Angolan carrier TAAG is working with General Electric to determine the root cause of two engine events on the airline's Boeing 777-200ERs.
One event, according to the US National Transportation Safety Board, was on 6 December. The board says the GE90-powered aircraft suffered a low-pressure turbine failure in the number two engine after take-off from Portuguese capital Lisbon. The flightcrew performed a turnback and landed without any injuries.
The NTSB says turbine blades were reportedly expelled from the rear of the engine over a populated area.
GE says it is working with the carrier, after local reports from Angola said that TAAG grounded its three 777-200ERs after another incident on 23 December involving a GE90 shortly after take-off from Luanda on a flight to Dubai.
