Bowed engine mount

Post by 8037 »

1946 140, Continental 85 HP. Landing incident put plane on its nose. The engine mount has two bowed tubes, bowed not bent. Anyone taken a bow out of a tube, and how did you do it?

There's no distinction between a bow or a bend. They are permanently deformed. If it's not straight it needs to be replaced. To do that you really need a jig. Wag Aero used to do them, but I don't know if that part of the business is still in operation.

I agree, you need to take a close look at the stringers behind each of the mounting points on the firewall. Are there any wrinkles in the boot cowl?
