NTSB Factual Report

The pilot reported that he extended the landing gear while in the traffic pattern. He added that he became distracted by a helicopter that was transitioning the airport, and while on base to final approach, he mistakenly raised the landing gear. The airplane subsequently touched down with the landing gear retracted.

The fuselage sustained substantial damage.

The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

NTSB Probable Cause

The pilot’s distraction before landing by a helicopter that was transitioning to the airport and his subsequent failure to extend the landing gear before touchdown.
