If one wanted to reserve a unique N-number while they were building a plane,
how long can you keep renewing the reservation (understanding you'd have to
pay a fee each time)?

I thought it was for only a year or so, but faa.gov makes it sound like you
can renew at least once, but didn't see an upper limit on the number of
times.


You can keep renewing it as long as you keep sending them the fee.

I finally stopped renewing N1RN and some glider out in Ohio grabbed it.
