Canadian news media report today that the fuel starvation that forced an Air Transat A330 to make a dead-stick landing may be attributable to a cracked fuel pipe in the No.2 RR engine. The right-hand engine was replaced recently, and an inspection after the forced landing has disclosed that not enough space existed between the fuel pipe and a hydraulic pipe in the engine. If the two pipes rub together, cracks in the fuel pipe can result. This in turn may have been the cause of the fuel starvation.
RR had earlier issued a Service Bulletin to address this situation, but the SB had apparently been only "partially" applied to the Air Transat A330 No.2 engine.
The subtle finger-pointing has begun, with Air Transat and RR / Airbus each staking positions in the media to manage public opinion to their own benefit.
