An NTSB-led investigation is in full swing to identify factors that led to the Jan. 29 midair collision between an American Eagle Bombardier CRJ-700 operated by PSA Airlines on approach to Ronald Reagan Washington National Airport (DCA) and a U.S. Army Sikorsky UH-60L Black Hawk helicopter.

An American Airlines flight crashed into a U.S. Army Black Hawk Helicopter over the Potomac River as it approached Ronald Reagan Washington National Airport.

There was a mid-air collision between a commercial airliner and a Sikorsky H-60 Black Hawk helicopter Wednesday night over the Capital Region. “The FAA and NTSB will investigate,” the statement added.
