Pinedale, WY, USA
N117CE
Glasair Aviation LLC Sportsman
The pilot was demonstrating landing the tailwheel-equipped airplane on a mowed grass field, which sloped from left to right. The main wheels touched the ground without incident but, as the tail dropped the airplane veered sharply to the left. The pilot applied right brake and full right rudder in an attempt to control the airplane, yet it continued to swerve until it was 90 degrees relative to the direction of travel. The right main landing gear subsequently separated and the right wing and stabilizer contacted the ground. The airplane sustained substantial damaged to the fuselage, stabilizer, and right aileron. The pilot reported no preimpact mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation.
