Looking for Flap Cables

For what it's worth, the reason I made my comment is because I've changed flap cables myself, I'm an AME here in Canada,. On one Skymaster, visually inspecting the cables before they were removed showed nothing. Once removed one cable had around 40-50% of the cable strands broken. There was no way of seeing this. With half the cable strands broken I question how much strength is left in the rest of the cable.
