GE is working with Angolan carrier TAAG to determine the root cause of two engine events on the airline's Boeing 777-200ERs, the manufacturer says.

One event, according the US National Transportation Safety Board (NTSB), occurred on 6 December. The board says the aircraft powered by two GE90 engines suffered a low pressure turbine failure in the number two engine after takeoff from Portugal's Lisbon International airport.

The flight crew performed a turn back and landed without any injuries.

NTSB says turbine blades were reported to have been expelled out of the back of the engine over a populated area.

Local news reports from the capital Luanda state that TAAG has now grounded its three 777-200ERs after an aircraft on 23 December experienced problems with the right engine shortly after takeoff from Luanda on a flight to Dubai.
