Default Painted Rivet Removal

I have a small set of leather punches for making holes in leather of various sizes. One of them fits perfectly over painted rivet heads. All it takes is a couple of spins on the rivet head by hand and it will come out clean..........Tom

I totally failed installing the service bulletin.
The rivet heads face aft of the bulkheads on my Aircraft and I was unable to punch out the stems in order to drill the rivets. I tried the lowest rivet because that would be the most difficult one. After one hour of working on that rivet I hurt my back and it took two hours to get myself out of the tail. Got blood all over the baggage compartment.
Iím an A&P and ATP over 6,000 hours and dealing with airplanes along time.
Do not go back in the tailcone without someone knowing youíre there because I didnít think I was gonna be able to get out

My rivets heads also faced backwards. Really not a problem... Don't worry about punching out stems - just drill off the rivet head. I used 90 degree drill motor. Then use plier / side cutter to extract rivet shank.

You think that was fun.... Wait for broken counterweight SB...

Default Removing Pop Rivet Stems

While doing this S/B, I discovered that a Pneumatic Mini Palm Nailer works great for driving out the old stems. Hardest part is fining the right 'bit' to use for driving. I was using the stem from a new rivet that was ground flat.

Default Subtle crack

I did SB-00053 on my 1400 hour RV-12 last weekend. I'd say it wasn't too bad but I wasn't the guy in the tail cone, my buddy was. He didn't complain so it couldn't have been too bad.

We found a nice big obvious crack at F-1208, stop drilled it, put on a doubler, and moved on. The rest looked OK. We buttoned it up, and put on the cover, and finished for the day.

Later that night I got to looking at photos. As I said the crack at F-1208 was obvious. What wasn't obvious was the crack at F-1210, all the way back near the tail. I didn't notice it until I zoomed in on the photo that night. Luckily we haven't put the fuel tank back in yet.

I guess the moral of the story is that some cracks are move obvious than others. Be sure to take a good close look when you do the inspection.
