Is there an ?SB kit? forSB 16-08-01 ? I didn?t see it on Vans site and i was thinking if the stab has to come off might as well get all this done at one time.
Thanks for any help.

I ordered the 18-02-03 kit. See the home page on Vans website for SB details plus click on to order kit ($20 plus shipping).

However, reading the SB 18-02-02 at the end it says to order the 18-02-02 kit which i can?t find on the Vans site.
My RV-12 is 2014 SLSA.

What am I missing?

$10.00 plus shipping. It?s on the website. However I can?t find F-1204M as referred to in Notification January 24 2018.

Just a quick data point....

I removed the stabilator this morning and did the required inspection. Cleaned things up and did a dye penetrant test. No cracks were detected in the spar. I also inspected the AST, no cracks there either. I have 240 hours on the plane, always hangered.

I ordered both part kits (Stabilator and AST) yesterday. Hopefully they will arrive next week and I can start getting the plane back together.

Hoping the bits get to the UK without too much delay. Please...

Having read the instructions I made a list of tools I plan to have to hand:

camera (to take pics)
screwdriver
socket set
tape
wire (eg locking, but string would do)
ruler
sharpie (sharp!)
center punch
primer etc (if you use that)
#30, 40 drill bits and drill
something to deburr holes
countersink tool and bits
rivet squeezer and maybe the wedge
inspection light, magnifying glass (maybe dye penetrant kit)
1/16 punch or old #40 drill bit!
pop riveter
hacksaw/dremel for separating parts
file/grinder for hinge angle prep
superglue for washers

coffee, lunch, hopefully not supper too!

I'll have to remember how to use the various tools. It's been 7 years...

Cheers...Keith

... and maybe a wee dram to celebrate a successful operation?. ;)

A year or so ago I sold a half share in my RV12 to a flying partner. I asked him whether he wanted to buy the front half or the back half. He elected to take the back half. Result!!! I'll have the dram now ;-)

I saw the feedback from the related AST mod. I, too, am happy that a potential problem has been spotted and a fix made available. $30 for both fixes and maybe two days effort to implement. And a few more bucks for consumables and couple more days to do an annual inspection. A very reasonable outlay of cash and labour for a year of flying.

Cheers...Keith

My RV 12 is here at Marco Island from Marysville, Ohio for the month and I find myself grounded by these SB, especially the stabilator spar issue. Fortunately, a very kind and experience A & P is ready to assist in doing the inspection once the kits (in case cracks are found) and my build book arrive. The text of the SB 18-02-02 is lacking in clarity (at least for me) but the folks at Van?s build assist confirmed my reading that step one is removal of the stabilator and conducting an inspection (my folks here at Marco can do a magnaflux) and if no cracks are found re-install the stabilator and then do the kit at next annual/100 hrs. Since my shop in Delaware Ohio is well versed in the RV 12 if all is well I?ll have them do it there. My aircraft, first flown the end of 2013 now has 200 hours and has always been hangared. So I am hoping for the best. Was the inspection fairly easy to perform once the stabilator was removed? Thank you for any input, words of encouragement.

ExErcoupeGuy,

Yes, the inspection itself is fairly easy to do. Once the stabilator is off the airplane, remove the the hinge brackets located on the front side of the stabilator spar. The service bulletin has good pictures of what to look for in that area, however, you will probably have to remove paint in the area with some fine sandpaper before you can really make a thorough inspection. Hope you don?t find any cracks so you can get your plane back home in a timely manner.

It take it that your airplane is a S-LSA, not an E-LSA?
