Narrative:

On approach to san carlos airport (sql), the landing gear extension showed the right main gear light would not illuminate, and the red gear un-safe light was illuminated. Multiple attempts were made to retract and extend the landing gear. In accordance with the emergency checklist, the gear was lowered manually. The right main gear was not indicating down. I decided to request a low approach at oakland international airport. We contacted bay approach and were handed off to oak tower and cleared for a low approach to runway 29. After 2 low approachs the tower advised we had 3 wheels extended. We were cleared to land runway 27R. Upon touchdown, all 3 gear wheels were extended. We rolled out for approximately 2500 ft. When I applied the brakes the right main gear folded in-board. I pulled the mixtures to idle cut-off and feathered the right propeller. After aircraft came to a stop, I switched all electrical and fuel system off and exited the aircraft, in accordance with emergency procedures. Damage was to the right propeller, wing tip and horizontal stabilizer. There were no injuries. Callback conversation with reporter revealed the following information: callback to observer reporter 261328 revealed that he knew nothing further on the cause of the failure of the right gear of the C-310Q.
