Had the Beaver over at the shop today for an 'annual'. Mechanic broke one of the black plastic hinges on the roof ladder. He had to swing the ladder up out of the way to access the engine bay and when so doing, broke one of the hinges. Looks like 15 years of sun and fun had pretty well weakened the plastic, but, anyone have a source for these ladder parts? Hinge fits over the al tubing and two screws hold each end of the hinge tight to the tubing.
