Subject: | Re: Top Fwd Skin |
Matt, I could not help but notice that you riveted the top skin on without
having the windscreen rollbar mounted. I suppose there must be some way
to mount it afterward? And why would you do it that way? Bill

RV-8 List Members,
I've finally come to the place in building where I have to attach the top
forward skin. 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.

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."

>From AC no: 20-27F I quote:
When to Register. 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.

I've gotten some conflicting reports. 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...?
