Sun Way Flight 4412 was an international scheduled cargo flight from Karachi, Pakistan, to Khartoum, Sudan. On 28 November 2010, the Ilyushin Il-76 operating the flight crashed while attempting to return to Karachi after one of the engines catastrophically failed shortly after take-off. Twelve people were killed in the crash: everyone on board the aircraft and four people on the ground. The engine failure was caused by metal fatigue resulting from operation of the engine beyond its design life.
