I have a corrosion issue which is a bit surprising in an aircraft with 470 hours that first flew in 2014. It is limited to a few specific places.
Worst area is the RH flaperon with patches of corrosion the full length, all located on the upper surface just behind the lap joint. LH is similar but not as extensive. Both outboard, rear upper surface wing skins have a patch also, again just behind the lap joint. There is also a small patch on the turtle deck near the front lap joint but not as close as on the other areas.
There is no bulging of the joints. Doesn't seem to have extended beyond the areas that are obvious. Noticed the first patch a few months ago - the others have appeared fairly rapidly in recent times..
The aircraft has always been hangared and is well away from the coast. It was the builder's third RV, so expect he would have taken care of the kit during assembly.
I have a paint shop lined up to fix it. Has anybody else experienced similar? I am wondering why it has appeared in these limited places (nothing anywhere else), and whether there might have been localised defects in the aluminium sheet.
