Circumstances:
The approach to Zhanjiang Airport was completed in poor weather conditions with thunderstorm activity, heavy rain falls and strong winds. Following a wrong approach configuration, the aircraft passed over the runway threshold at a too high altitude of 400 metres. The pilot-in-command increased the rate of descent when the aircraft landed hard and bounced. It floated for about 330 metres then landed 15 metres to the right of the runway. Out of control, it lost its undercarriage and came to rest few dozen metres further. All 90 occupants were rescued, among them six passengers were injured.
Probable cause:
Loss of control upon landing following a wrong approach configuration. The following contributing factors were identified:
- Poor approach planning,
- Poor crew coordination,
- The crew failed to follow the approach checklist,
- The crew failed to set the correct QNH on approach,
- The aircraft was too high on approach,
- Poor weather conditions,
- The crew failed to initiate a go-around procedure.

Circumstances:
The approach to Shenzhen-Huangtian Airport was completed in poor weather conditions with thunderstorm activity, heavy rain falls and turbulences. During the last segment, the aircraft was unstable but the crew continued the descent when the aircraft landed hard. The aircraft bounced and suffered undercarriage damages. Despite the situation, the captain decided to initiate a go-around procedure and increased engine power. During the second attempt to land, the crew encountered control difficulties as the aircraft suffered damages from the first missed landing. Also, weather conditions were poor so the aircraft was unstable on approach. After landing at an excessive speed, the aircraft went out of control, veered off runway and came to rest in a soft ground, broken in three and bursting into flames. Two crew members and 33 passengers were killed while 39 other people were injured.

Circumstances:
At a distance of 40 km from the airport, at an altitude of 7,800 feet, the crew was cleared to make a visual approach and to descent to 7,000 feet. Three minutes later, the aircraft went out of control and crashed on a mountain slope (1'600 metres high) located 27 km south from runway 36. The aircraft was totally destroyed and all 141 occupants were killed. It was reported that the captain attempted to level off the plane by raising its nose. The autothrottle responded by advancing the throttles. The n°2 power lever however remained at idle. The crew apparently did not notice this. With the right engine at idle, the autothrottle further advanced the left engine power lever in order to obtain the correct airspeed. The asymmetrical power condition was not corrected and the airplane rolled to the right and crashed.
