United's Flagship 787 Grounds Again Over TCAS Glitch

United’s first premium-heavy 787-9 (N61101), the launch aircraft for its Elevated cabin, has been grounded again after reports of a TCAS (Traffic Alert and Collision Avoidance System) issue. Boeing replaced TCAS antennas during a Moses Lake maintenance visit, but the aircraft returned to service only to be pulled from flight again, with a London-to-San Francisco leg canceled. United says safety is the priority while Boeing and the airline investigate whether the fault is a Boeing installation, software, or related component issue, and work to fully resolve it before returning the aircraft to long-haul service.

United’s Brand-New 787 Grounded Again After Fix, TCAS Troubles Persist

United Airlines’ freshly delivered Boeing 787-9 Dreamliner (N61101) has been grounded again due to persistent TCAS (collision avoidance) system problems. After emergency diversions and a late-June 10-day maintenance stint at Boeing’s Moses Lake facility to address TCAS antenna issues, the aircraft was returned to service on June 30, but a July 3 flight UA-939 was canceled as a precaution while troubleshooting continued. The incident highlights teething pains with a high-end new-aircraft rollout as United pushes its Elevated cabin program.
