On August 24, 2018, about 2350 eastern daylight time, Aer Lingus flight 114, a Boeing 757-200, EI-LBT, had a ground service employee suffer a serious injury while engaged in pushback from the gate at Philadelphia International Airport (KPHL), Philadelphia, Pennsylvania. There were no injuries to 177 passengers and crew onboard. The airplane was not damaged. The flight was operated as a Title 14 Code of Federal Regulations Part 129 scheduled international passenger flight from KPHL to Dublin Airport (EIDW), Dublin, Ireland. According to the operator, the ground service employee was connected to the airplane via a headset and was engaged in push-back from gate A6. At some point, the service employee fell down and the nose wheel ran over his right leg, causing a serious injury. The flight crew reported that the pushback was nearly complete and were about halfway through the 90 degree turn onto the taxi line, when the airplane jerked to a stop. There was general confusion for several minutes before they were informed of what happened.
