LOUISVILLE — A UPS cargo plane aborted its landing at Louisville's Muhammad Ali International Airport around 12:10 a.m. local time Tuesday after a Labcorp plane moved past the hold short bars of runway 17 as the cargo jet approached. No one was hurt.

The Labcorp plane had been on a taxiway and was instructed to hold short of the runway to allow the UPS flight to land. When the Labcorp pilot moved the aircraft past the hold short bars, alarm systems in the control tower were triggered.

An air traffic controller yelled "Skylab 25, stop!" at the small plane, and the Labcorp aircraft complied. The controller then ordered the UPS plane to pull up and perform a go-around maneuver. The UPS plane was about 125 feet above the ground at that point. Audio of the exchange was posted online by LiveATC.net.

The UPS pilot told controllers that the crew had been unable to communicate with the Labcorp pilot and had planned to perform a go-around before receiving the order. An air traffic controller then said, "And everybody gets to go home at night."

According to data from FlightRadar24, the Labcorp plane never entered the runway. The Federal Aviation Administration said the two planes maintained "required separation."

In a statement, UPS said its pilot was acting "in accordance with standard procedures" and that there was "no operational impact" from the incident. Muhammad Ali International Airport is a major hub for UPS.

Last November, a UPS plane crashed at the airport after an engine fell off as it was rolling down the runway to take off, killing 14 people. The National Transportation Safety Board announced Thursday that it plans to hold two days of investigative hearings starting May 19 to examine that crash.

Other recent runway and taxiway incidents have occurred at U.S. airports. Last week, a Frontier Airlines jet nearly collided with two trucks that crossed in front of it as it taxied at slow speeds at Los Angeles International Airport. In a separate incident in Charlotte, North Carolina, an American Airlines pilot told the tower he had to slam on the brakes when a truck crossed in front of him on a taxiway. An Air Canada plane landing at LaGuardia Airport in New York smashed into a fire truck that had been cleared to cross the runway less than 20 seconds earlier, killing both pilots and injuring dozens of people.
