here is what an original 216 fan blade looks like after it breaks off and gets crunched on by the belt, pulley, and front cross member.

I was about 3,000 miles from home at the time, and luckily it did no damage to anything else, it was just laying on the cross member like it was placed there.

This was the temporary solution and worked fine until I found a replacement a few hours down the road.

The fan had a preexisting crack that I did not spot early on, then it finally finished cracking off.
Do check your old fans carefully for cracks between the rivet holes.
