This isn't a new phenomenon. Back in the '70s DC-10s were in a number of crashes and as a result an emergency AD was issued to ground them.

TWA had a fleet of L1011s and painted the aircraft model on all of them because people were concerned that they were getting on one of those dangerous three engined aircraft.

And for all the Tprop bashers: 250 below 10,000 is the same in both types. No reason to use jets on ORD-MKE, PIT-IAD etc.
