A Delta flight making its final approach from LaGuardia Airport in New York to Logan International Airport was waved off and redirected Thursday because another plane taxied onto the runway without clearance, aviation officials said.
The Federal Aviation Administration said the airliner landed safely after 4 p.m.
“Air traffic controllers at Boston Logan International Airport directed an Airbus 319 on final approach to Runway 4R to follow a missed approach procedure and go around for another landing,” the FAA said. “Controllers took the precautionary action because a Boeing 737 had taxied across the end of the same runway without air traffic authorization.”
An aviation official with knowledge of the incident who requested anonymity because of not being authorized to speak on the matter said the plane that was forced to change its landing path was Delta Flight 1386 and the jet that crossed the runway was American Airlines Flight 349. The Delta airliner was coming from New York, and the American Airlines jet was about to take off for Dallas-Fort Worth.
The FAA did not say how close the two planes came to each other. No one was injured in the incident.
Dori Alvarez, an American Airlines spokeswoman, confirmed Thursday night that the company was investigating an incident that occurred with Flight 349 at Logan. She said that 144 passengers and five crew members were unharmed, and that the plane took off as scheduled. Alvarez said she could not discuss details of the investigation.
Delta Air Lines could not be reached for comment Thursday night. The airline’s online tracker showed that Flight 1386 left LaGuardia Airport at 2:08 p.m. and landed in Boston at 4:06 p.m., almost an hour after its scheduled arrival.
