More than a month after an American Airlines plane and a Black Hawk helicopter collided near Reagan National Airport (DCA), killing 67 people, officials with the National Transportation Safety Board (NTSB) are calling for immediate changes to helicopter routes around DCA because they said it poses “an intolerable risk

The National Transportation Safety Board "urgently recommended" Tuesday that the Federal Aviation Administration permanently prohibit helicopter traffic near Reagan National Airport when two runways are in use following the deadliest aviation disaster in the U.

The NTSB is urging the FAA to take steps to ensure helicopter traffic is never permitted to cross arrival and departure paths at Reagan Washington National Airport (DCA), eliminating a risk that the board suggests should have been addressed before the Jan. 29 midair collision of a regional jet and a U.S Army helicopter.

The US Federal Aviation Administration detailed a series of restrictions on helicopter traffic near Ronald Reagan Washington National Airport following a deadly midair collision in January.
