(WASHINGTON) — The Federal Aviation Administration is looking into an incident, first reported by the Washington Post, in which three airplanes nearly collided midair at Reagan National Airport Tuesday afternoon.
The newspaper reported on Wednesday that an incoming US Airways jet that was cleared for landing ended up flying directly towards two departing US Airways jets after it had been rerouted. A storm that brought a change in wind patterns prompted air traffic controllers to reverse the flow of traffic around 2 p.m. Tuesday.
A collision was avoided — by about 12 seconds, according to the Post — between the inbound plane and the first of the two outbound planes when an air traffic controller recognized the mistake and ordered the inbound flight to change course.
The FAA, which was alerted to the near mishap by the newspaper, issued a statement Wednesday night explaining the situation.
“DCA (Reagan National Airport) had been landing and departing aircraft on Runway 1, from the south to the north. Due to the bad weather developing, the Tracon (Terminal Radar Approach Control) was switching operations to land and depart aircraft from the north to the south on Runway 19. During the switchover of operations, miscommunication between the Tracon and the DCA tower led to a loss of the required separation between two regional jets departing from Runway 1 and a regional jet inbound for Runway 19,” the FAA said.
“Preliminary information indicates that the closest proximity was 1.45 nm lateral and 500 ft. vertical for the first plane departing Runway 1 and 2.42 nm lateral and 600 ft. vertical for the second plane,” the agency noted. Standard separation requirements are 3 nm lateral and 1,000 ft. vertical.
The FAA said it was “investigating the incident and will take appropriate action to address the miscommunication.”
The National Transportation Safety Board, which was also made aware of the report, said on Wednesday it was in the process of gathering information to determine whether it too will launch an investigation.
US Airways, the airline reportedly involved in the incident, issued a statement saying it was looking into the matter and working with the FAA to determine what happened.
“The safety of our customers and employees is always our top priority,” the carrier said.
According to the Washington Post, 192 passengers and crew members were aboard the three planes.
