...a bit confusing flydog...the 8410 is not a record of training but rather a record of the result of a checkride...none the less I get the idea....
Everyone is shooting in the right direction. However, I'd like to give my two cents. The 8410 is submitted to your POI, it is entered in the FAA computer database. OKC DOES NOT GET A COPY OF THE 8410 and IT IS NOT available in a request for your Airman File. It is operationally correct for the POI to file the "hard copy" until your next checkride. After the next ride, the older 8410 makes it to the trash.
So, one copy goes to your POI, one to you (which you are not 'required' to have in your possesion to operate), and one to the Operator. If you lost yours, go to the company. If they lost thiers, or you don't want to ask them (for whatever reason),....call the POI.
Ya' know....they're there to help......
...and Simon...right comment...but, wrong form....
