Angier,
I’ve been through this recently with my airplane and have learned the following:
1.The placard has to be fireproof and “permanent”. No aluminum or plastic. Should be made of steel.
2.The line items and way of expressing them on the placard are specific – I don’t recall all of them, but many placards are not completely correct. Your DAR may require you to change it if the data is not exactly accurate.
3. Tape is not legally acceptable and you may lose the thing in flight if you try it. I suggest using Hysol adhesive. Sand the fuselage and the back of the placard with 80 to 150 grit, clean with acetone and bond into place with a thin layer of adhesive. Make sure it’s completely wetted out and you need to have it under pressure against the fuselage during the initial set time.
Hope this helps,
By the way, one dilemma to solve for yourself is whether to attach the plate prior to paint of after. Either one requires compromise.

Subject: [LML] Re: Data Plate Attachment
I'm looking for a solution to permanently attach my data plate to the airframe. The surface will have paint and clear coat which means an area the size of the plate will need to be scuffed up in order for adhesive to bond correctly. Have others done it this way? How about a very thin (5mils) or so double sided adhesive tape? Rivets are really not an option.
Suggestions...
