Incident Overview
A flight instructor was demonstrating a short approach and touch-and-go landing to a student pilot in a complex airplane. During the final approach, the instructor was unable to correct for a quartering tailwind, resulting in the airplane touching down sideways on the left main landing gear. The instructor later remarked that the landing "felt a bit unusual, but the approach had been stable and the landing wasn't that bad."
Post-Landing Events
After the initial landing, the airplane took off, but the landing gear would not retract. The instructor troubleshooted the problem and declared an emergency. Subsequently, the instructor landed the airplane with an unsafe landing gear indication. Upon touchdown, the left main landing gear collapsed, causing the instructor to lose directional control. The airplane then impacted taxiway lights and came to rest upright adjacent to the runway.
Damage and Examination
Postaccident examination revealed substantial damage to the left wing. Further inspection of the left main landing gear and wing showed overload damage to the landing gear wing attachment. The flight instructor stated that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
