Read the full NTSB narrative
The pilot and his instructor visually checked that the landing gear was down. On the landing roll the aircraft started to vibrate, and then rotated to the left. The instructor pilot shut down the engine and the right landing gear collapsed. The main gear actuator piston for the left main landing gear was found broken. A determination as to when the actuator piston was broken could not be made due to the extent of the damage. An examination of the aircraft logbook revealed that the main landing gear actuator piston had accumulated 1,530.2 hours since installation. The aircraft was examined on-scene with no further anomalies noted. An examination found beach marks on the fracture surface characteristic of a fatigue crack growth. The examination revealed that the fracture outside of the fatigue region was the result of a single event overload and not due to the fatigue crack.
