MONTREAL, Nov 8 (Reuters) - The Federal Aviation

Administration has issued an order prohibiting the flight of

MD-11 planes, pending inspection, following a fiery crash

earlier this week of a UPS MD-11 cargo freighter in

Louisville, Kentucky.

UPS and FedEx ( FDX ) said on Friday they have grounded

their combined fleet of more than 50 McDonnell Douglas MD-11

cargo planes following a recommendation by Boeing ( BA ), after

the crash on Tuesday at a Kentucky airport killed at least 14

people.
