You could see how hard it was on the starter, and they never even got it running again, at least in the video. Based on the narration, I assume they eventually did.

If the accum. was working, as soon as the prop lever was moved up out of the feather position, the oil pressure in the accum. would move the blades to their normal operating position, which would force the prop to start windmilling. Engine is spinning at this point, ready to start, without ever touching the starter. Just get the throttle/mixture setting correct, and it will fire right up!

I read you have to service the nitrogen in the accumulators every 90 days. Seems as if theirs had not been serviced recently. So glad I have my own nitrogen tank for servicing struts, would work for the accum. as well.
