ATLANTA — Sandy Springs-based UPS announced that it is retiring its fleet of MD-11 model planes – the same model of plane that crashed at the Louisville, Kentucky airport in November. UPS held its fourth-quarter investor call on Tuesday, where CEO Carol Tomé said the planes will be replaced.

The business jet that crashed Sunday evening while trying to take off in a snowstorm in Maine and killed at least a half dozen people is a plane model that has a history of problems with crashes caused by ice buildup on the wings.

An aviation consultant said the Bombardier Challenger 600 is "very susceptible" to ice contamination in the upper wing.

The FAA reported seven people have died and one person is seriously injured after a plane linked to Houston law-firm Arnold & Itkin crashed in Maine.

The FAA said the aircraft went down during departure and was later consumed by a post-crash fire.
