Circumstances:
After several touch and go circuits, the pilot noticed the right landing gear was broken and swinging free. A landing was made directly into wind on the remaining wheel but on touchdown the aircraft swerved to the right before coming to rest on its nose, breaking the propeller, and damaging the right wing. The pilot said the landing gear had suffered a fatigue failure at the upper weld area adjacent to the rubber bungee attachment and this was a known problem on the aircraft type. The manufacturer subsequently issued a service bulletin to install additional landing gear restraint cables to preclude fatigue failures of this type.
