Aircraft
Enroute to KOSH. Near waypoint (RIPON) extremely heavy air traffic. Advised by AirVenture Controller to break out to the west and fly holding pattern. Again encountered heavy traffic while holding. Decided to divert to Y50 to land and wait for better traffic conditions. Y50 AWOS reported 8 knot crosswind with some gusting for Runway 31-13. Flew direct to Y50; made crosswind entry to left traffic for Runway 31. At round out for landing sensed increasing sink rate. Applied full power to slow sink rate but experienced hard landing. At touchdown; the right main wheel assembly departed the aircraft. Aircraft veered to the right off the runway into soft ground and stopped. Two passengers and the pilot exited the aircraft through the right and left doors. No one was injured. In light of the high traffic and hot and humid weather conditions; flying a longer downwind leg would have given me more time to adjust to flight conditions and make a better landing. On inspecting the right main gear assembly; two days post event; there were signs of corrosion and what appeared to be fatigue fractures at the end of the gear strut. I believe the hard landing probably precipitated an already impending failure.
C182 pilot reported the right main landing gear assembly failed on landing.
