Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

The pilot reported that during the landing roll, the right main landing gear wheel adaptor broke. The failure caused the pilot to lose directional control and the airplane subsequently overturned. Examination of the wheel adaptor disclosed evidence of torsional tensile overload. There was no evidence of fatigue.
