FAA and NTSB Investigate Marine One Separation Incident
Federal aviation authorities are investigating a brief loss of required separation between Marine One, carrying President Donald Trump, and a commercial aircraft departing Ronald Reagan Washington National Airport on Tuesday, August 4, 2026.
The Federal Aviation Administration said its preliminary review found that the aircraft momentarily came within the prescribed separation limits before continuing away from each other. The agency said an air traffic controller remained in contact with both pilots throughout the event. It is reviewing whether a recently adopted safety protocol was violated and said it would take corrective action if warranted.
The National Transportation Safety Board separately announced Wednesday that it was investigating the reported loss of separation. Under FAA rules cited in reports, aircraft flying at the same altitude generally must remain at least three miles apart when operating within 40 miles of an Airport Surveillance Radar antenna. The precise distance between the aircraft during Tuesday’s incident was not disclosed.
The event occurred as Trump left the White House aboard Marine One for Joint Base Andrews. He was scheduled to continue to Los Angeles for a Republican National Committee fundraising event before traveling to Las Vegas for a rally on August 5.
White House spokesperson Kush Desai said Marine One was operated by highly trained aviators and that the president was never in danger. The FAA echoed that assessment in its statement. The U.S. Secret Service directed questions to the White House and FAA.
The investigations will examine communications, flight paths and compliance with applicable air traffic procedures. Neither agency had announced a cause or identified responsibility as of Wednesday. The findings could determine whether procedural changes, additional training or other safety measures are needed to reduce the risk of similar incidents in the heavily controlled airspace around Washington. Both agencies said their reviews remained in progress.
