We were away for the weekend, so I didn’t make any progress over the last few days. Last week I had a call from Rian at Vans asking if I had observed any corrosion in my QB kit. I told him about some I had seen on the wing rib flanges and webs, and that I was planning to sand and repair. This wasn’t symptomatic of the problem Rian was tracking down, but he recommended scotchbrite and prime the affected areas. Tonight I fixed the issue; scotchbrite on all affected areas, then spray-can self-etching primer to seal it up. I papered over all the wiring, bolts, and electronics, then carefully painted the impacted areas. There were several ribs on both wings that needed treating. I also inspected the other areas inside the wings to check for signs of corrosion but couldn’t find anything.
