Narrative:

During descent to landing on the downwind leg while receiving vectors; the right bleed air leak caution light illuminated. I was pilot flying and the captain was pilot monitoring. We both realized this was a fairly serious caution message and I called for identify and cancel. He told me I had the radios and the aircraft while he ran the non-normal checklist. While he was running through the checklist I was given vectors to a base leg and then to final approximately 4 miles out from the runway; and cleared for a visual approach. He stated that his two reset attempts of the right bleed valves did not fix the problem and the next step of the checklist was to continue to the engine shutdown checklist. He advised that at this point in time it would be safest and make the most sense to just land due to our current position (on final about four miles out in visual conditions) and then shut the engine down upon landing. He asked if I agreed and I definitely did. It would have made no sense to either try and shut down an engine while on short final or discontinue the approach and shut the engine down then return for landing. I then informed him we were cleared for landing at this point and we configured and landed as normal. Upon exiting the runway we shut down the right engine immediately without incident. This was a system malfunction. I think our decision to continue and land made the most common sense. To try and have one pilot shutting down an engine during final approach would be unsafe; especially when the aircraft will be on the ground in two minutes. Had this happened even a few more miles out from the airport we would have continued on to the engine shut-down checklist; and declared an emergency.

Title: A SF340 Right Bleed Air Leak caution light illuminated on final approach. Because of the proximity to the airport and little time remaining to landing; the crew elected to leave the engine running until after safely on the runway.
