Cracked ribs at the main spar

Post by 4945 »

I have a set of wings with a couple of cracked ribs where they attach to the main spar. Cessna made a reinforcement for it. Does anyone have info on that?

I should have specified - they're 140 wings.

I'm trying to help you out. Somewhere I have a drawing for a wing showing the factory doublers and the p/n's for them. I moved 3 years ago and can't find that one piece of 120/140 tech lore.............still looking. I contacted the previous 120/140 tech adviser Bill R. out of Minnesota to see if he has a print.
