Circumstances:
At 2150LT, while approaching Chongqing-Baishiyi Airport, the n°4 engine failed. Seven minutes later, it caught fire and later detached. Aware that he would not reach the airport, the captain decided to attempt an emergency landing when the airplane struck power cables and crashed on a hill located 5,7 km short of runway, bursting into flames. The aircraft disintegrated on impact and all 108 occupants were killed.
Probable cause:
It was determined that the n°4 engine right starter generator became so hot that the feathering oil tube was burnt. The oil tube burst upon feathering of the prop and the engine caught fire.
