The Federal Aviation Administration (FAA) is investigating an incident on a United Airlines flight where two passengers were injured after the pilots responded to a midair collision warning. The incident occurred when the aircraft’s Traffic Collision Avoidance System (TCAS) triggered an advisory requiring immediate corrective action, leading to an abrupt maneuver. The FAA emphasizes that while the situation was serious, there was no actual loss of safe separation between the aircraft. However, the jolt caused injuries, highlighting the importance of following safety procedures.
