What happened
During an approach to the runway, the pilot of the aircraft observed a Twin Commander performing a go-around due to erratic winds at the approach end of runway 11. The pilot elected to perform a go-around as well. During the subsequent second approach, the pilot became distracted while attempting to maintain a safe distance from the preceding Twin Commander.
As the aircraft transitioned through the landing phase, the wind conditions shifted from a right crosswind to a left crosswind, and finally to a left quartering tailwind. Upon touchdown and during the landing roll, the airplane drifted to the left. The pilot attempted to correct the drift but overcorrected, causing the aircraft to exit the runway to the right and enter a ground loop. The aircraft came to a rest off the runway.
The investigation
The investigation determined that both the left and right main landing gear collapsed during the event, resulting in substantial damage to the aircraft.
