Incident: American B773 at Buenos Aires on Jul 22nd 2018, cabin pressure problems


An American Airlines Boeing 777-300, registration N736AT performing flight AA-900 from Buenos Aires Ezeiza,BA (Argentina) to Miami,FL (USA), was climbing through about FL110 out of Buenos Aires when the crew received indication of a problem by the cabin pressurization controllers and descended the aircraft back to FL100. After working the checklists the crew decided to return to Buenos Aires, descended the aircraft further, dumped fuel and landed safely back on Buenos Aires' runway 11 about 80 minutes after departure.

The flight is currently making headlines in Argentina because one of the passengers was the head of the International Monetary Fund who was returning to her office after talks with Argentina's government.
