Hi All,
Maybe this is one of those things that isn't terribly obvious, but -
having used a variety of screw type clamps - I'm wondering why
plain old spring clamps aren't suitable for this application. I can't
ever remember having one fail in service. (photos below)
They're not expensive or exotic enough. If it goes on an airplane, by golly, it can't be cheap or straight forward.</sarcasm>
Thanks for busting the myth, Al. I'd like to add one more piece of supporting data. Any nipple or tube that the hose is connected to should have a bead rolled on it. That's going to create an comparitively *HUGE* obstruction that the hose with the associated clamp will have to slip over. If your bead isn't large enough to make a good seal on the inside of the hose, and then the clamp is loose enough to slip over both, I'd expect that you'd also have the engine strapped to the plane with safety wire (with TWO wraps of wire, just to be safe).
