WASHINGTON, May 18 (Reuters) - The head of the Federal Aviation Administration will tell Congress on Tuesday the agency failed to act on warnings prior to the January 2025 fatal collision between an American Airlines AAL.O regional jet and Army helicopter that killed 67 people near Reagan Washington National Airport.

"Our airspace system was providing warning signals prior to that tragic evening. The issue was not a lack of data -- it was a failure to translate that data into action," FAA Administrator Bryan Bedford will tell a U.S. Senate Commerce subcommittee in written testimony. "That is the gap we are urgently closing."
