Probable cause
An overload fracture of the right main landing gear during the landing roll, which resulted in a nose over.
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 and flight instructor were practicing soft field landings on the turf runway. During the landing rollout, the right main landing gear collapsed and the airplane nosed over. The right landing gear was fractured completely around a weld where the gear attached to the spindle assembly. Metallurgical examination of the fracture revealed features typical of an overstress separation, with no evidence of fatigue cracking.
