Cessna F177RG Cardinal RG, G-BFPZ
Summary:
The pilot made a visual overhead join for entry into a right hand circuit for Runway 26. On the downwind leg he extended the landing gear and observed that the DOWN AND LOCKED light illuminate and checked visually that the landing gears were extended. On final approach the pilot checked that the green DOWN AND LOCKED light was illuminated. On touchdown, which was gentle, the main landing gears folded rearwards and the aircraft came to a halt with the nose landing gear extended and the green DOWN AND LOCKED light still illuminated. An engineering examination found that both main landing gear DOWN AND LOCKED magnetic proximity switches were ‘stuck’ in their DOWN AND LOCKED positions due to a lack of lubrication and weak return springs. Two safety recommendations are made.
