Narrative:

I made a normal stabilized approach and landing on runway 9L at opf airport. On rollout, the aircraft wxvaned to the right and I corrected with appropriate left rudder and then left braking. The left gear failed and the left wingtip and propeller struck the runway and the aircraft pivoted to the left. I turned off master and gas and exited the aircraft.
