这个不是唯一一架摔在中国的MD-11，1999年8月22日晚上，华航CI-642摔在了香港国际机场。所幸大雨和快速赶到的消防队员扑灭了机尾的大火，只有三名乘客死亡，297名乘客与15名机组人员幸存。
以下文字我就不翻译了：
At about 6:43 P.M. on 22 August 1999, B-150, a McDonnell Douglas MD-11, was making its final approach to runway 25L when Typhoon Sam was 50 km NE of the airport. At an altitude of 700 feet prior to touchdown a further wind check was passed to the crew: 320 deg/28 knots gusting to 36 knots, while maximum crosswind component limit for the aircraft was 24 knots. The crew neglected this and continued the landing. During the final flare to land, the plane banked on its right, landed hard on its right main gear and the no. 3 engine touched the runway. The right main gear and the right wing separated. The plane rolled upside down and skidded off the runway in flames. When it stopped, it was on its back and the rear of the plane was on fire, coming to rest on a grass area next to the runway, 1100 m from the runway threshold. The right wing was found on a taxiway 90 meters from the nose of the plane. As shown in photos of the aircraft at rest, the fire caused significant damage to the rear section of the aircraft but was quickly extinguished due to the heavy rain and quick response from rescue teams in the airport.
The final report of the accident blamed it mainly on pilot error; the commander’s inability to arrest the high rate of descent existing at 50 ft altitude on the radar altimeter. The descent rate at touch down was 18-20 ft/s. QAR information at the last 500 ft of the approach could not be recovered due to the interruption of the power supply at impact and it was stored in volatile buffer. Probable wind variations and the loss of headwind component, together with the early retardation of thrust levers led to a 20 kt loss in indicated airspeed just prior to touchdown.
Due to a severe weather situation in Hong Kong, the flight crew had prepared to divert the flight directly to Taipei if the situation at Hong Kong was deemed unsuitable for landing. Sufficient fuel was carried, resulting in a landing weight of 429557 lb, which is just 443 lb below its maximum landing weight. Approaching Hong Kong and after initial weather and wind check being passed from the airport, the crew believed that it could land there and thus decided against a diversion. Before the arrival of flight 642, four flights carried out missed approaches, five diverted and twelve landed successfully.
During the final approach, the plane descended along the ILS glideslope until at about 700 ft, when the crew gained visual with the runway, the crew disengaged the autopilot but left the autothrottle on. During the flare, the rate of descent was not arrested, the plane landed with the right wing slightly lower. The right landing gear touched down first, the right engine impacted the runway and the right wing was detached from the fuselage. Since the left wing was still attached to the plane, it rolled onto its right side, and the plane came to rest inverted in the grass strip next to the runway. The spilled fuel caught fire.
附近游客碰巧拍到了事故经过的视频。从背景声音中可以听到女声说到：“Let's see if it can make it, it's a bit shaky there.”男声予以肯定：“This guy is having a hard time.”
