Narrative:

I was the captain on flight with the first officer flying. The landing checklist was completed with the gear down and locked including '3 green, no red' and 'hydraulic pressure's good' call outs. Upon landing, the left main gear folded up and the left propeller of the aircraft began striking the runway. Advancing the power levers produced vibration that was prohibitive, so the airplane was allowed to settle on the left wing and propeller which took us off the runway to the left and we stopped between the runway and parallel taxiway. There were no injuries and damage to the airplane has been called minimal.

Narrative: I WAS THE CAPT ON FLT WITH THE FO FLYING. THE LNDG CHKLIST WAS COMPLETED WITH THE GEAR DOWN AND LOCKED INCLUDING '3 GREEN, NO RED' AND 'HYD PRESSURE'S GOOD' CALL OUTS. UPON LNDG, THE L MAIN GEAR FOLDED UP AND THE L PROP OF THE ACFT BEGAN STRIKING THE RWY. ADVANCING THE PWR LEVERS PRODUCED VIBRATION THAT WAS PROHIBITIVE, SO THE AIRPLANE WAS ALLOWED TO SETTLE ON THE L WING AND PROP WHICH TOOK US OFF THE RWY TO THE L AND WE STOPPED BTWN THE RWY AND PARALLEL TXWY.
