Cessna C337 SID

[Skymaster337B]

Watch the video on YouTube. I always check what it said to check without an SID. I wish that Cessna would just admit to a service life for its old airplanes. How long can a C-172 wing last, forever? Or is there an hour limit to its life? Cessna knows the answer to this question, but for some reason won't tell us. The same is true for the 337 too, the only difference is that Skymasters are built more beefer.
