"While waiting to take off on the runway at DCA just now, another plane struck our wing," he wrote. "Thankfully, everyone is safe. Just a reminder: Recent cuts to the FAA weaken our skies and public safety."
The FAA will investigate. American Airlines said both aircraft taxied to the terminal and were taken out of service to be inspected by maintenance teams. The damage was limited to a winglet on each aircraft.
Operations at the airport have come under intense scrutiny since a Jan. 29 fatal collision between an American Airlines regional jet and a U.S. Army helicopter, killing 67 people. The FAA said this week it installed a new management team to oversee air traffic control at Reagan National.
Senators last month pressed the FAA for failing to act on thousands of reports of helicopters in dangerous proximity to airplanes near Reagan National.
