The Plan # is the serial number starting from day one when the plans were put on the market. That is also your proof number if the FAA wants to check back with RR that you have a legal set of plans. You are authorized to build one KR using that set of plans and no more than one. It's in the copy write laws and it is FAA policy to enforce this. If your FSDO checks on this, may be another matter. The Book Number is the update version. So, if you have a Book No. 82, that is the revision 82 edition. I got this info from personal conversation with Jeannette Rand.

Does anyone >have the correct meaning of the top number. This is only an educated guess, but it is my understanding that RR keeps the name and address of the original plans purchaser (and possibly any known secondary) in notebooks in numerical sequence. Since they are over 10K on the KR-2 / 2S that makes for a lot of books. My basic KR-2 S/N is 9707, "Master File Book No.82". Allen G.
