Saw a helicopter over the week end with the following registration.

5N-RAA

When I tried to look this up in the FAA data base is states that you
can not register aircraft with more than 2 alpha characters.

If so, could this be some sort of government aircraft. I do seem to
rememebr seeing some sort of small decal referring to the "government"

It's not a US (FAA) registration.

I did a Google on "aircraft registration 5N" and it appears that your
helicopter is from Nigeria.
