touched down during landing with the landing gear retraced and skidded to a stop in grass about 140 ft. past the end of the runway threshold.
