WASHINGTON (AP) — Federal investigators looking into the cause of the January collision between a passenger jet and an Army helicopter near Washington, D.C., that killed 67 people recommended a ban on some helicopter flights Tuesday, saying the current setup “poses an intolerable risk.”

National Transportation Safety Board Chairwoman Jennifer Homendy laid out frightening statistics about near misses to underscore the danger that has existed for years near Ronald Reagan National Airport and expressed anger that it took a midair collision for it to come to light.

In just over three years, she said, there were 85 close calls when a few feet in the wrong direction could have resulted in the same kind of crash that occurred Jan. 29 when the military helicopter collided with an American Airlines jet over the Potomac River as the plane was approaching the airport.

Transportation Secretary Sean Duffy said he’ll adopt the NTSB’s recommendations for the route where the midair collision occurred.

He noted there will be some modifications in the guidelines to be released Wednesday, including allowing presidential flights and lifesaving missions.

Helicopters no longer will be “threading the needle” flying under landing planes, he said.

The Federal Aviation Administration also will use artificial intelligence to analyze data from every airport to make sure there aren’t similar dangers elsewhere, he said, adding that there are other airports with cross-traffic.

Homendy and Duffy both said the hazards at Reagan airport should have been recognized earlier by the FAA.

“The data was there. It wasn’t effectively analyzed to see we had this risk,” Duffy said.

The NTSB determined that the existing separation distance between planes and helicopters at Reagan airport is “insufficient and poses an intolerable risk to aviation safety,” Homendy said.
