sentences:  Beginning about 17 feet above the runway, the captain had let the nose lower, probably to achieve an earlier touchdown, then raised it and increased thrust to slow the plane's descent, then pushed the nose down again (around the time of the first touchdown) to try to keep the plane on the runway.These last control inputs were "too late and too large" to stabilize the landing, and the plane's high sink rate and rightward roll compressed the right landing gear strut at the second touchdown, which broke the right wing rear spar and ruptured the right fuel tank.As a result of its investigation of this accident, the NTSB made new recommendations based on their findings and conclusions to improve the safety of operations of the MD-11 type aircraft including that the FAA develop new pilot training tools to "include information about factors that can contribute to structural failures involving the landing gear, wings, and fuselage, such as design sink rate limits; roll angle limits; control inputs’ roll rate; pitch rate; single-gear landings; the effect of decreased lift; and structural loading consequences of bottoming landing gear struts and tires; provide a syllabus for simulator training on the execution of stabilized approaches to the landing flare, the identification of unstabilized landing flares, and recovery from these situations, including proper high sink rate recovery techniques during flare to landing, techniques for avoiding and recovering from overcontrol in pitch before touchdown, and techniques for avoiding overcontrol and premature derotation during a bounced landing; and to promote an orientation toward a proactive go-around."
