Close calls between two commercial jets at Lagardia Airport in New York earlier this month are under investigation, the Federal Aviation Administration and the National Transportation Safety Board confirmed Monday.
The incident is one of many close calls that prompted the call to change in air travel in the United States and has raised public unrest about flight.
At about 12:35am on May 6, air traffic controllers cancelled the takeoff clearance for the American Eagle Flight 4736, operated by Republic Airlines.
“Brickyard 4736 Stop,” the tower controller cried using Republic Airlines Callign.
“We refused takeoff runway 13,” the pilot replied with audio recorded by website liveatc.net.
“I'm sorry, but I thought United had cleared quite a bit before that,” replied the controller.
The United Flight, operating on the Boeing 737-800, arrived from George Bush Intercontinental Airport in Houston that night, carrying 107 passengers and six crew members, the airline said Monday.
According to an analysis by tracking site Flightradar24, the plane was almost a quarter mile away when the Republic's flight hit the brakes.
The FAA also said Monday it was investigating another radio outage at the Air Traffic Approach Management facility, which is responsible for flights departing close to Newar Liberty International Airport.
The near call and halt is the latest in a string of failures that have occurred in recent weeks, just before the summer travel season.
The Newarctor Turminal Radar Approach Control Facility, also known as Philadelphia Tracon Area C, experienced a radio outage for about two seconds at around 11:35am Monday, according to the FAA.
The Philadelphia Tracon Area C issue has grown beyond New Jersey Airport and has announced serious issues within the FAA's outdated air traffic control system.
Despite the challenges, Department of Transport officials say the system is safe.
