2022 Boeing 777 Engine Component Separation Incident at Ezeiza (N-765AN)

Incident Overview and Flight Details On October 28, 2022, at 01:20 UTC, American Airlines flight AA908, operating a Boeing 777-200 with registration N-765AN, departed from Ministro Pistarini International Airport in Ezeiza, Buenos Aires Province, bound for Miami International Airport. The incident occurred during the takeoff roll, shortly before rotation, when fragments of the left engine's thrust reverser panel and exhaust nozzle separated. The damage was confined to the engine and affected components, with no impact on the aircraft's overall systems. ## Crew Response and Investigation Findings The flight crew, consisting of a pilot flying (PF), a pilot monitoring (PM), and a relief first officer, detected the issue when the left engine's fuel flow and engine pressure ratio (EPR) indications momentarily disappeared at 120 knots. Cabin crew subsequently reported seeing sparks and hearing noises from the left engine. After assessing the situation and maintaining controlled parameters, the crew declared an emergency at 3,000 feet and returned to Ezeiza, landing without further damage. The runway required cleaning due to separated internal engine parts, but no airport infrastructure was damaged. The National Transportation Safety Board (NTSB) read the flight data recorder, confirming that thrust parameters were correct throughout the flight phases. The affected Rolls-Royce Trent 892-17 engine was sent to the operator's facilities in Tulsa, Oklahoma, for further analysis. No injuries were reported among the 12 crew members and 256 passengers.
