A TAP Air Portugal Airbus A330-200, registration CS-TOO performing flight TP-85 from Lisbon (Portugal) to Sao Paulo Guarulhos,SP (Brazil) with 268 people on board, was climbing out of Lisbon's runway 03 when the crew declared Mayday and stopped the climb at 3000 feet reporting an engine (CF6-80E1/E2) failure. The aircraft subsequently climbed to 5000 feet and entered a hold. The aircraft dumped fuel and returned to Lisbon for a safe landing on runway 03 about one hour after departure.
Lisbon police reported debris off the aircraft damaged a number of vehicles in Camarate just north of the runway end.
The airline confirmed an engine malfunction, however said it was not an engine explosion.
A replacement Airbus A330-200 registration CS-TOH departed Lisbon with a delay of about 12.5 hours and is estimated to reach Sao Paulo with a delay of 12:20 hours.
The airline's chairman reported on Jul 16th that a high pressure turbine's vane, located just at the exit of the combustion chamber and thus taking the highest temperatures, came loose, a problem that was introduced during manufacturing of the engine.
