Talon Universal joint failure

[Homer Bell]

I suspect many of those failures were the wrong belts. I’ve seen many ships that when you look , had aftermarket belts. People will say “oh I got those local, they are direct replacements “ . No they aren’t. Another thing is they will stick the tailrotor in the ground or the hangar door or whatever, change the tail rotor and not the belts. That will almost guarantee a failure a little later.
I did that exact thing myself 50 years ago. I had people that I respected told me I should sue the belt manufacturer. That attitude has killed the aviation industry, and many other businesses. I no longer have gathering like I had years ago pretty much because of liability fears.
