Analysis

On final approach for landing, the pilot retracted the gear when he intended to actuate the spoilers. He landed with the gear retracted and slid into a fence at the end of the runway. The pilot reported that when the gear handle is in the down position, it is next to and about one inch below the spoiler handle. He also noted that in most gliders, the gear handle is located completely clear of the spoiler handle and/or it is of a different shape.
