I Learned About Flying From That (ILAFFT)

[Brilliant Stuff]

I was given to understand the reason why fuel caps are no longer tehtered is because the thinking is that the cap will roll of the airframe when you start the helicopter or lift into the hover instead of hanging on for dear life until the chain fails and then goes into the tail rotor. That's what happened to me on the R22.

I stand to be corrected.

Thanks helinut.
