The Federal Aviation Administration said on Saturday that it was investigating a near miss between two planes at Boston Logan International Airport.
The episode happened at about 11:30 a.m., when Delta Air Lines Flight 2351 performed a go-around to avoid another plane that was taking off from an intersecting runway, the F.A.A. said in statement. The agency did not identify the other plane involved.
A go-around is a standard maneuver in which a plane aborts a landing, repositions and tries again. The F.A.A. said information around the episode was preliminary.
Data from Flightradar24, a flight-tracking website, showed that the Delta flight, arriving from Dallas, aborted its approach for landing as American Airlines Flight 3161, bound for Charlotte, N.C., approached from an intersecting runway.
The two planes were a few hundred feet apart, the tracking data showed. The Delta plane landed around 10 minutes later, according to the tracking data.
Delta said the flight crew received an advisory from an onboard system warning of potential traffic while the plane was descending and coordinated with air traffic control to perform the go-around. The plane landed safely and the passengers deplaned normally, according to a spokesperson for the airline.
The plane, an Airbus A319, was carrying 129 passengers and six crew members, the spokesperson said.
American Airlines did not immediately respond to a request for comment.
This was the latest in a string of near misses at U.S. airports in recent months. In April, an American Airlines regional jet flew dangerously close to an Air Canada regional jet after aborting its landing at Kennedy International Airport, according to the F.A.A.
The same month, the agency also investigated a close call between two Southwest Airlines jets at Nashville International Airport, in which an air traffic controller inadvertently directed an incoming plane into the path of a departing aircraft. The planes came within about 500 vertical feet of each other as the pilots reacted to onboard collision alerts, according to Flightradar24 and the F.A.A.
