A330-200 TAP085 Engine Failure 12/07/2014
Hello all, first post on this forum.Long time reader.
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.

Welcome Orge to World of PPRuNe,
When the engine shop has done it's post inspection of the engine internals they will/would have found that the loose nozzle guide vane (NGV), moving rearwards, would have touched the high pressure turbine (HPT) blades that were rotating at just below max speed for the aircraft climb.
That would have been close to an explosion. All the now detached turbine blades would have flown outwards with a great deal of energy and speed. The HPT blades would have certainly removed the adjacent blades of the low pressure turbine (LPT).
A view into the exhaust would have revealed a 'sack of broken metal pieces' and the turbine discs with the remaining segments of turbine blade stubs....
Interesting to hear that the NGV was considered loose from initial build, inspection procedures are so rigorous and demanding in this area of very high temperatures, speed and metal stress.
Certainly an engine change and possibly repairs needed to the pylon area damaged by the flying blades.....
