Aircraft involved

Probable cause & findings

The pilot's failure to extend the landing gear before landing, which resulted in a gear-up landing and a runway overrun.

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. The pilot reported during a telephone conversation with the 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 did not report any 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."
