FAA makes sweeping changes at one of the nation’s busiest airports after the National Transportation Safety Board urged “immediate action.”

The Federal Aviation Administration (FAA) on Friday announced it would permanently restrict “non-essential” helicopter operations around Washington, D.C.’s Ronald Reagan Washington National Airport (DCA),

Helicopter traffic should be permanently banned near Ronald Reagan Washington National Airport during certain periods to alleviate congestion and avoid a repeat of the deadly midair collision that occurred there in January,

The NTSB’s preliminary report on the Jan. 29 crash that killed 67 people said current helicopter routes allowed around the airport are an ‘intolerable risk to aviation safety.’

The transportation secretary’s decision came after the National Transportation Safety Board cited a long history of near collisions between helicopters and airplanes near the nation’s capital.

Federal investigators probing January’s fatal air collision near Ronald Reagan Washington National Airport have called for restrictions on military helicopters to make the area safer for commercial passengers.
