The pilot was landing an Aeronca 7AC, on an unimproved 1,000-foot-long, 30-foot-wide, grass runway that was located at his residence. After touchdown, the airplane's right main landing gear struck a rock that was partially buried in the ground. The right main landing gear separated, and the right wing strut was bent. The pilot stated he did not experience any mechanical problems with the airplane. He reported about 3,525 hours of total flight experience.

NTSB Probable Cause Narrative

The pilot's failure to identify a partially buried rock in the landing surface of an unimproved grass runway, which resulted in an inadvertent collision during the landing roll.
