I suppose there must be some way to mount it afterward? And why would you do it that way?

A lot of the rivet locations are about impossibe to get to - especially along the sides in the gear boxes. I've considered cherry max rivets, but the smallest size is too large. Is anyone aware of screw s being used instead of rivets for this skin? If the longerons are tapped and platenuts are installed on tops of the bul khead, firewall and panel, flat head screws (NAS514 machine screws) could be used. Also, this would make it possible to remove the skin and windsh ield, I believe. Any comments would be appreciated. Breece Nesbitt RV-8 N28117 Hi Breece, The text below is from my log entry regarding this vary thing. "CherryMax CR3214 Pop Rivets On Gear Towers There were about 6 rivets on each side of the top instrument panel skin th at were located inside the gear towers. Consequently, getting to the backs ide to buck them was nearly impossible. I suppose with just the right buck ing bar, crafted specifically just for reaching those pesky rivets, you pr obably could buck them, but of the 8 or 9 bucking bars I have, nothing cam e even close. I did a little research on the Net and found that many people have been us ing CherryMax CR3214 4-4 Pop rivets for these few rivets. These, however, seem to be a little hard to find because they have a 1/8" body, but a 3/3 2" countersunk rivet head. I found a great source for them, however, at Ge nuine Aircraft Hardware Company ( http://www.gen-aircraft-hardware.com/sto re.asp?alternate=CR3214%2D4%2D4 ). These guys have all kind of nifty har dware for aircraft and are very friendly and helpful on the phone. Give th em a call and have them ship you a catalog; a resource guide in and of its elf. I ordered 30 or so of the CR3214 4-4 and when they arrived, I drilled the holes out to 1/8" and then stuck them in the holes. The are really cool and leave a completely flush rivet that almost cannot be distinguished fr om a standard 426 3/32" rivet. In fact, the mandrel of these pop rivets br eaks off exactly flush as well, so they don't even leave any ugly hole. By the way, if you have a decent "standard" pop rivet tool, it should work with the CR3214 rivets as well. No need to buy a special rivet tool."

We recommend you apply for registration 60 to 120 days be fore you finish constructing your aircraft and before you submit FAA Form 8 130-6 to us. This should allow you to get your registration information in time for your FAA inspection. AC 20-27F is pretty much step by step walk you through it. My copy came in the package sent to me by my FAA FSDO. Regards Vince H.

Do you have your final registration cert from the FAA in hand before you can apply for your Airworthiness cert=2C or is the pink copy of the registration sufficient? Matt Dralle I found the following bit of information on the FAA web site regarding registrations and the use of the Pink copy. Here's an excerpt from the link that follows: "You can also check the Document Index to see if recently mailed registration documents have arrived at the Aircraft Registration Branch. Arrival of registration documents in the Registry enables confirmation that application for registration has been made and temporary (pink-copy) operating authority is in effect. Processing registration documents related to a change in aircraft ownership averages 16 working days after their receipt." http://www.faa.gov/licenses_certificates/aircraft_certification/aircraft_re gistry/registration_status/ To me=2C this sounds like as soon as the FAA has received the registration and entered it into the system as indicated by an on line status search=2C you are allowed to use the Pink copy until the real copy arrives. I would then assume that Airworthiness could be applied for under the same conditions...?
