The Federal Aviation Administration is looking into a collision at Chicago O’Hare International Airport over the weekend.

The collision took place Sunday evening when an All Nippon Airways plane, a Boeing 777, was on the ground preparing for takeoff when its left wing struck the stabilizer of a Delta Air Lines plane, a Boeing 717. The collision occurred in an area not under air traffic control, according to the FAA.

No injuries were reported from the incident.

The collision occurred shortly after another ANA plane was forced to turn back to its departure airport in Japan after a crack was discovered in the Boeing 737’s cockpit window. A spokesperson for the airline said the crack did not affect the flight’s control of pressurization.

Earlier this year, Alaska Airlines Boeing 736 Max 9 had to make an emergency landing in Portland, Oregon, after a midair door plug blow-out left a hole in the aircraft’s left side. Six passengers are suing Boeing for damages, as the event “physically injured some passengers and emotionally traumatized most if not all aboard,” according to the lawsuit.

The government is investigating the midair door plug blow-out, with the focus being on the plane’s “plug”-type passenger doors and other discrepancies.
