Incident Details
An ATP-rated second pilot was undergoing a checkout for commercial operations in a ski-equipped aircraft, supervised by a company-designated instructor who had previously landed at a remote snow-covered site. The second pilot conducted a takeoff, entered the traffic pattern, and initiated his first ski landing.
Sequence of Events
During the landing, the aircraft bounced twice on the rough snow surface. Following the second bounce, the right wing dropped, causing the right ski to drag along the surface. The right main landing gear subsequently collapsed at the gear box.
Examination
Post-incident examination confirmed that the right main landing gear had failed at the gear box structure. No further details about the aircraft or occupants were provided in the source.
