Default SB kit packing list

My SB kit arrived recently, but I can't find a packing list to check that everything is there. One of the brown paper bags has a large hole in the corner - a small plastic bushing fell out as I took the bag out of the box.
Can anyone scan and email me the packing list please? PM me for email address.

Thanks

Todehnal,

I can't believe I forgot about the drill speed affecting the chromalloy cutting. I reset the drill speed today and had no problem with he countersink. Thanks.

Rich

Thanks - I missed that. I was expecting to find a packing list similar to the subkits. That's what you get for rushing and not leaving enough time to do a job properly!
I'll be back home again and making a start on the SB work next month.

Default Cracks in Center Section & Outside Gear attachment Holes

Hi Guys

I wanted to get some opinions from you guys.
We have just done the SB-12-11-09 and found cracks in our center section holes for the outside gear attachment bolts.

The right side has some small cracks but our left hand side aft bolt hole has some MAJOR cracks and underneath the hole it looks like a tear with some of the aluminum HIGHER on the left hand side of the crack than the right of the crack.

Vans suggests stop drilling the cracks as per SB and also they suggest an ADDITIONAL doubler plate over the aft hole on both sides.
VANS assures us that this will prevent any further damaged but my partners and i are also concerned with cracks we might not be able to see.

These crack are of huge concern to us especially in such a structurally important part. In one of the pics you can see a crack even running with the grain of the center section.

I know VANS knows best but what do you guys think, any input will be appreciated.

If Vans has seen the pictures, I would follow the recommendations of the engineers.

Default thanks

thanks Geico266

We even considered what the implications were of replacing the entire centre section but we don't even know if thats possible on an existing airframe and if we might do more harm than good.

I guess VANS won't let us fly if they didn't consider their fix safe.

VANS engineers recommended an additional doubler that fits over the TOP of the aft bolt hole to give us spacing from the existing cracks.

I agree that Vans' solution is probably the most technically sound since they know the product best. How many hours and under what operating conditions did it take to form the cracks? If they have slow growth rate You should be able to monitor them and determine if the fix is effective. If they stop growing you're OK. I can't speak for Vans but I doubt they would suggest a fix if they weren't confident it would work.

Having reinstalled the gear twice, my advice would be to temporarily install the big inner centre bolt from the bottom without installing the intervening plates at this stage. It's easy to get this through the leg and the central channel, then put a couple of turns on the nut from the top to stop it dropping out again. This secures the leg in the right horizontal position, before you try to get the outside bolts in. And this can be facilitated by lining up the holes from the top with a screwdriver smaller than the hole diameter. Finally remove the big bolt and reinstall from the top, with the various additional plates in place.

Cheers...Keith

Thanks Keith

Our top doubler plates are on their way - we still need to stop drill the cracks and send the pics to VANS which i will do shortly. will post some pics of the fix so other members can check it out.
