Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
The pilot reported that he experienced a mild bounce during landing and that touchdown after that was smooth, but the airplane drifted to the left. He applied right rudder and added brake to counteract the drift unsuccessfully. The airplane continued to swerve left, and the right main landing gear separated from the plane which resulted in substantial damage to the fuselage and right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
