Incident Summary
At dusk, during arrival, the pilot attempted to lower the landing gear but did not observe a gear-down light indication. He recycled the landing gear several times and then utilized the emergency gear extension system. The pilot stated that when he used the extension system, he released the electric gear motor and then extended the telescopic emergency arm rearward. However, the arm should have been in the forward position to lower the gear.
Pilot Actions
The pilot noted that when the navigation lights were turned on, the green gear-down and amber gear-up lights would have automatically dimmed. After the landing gear extension attempt, the pilot landed the aircraft. Upon touchdown, the landing gear collapsed, and a fire erupted. The aircraft was destroyed.
Findings
During the investigation, no pre-accident part failure or malfunction was found. The incorrect positioning of the telescopic emergency arm contributed to the gear not being properly extended.
