Abstract: At approximately 5:15 a.m. on February 21, 2014, Employee #1 was operating a cargo MA Tug Technologies tow tractor (Model Identification RT-149, Serial Number 17978) at an international airport. He drove the cargo tow tractor from the storage area at an international terminal to a warehouse. Employee #1 lost control of the tug near a fire station on the airport. The cargo tug struck a 7.5 inch high curb, ejected him the tow tractor. Employee #1 was not wearing a seatbelt, as a portion of the seatbelt was missing from the tow tractor on the day of the accident. He was found pinned under a rear drive tire of the tow tractor and had sustained unspecified blunt force injuries. Evidence suggests that Employee #1 had died from a heart attack while driving the tractor tug.
