NTSB Releases Initial Findings on Deadly DC Mid-Air Collision

The January crash of an American Airlines jet and a US Army Black Hawk helicopter killed 67 people, making it the deadliest US aviation disaster since 2001.

The collision occurred on January 29 as the American Airlines regional jet was preparing to land at Ronald Reagan Washington National Airport, and the helicopter was conducting a routine training flight.
Investigators have recovered all major wreckage and black boxes from both aircraft, which are being analyzed to piece together the events leading to the crash.
Preliminary findings suggest the helicopter crew may not have heard air traffic control instructions due to a radio transmission overlap, and conflicting altitude data may have contributed to the collision.
The crash took place at an altitude of approximately 325 feet, above the 200-foot limit for the helicopter in the area, with the helicopter crew reportedly wearing night vision goggles at the time.
The NTSB has emphasized that the investigation is ongoing and a final determination of the cause will take over a year to complete.
