The National Transportation Safety Board (NTSB) continues to investigate the mid-air collision between a PSA Airlines Bombardier CRJ700, operating for American Eagle, and a U.S. Army Sikorsky UH-60 Black Hawk helicopter. The incident occurred near Ronald Reagan Washington National Airport on January 29.
On February 4, the NTSB reported progress in recovering parts of the CRJ700 from the Potomac River with assistance from the Naval Sea Systems Command Supervisor of Salvage and Diving. Recovered components include sections of the wings, fuselage, cabin, cockpit, stabilizers, tail cone, rudder, elevators, TCAS computer, and quick access recorder.
The NTSB expects to release a preliminary report within 30 days of the crash. Updated information shows that air traffic control at Washington National is supported by POTOMAC Terminal Radar Approach Control (TRACON), which integrates data from multiple radar sensors and ADS-B data. At the time of collision, the Black Hawk was recorded at 300 feet on ATC displays.
