I didn't have to do anything for the written. There is some confusion I think and how people interpret the FARs on the "I can use an expired written to get my ATP as long as I'm employed with a 121/135 company". While I was on furlough I wanted to get my ATP via. Pt. 61, but wasn't sure if I can use it. Some said No, some said Yes including my DPE. I called the FSDO and OKC to get verification, which took about a week, but they all assured me that I was good to go. The key is to get a DPE that knows what he is doing. IACRA will not accept your expired written and will reject it. When I got my ATP we did a paper 8710 and included a copy of my furlough letter.
