NTSB Factual Report

The pilot said he was practicing stop-and-go landings. He had completed three landings and on the fourth wheel landing the aircraft began to pull to the right. He corrected with a little left brake, which appeared to stop the abrupt right pivot. Moments later the aircraft ground looped to the left. The right wing tip and right horizontal stabilizer were scraped and bent.

NTSB Probable Cause

The pilot's loss of aircraft control during a landing attempt, which resulted in an inadvertent ground loop.
