Accident: United B752 enroute on 19-Sep-24, TCAS resolution 2 passengers injured

On September 19, 2024, a United Airlines Boeing 757-200, operating flight UA-2428 from Newark to San Francisco, encountered a Traffic Collision Avoidance System (TCAS) resolution advisory while flying at an altitude of 38,000 feet over Wyoming. The crew responded to the advisory, which resulted in a maneuver that led to two passengers sustaining injuries—one seriously and another with minor injuries. The aircraft continued to its destination and landed safely on runway 28L in San Francisco. The Federal Aviation Administration (FAA) classified the incident as an accident. Although the FAA radar and ADS-B data did not show any altitude deviation at the time of the TCAS alert, there was a noted increase in speed from 389 knots to 500 knots during the incident. The situation has raised questions regarding the proximity of other aircraft and the nature of the TCAS activation, with discussions ongoing about the potential for smoother automated responses to TCAS advisories to prevent injuries in the future.
