The incident at Boston’s Logan International Airport happened about a week after a “close call” between a budget JetBlue flight and a Learjet which has prompted a separate Federal Aviation Administration (FAA) probe, Fox News reports.

“As a tow tug was pushing it back from the gate at Boston Logan International Airport, the right wing of United Airlines Flight 515 struck the tail of United Airlines Flight 267 around 8.30am local time,” the FAA said of Monday’s incident.

“Both aircraft were Boeing 737s that were scheduled for departure.

“The FAA will investigate.”

Airport owner Massport told Fox Business that the plane was being towed by United staff when the collision occurred.

A photo shared on social media by a passenger on-board showed one plane’s wing touching the tail of the other.

“Hey United our plane crashed, but it’s just a fender bender,” they wrote.

United Airlines did not immediately respond to a request for comment from Fox Business.

Last week, the FAA said it was investigating a “close call” between a Learjet and a JetBlue flight on Monday evening at Boston Airport.

In a statement to Fox Business, the FAA, citing a preliminary review, said: “The pilot of a Learjet 60 took off without clearance while JetBlue Flight 206 was preparing to land on an intersecting runway.

“An air traffic controller instructed the pilot of the Learjet to line up and wait on Runway 9 while the JetBlue Embraer 190 landed on Runway 4-Right, which intersects Runway 9,” the FAA said. “The Learjet pilot read back the instructions clearly but began a takeoff roll instead.”

The statement added: “[The] pilot of the JetBlue aircraft took evasive action and initiated a climb-out as the Learjet crossed the intersection.”
