Probable cause
The fatigue fracture failure of both main landing gear (MLG) legs during the landing roll, which resulted in the collapse and separation of both MLG legs.

Read the full NTSB narrative
The commercial pilot reported that, after an uneventful touchdown on the dry, gravel-surface runway, he felt a medium vibration as he applied the brakes. As the airplane continued the landing roll, both main landing gear (MLG) legs sheared off. The propeller impacted the runway, and the airplane came to rest on the bottom of the fuselage, which sustained substantial damage. A postaccident examination of the airplane revealed that both MLG legs failed due to fatigue cracking. The fatigue cracks were extended by intermittent overstress until the legs separated. The overstress extensions likely occurred during the accident landing or immediately before it because there was no corrosion of the crack surfaces.
