Nobody was injured.

A forging fold that was introduced during the manufacture of the right main landing, which resulted in a fatigue crack in the right main landing gear cylinder, and its subsequent failure during landing.

During landing touchdown, following a stabilized approach, the right main landing gear failed. The airplane remained controllable by the pilots and came to a stop on the runway, resting on its right wing. The DFW Fire Department arrived at the accident site in 35 seconds and, following communication between the airplane's Captain and Fire Department's Incident Commander, it was decided that an emergency evacuation of the airplane was not necessary. Examination revealed that the right main gear's outer cylinder had fractured allowing the lower portion of the gear (including the wheel assembly) to separate from the airplane. Research, examination & testing of the cylinder revealed that a forging fold was introduced into the material during the first stage of its forging process. The first stage is a hand operation, therefore the quality is highly dependent on the person performing the hand operation. Following the first landing, the forging fold became a surface breaking crack, due to the normal loads imposed during landing. Although growth of the fatigue crack was suppressed by crack blunting, high load landings resulted in growth of the fatigue crack. Subsequently, the landing gear failed when the crack had reached a critical length. Additionally, the airplane's maintenance records were reviewed and no anomalies were found.
