A THY Turkish Airlines Airbus A330-300, registration TC-JOB, was climbing out of Istanbul’s runway 36 on flight TK-42 from Istanbul (Turkey) to Johannesburg (South Africa) when the crew stopped the climb at about 6000 feet when the left-hand engine (CF6) emitted a number of bangs.
The engine was switched off. The plane entered a hold to burn off fuel before returning to Istanbul for a safe landing on runway 35R at 4:25 p.m.
A replacement A330-300, registered TC-JNK, departed Istanbul around 5 hours after TC-JOB landed and is expected to arrive in Johannesburg at 9:45 a.m.
According to a passenger, the left engine emitted large booms and streaks of flames through the engine inlet for around 20 seconds.
After some time, the captain declared that they would be returning to Istanbul due to a technical issue and would be holding to burn off fuel.
