Army knew of Black Hawk altitude errors years before DCA crash, NTSB finds

Federal investigators revealed Wednesday that the Black Hawk helicopter involved in the deadly DCA crash may have misreported its altitude by more than 100 feet, a flaw the Army had long known about but never formally documented.

The testimony, delivered during the first day of a multiday National Transportation Safety Board (NTSB) hearing, raised fresh concerns about whether Army pilots were given the information needed to safely navigate controlled airspace. The January collision between a UH-60L Black Hawk and an American Airlines jet killed 67 people, making it one of the deadliest air disasters in recent U.S. history.
