Narrative:

After a normal landing and rollout; we slowed to our normal taxi speed and began to exit runway xx on taxiway xx when the left main gear collapsed. I executed an emergency shutdown procedure as the aircraft skidded a short distance before coming to a stop on taxiway xx. We exited and secured the aircraft. There were no injuries.
