Background: Transport Canada received two reports of fractures of the main landing gear side- brace fitting shafts on CL-604 aircraft. The fractures were caused by corrosion on the forward side of the side-brace fitting shafts. Although the fractured shafts did not become dislodged in either of the cases reported, breakage of a shaft could potentially result in collapse of a landing gear.
