Why do you need a new instrument rating if you already passed your checkride?

But for checkride purposes, any written exam has to have to embossed seal on it. Unless the examiner uses IACRA and even then I would still make sure to have the written just in case something gets screwed up.

You will have to call up Oklahoma City and talk to the nice lady Jo who is in charge of replacing lost Airmen written exams. They have your exam on file from when you took it at CATS or Lasergrade testing center, and they will print it out again and stamp it. You will have to send out there a FedEx or UPS envelope with paid return shipping. The processing fee is $2 also.
