On July 26, 2011, a C.A.L. Cargo Airlines Boeing B747-230F took off from Liège Airport (LGG)Belium and during the initial climb, about 1000 feet above the ground, the crew heard a loud noise (bang) in the No. 2 (inboard left) engine, a GE CF6-5E2 turbofan engine. The crew reported along with the loud bang in the No. 2 engine, a reduction of N2 (low pressure rotor speed) and a sharp rise of EGT (exhaust gas temperature) was observed. The crew shut down the engine,dumped fuel,and returned to land at Liège with no further incident. Initial inspection of the No. 2 engine revealed metal debris (fractured pieces of turbine blade and vane material) in the tailpipe of the engine. The investigation is under the jurisdiction of the Israeli Ministry of Transport. The Ministry of Transport has requested assistance from the NTSB in this investigation.
