A few days ago Van's came out with Service Bulletin SB 16-03-28, which recommended a mandatory inspection of where the rear spar met up with the inboard aileron bracket. Full details can be obtained from the Van's Aircraft Website: http://www.vansaircraft.com/pdf/sb16-03-28.pdf.
The first step in the inspection process is to remove the outboard most inspection panel under the wing.
The SB recommended using a digital camera to take a picture of the area to be inspected, and then to use the zoom function of the camera to inspect for cracks.
The right side looks clean.
Onto the other side.
Good news - the left side looks to be in good shape also. No noticeable cracks. The SB indicated this area must be inspected during the annual inspection.
Ugh, the surface corrosion under the wing has been getting worse. This is part of the reason I have been investing into some polishing equipment.
I decided to give the inspection panels a go at polishing. I started off with Nuvite Grade F7 polish.
I dabbed just a little bit of the polish on the panel. I manually applied the polish with just a microfiber cloth.
The results after the polish. It did a significant job.
The next step is the Grade C polish.
A few dabs of this as well.
The shine is starting to come through.
I finished it up with some Purple Metal Polish.
Wow! The end result is mirror quality!
Comparing the two sides is night and day!
My polish addiction has gotten worse over the past few weeks. I found a nice deal on a Cyclo polisher.
I have the Cyclo polisher a spin on the rudder. Although it is difficult to see in this picture, it did an amazing job polishing the rudder. The thing has more-or-less a mirror finish with just a little work using the Purple Polish.
I still have a lot of airplane remaining, but I am thrilled with the results. My discolored hands show proudly my polishing badge of honor! Looking forward to setting aside more time to get the rest of the RV looking sharp.
