White House Construction Played a Role in Presidential Helicopter Incident
Security officials reported that the relocation of the helipad due to construction work at the White House contributed to a dangerous close call between Marine One and an airliner.
In a preliminary report released by the National Transportation Safety Board, it was disclosed that the relocation of the helipad due to construction work carried out during Donald Trump's term and communication issues played a role in the incident where the presidential helicopter Marine One approached an airliner.
Construction Work and Relocation of the Helipad
In May, helicopter flights were moved from the South Lawn to the nearby Ellipse area due to ongoing construction work at the White House. The projects underway include a new ballroom planned to replace the East Wing and a new helipad for Marine One.
Details of the Critical August 4 Incident
During the incident on August 4, the Marine One crew attempted to make the required three-minute departure notification to air traffic controllers via radio at least twice but failed to establish communication. This situation resulted in commercial flights not being halted and a loss of separation between the aircraft and the helicopter.
Aviation Rules and Separation Values
Air traffic rules require aircraft to maintain a distance of at least 1.5 miles horizontally and 500 feet vertically around airports. The relevant report stated that Marine One and the airliner were at one point 0.82 nautical miles apart horizontally and 700 feet apart vertically.
Measures Taken and New Developments
Federal Aviation Administration head Bryan Bedford stated that following the incident, an antenna was relocated and procedures were changed. It was reported that subsequent checks revealed no further communication issues.
