There seems to be a lot of confusion and different interpretations of the Regs. regarding the ATP written. I took my ATP checkride in April and was able to use my expired written...

I took my ATP Written in March 2007, and I was furloughed Comair January 2009. My written expired on March 2009. I wanted to take my ATP checkride Part 61 in April, but I was unsure if I could use my now expired written exam. The DPE told me I was good to go, since I am still "working" at my airline. However, I called up my local FSDO to confirm. The FSDO had to call Oklahoma City to confirm as well. It took about a week to get an answer and clarification, but they all assured me I was good to go.

My DPE knew how to handle this situation, as he had dealt with it before. We just did a paper 8710, because IACRA would just reject your written and say it is expired. We also attached a copy of my furlough letter to proof that I still had a seniority number and was on "furlough status". It's was a bit of a pain in the butt, but it is worth it if you can figure it out and have a DPE that knows what he is doing.
