The right wingtip of an Atlas Air passenger Boeing 747-400 hit the horizontal stabiliser of a Miami Air International 737-800 at Baltimore/Washington International Thurgood Marshall airport on 7 January.
The Federal Aviation Administration confirms the collision, which it says occurred at about 22:15 local time as the Atlas aircraft was taxiing for departure.
The FAA, which is still investigating, says the Miami Air 737 was parked at the time it was hit.
"It appears the winglet of the 747 made contact with another aircraft. All passengers and crew on both aircraft are safe and without injury," Atlas says in a statement to FlightGlobal. "We are continuing our investigation and cooperating with the FAA."
Atlas does not identify the exact aircraft, but Flightradar24.com shows that 747-400 registration N465MC was in Baltimore on 7 January.
Charter carrier Miami Air International did not respond to an inquiry from FlightGlobal. The carrier operates seven 737-800s, and two of those aircraft – registration N732MA and N750MA – were in Baltimore around 7 January.
Atlas Air is a subsidiary of charter and cargo carrier Atlas Air Worldwide Holdings, based in Purchase, New York.
