Aircraft Crash at Chongqing-Baishiyi Airport (B-222)

Incident Overview and Sequence of Events At 2150 local time, an aircraft was on approach to Chongqing-Baishiyi Airport when its number 4 engine failed. Seven minutes after the failure, the engine caught fire and subsequently detached from the airframe. The captain determined that the aircraft would not be able to reach the airport and attempted an emergency landing. During the approach, the aircraft struck power cables and crashed on a hill located 5.7 km short of the runway. The aircraft burst into flames and disintegrated on impact, resulting in the deaths of all 108 occupants on board. ## Official Probable Cause The official investigation determined that the right starter generator of the number 4 engine became excessively hot, causing the feathering oil tube to burn. When the propeller was feathered, the damaged oil tube burst, leading to an engine fire.
