Narrative:

When I cycled the gear down on approach, I got 2 solid greens on the mains and a flickering green on the nose. So I recycled and then got a solid green. I recycled again to test it and received 3 solid greens. I concluded the gear were now down and locked and the flickering was due to a bad bulb. On rollout, the nose gear collapsed as the nose gear green went out. Callback conversation with reporter revealed the following information: reporter stated all gear indications were normal at touchdown. Reporter said the maintenance action taken was some sheet metal repair and a nose landing gear actuator rod replacement but the cause of the failure was not positively idented.
