Analysis

The pilot stated that he had landed to the south in light and variable winds in visual meteorological conditions. The airplane swerved to the right; he overcorrected, and the airplane ground-looped to the right, collapsing the right main landing gear and striking the right wing, bending the rear spar. In a written statement, the pilot noted that he 'realize[d] that I had landed a little hot and had not completely stalled. I had relaxed back pressure on the elevator and had not planted my tailwheel. I feel that fatigue and a lack of attention to the job at hand caused this accident.' He additionally noted that 'I had been working the graveyard shift for the past seven nights and I was very tired. I should have gotten a few hours of sleep before the flight.'
