United’s New Premium 787 Grounded Again Over Reported TCAS Issue

Key Points:

• United Airlines’ brand-new premium-heavy Boeing 787-9 Dreamliner, aircraft N61101, has been grounded again due to repeated problems with its Traffic Alert and Collision Avoidance System (TCAS), a critical safety feature designed to prevent midair collisions.
• The aircraft was sent back to Boeing’s Moses Lake facility where both TCAS antennas were replaced, but after returning to service and operating several flights, it was grounded once more following a canceled return flight from London to San Francisco.
• This recurring issue with the TCAS on a newly delivered aircraft represents a significant reliability concern for United, especially since this plane is intended to be the flagship for its new “Elevated” premium cabin product.
• While Boeing and United have not publicly detailed the root cause, the repeated failure after attempted repairs raises questions about quality control and the resolution process for critical safety systems on new Boeing aircraft.
• United has responsibly grounded the aircraft to address the problem, emphasizing passenger safety, but the ongoing troubles could impact the airline’s longhaul product launch and highlight the need for a swift and thorough fix before the plane returns to service.
