Abstract: On January 18, 2005, Employee #1, a service provider, was giving direction to a truck driver who was backing into a loading dock located just inside the building. Employee #1 worked for a manufacturer of large commercial and military aircraft. Employee #1, who was operating a YALE MTR-700 tug, serial number 5-0623, commonly called a "Mule" by employees, parked the vehicle in the path of the backing truck. The Mule is used to tow, in a train like fashion, small cars filled with parts used to build airplanes. The truck struck the "Mule," damaging the steering mechanism. Employee #1 and coworker tried to fix the broken steering mechanism by the coworker pushing and Employee #1 pulling the wheel. Just as they began to push and pull Employee #1 put his right hand into the pinch point at the pivot or hinge between the body of the "Mule" and the steering mechanism. Employee #1 suffered an amputation of his right middle finger when the finger was caught in the pinch point between the handle and body of the machine. The employee was hospitalized.
