United Nations aircraft age limitations?

[capnflyright]

I'm searching throughout the net trying to find out if the UN has aircraft age limitations. If you happen to know or know of the proper area to find this out (before I pull all of my hair out) I would really appreciate the help. Thank you.

I'm not aware of any limitations. I got called for a position doing UN flights in a LR35 recently, in the Darfur area (which I turned down due to the schedule). I'm not a kid.

Are you asking about maximum age with respect to 60 yrs old? Or other lower limits similiar to typical military restrictions?
