NTSB Factual Report

The pilot was landing at mid-day in bright sunny conditions after completing a practice instrument landing system (ILS) approach. The pilot reported that he extended the landing gear and flaps when he was about three miles from the airport. The airplane crossed the threshold of the runway and was just about to touchdown when he noticed that the landing gear green indicator lights appeared not to be illuminated. The pilot went to full throttle, and immediately raised the landing gear and flaps. During the go-around attempt the airplane settled and the propeller struck the runway. The pilot held full power and a nose high attitude as the airspeed decreased. The airplane struck obstructions on the side of the runway and came to rest upright approximately 3,000 feet down the 6,704 foot long runway. There was substantial damage to the left wing. The solo pilot was not injured. An inspection of the aircraft systems by a Federal Aviation Administration inspector revealed that the cockpit lighting dimmer switch was set to the “Night Dim” position.

NTSB Probable Cause

The pilot’s premature retraction of the landing gear and the flaps during landing. Contributing to the accident was the inadvertent dimming of the cockpit lighting, resulting in a perceived unsafe gear configuration.
