Temporary Expiring
Sorry for digging up an old thread, but I thought my experience could help someone with this same question. I had some of my paperwork lost for my ATP and I had to get a new temporary not once but twice. My case was different because my paperwork had not been processed and, and as a result they couldn't issue me the 60 day letter. Both times I simply walked into my local FSDO and asked for help with my temporary. In both cases I explained the situation to the inspector. They went back to research the situation, I assume the probably called my POI and/or APD to verify my story, and then issued me a new temporary on the spot. No big deal.
Every time I go to the FSDO they've actually been quite helpful. It's not the scary place some people make it out to be.
