Oil Canning
I know this subject has been discussed many times and for the most part I have had it in control to a acceptable point.
I finished my wing tanks and finely closed up my skins on the top of the wings a few weeks ago.
The W-1204B Skins at the outboard end of the wings have Oil Canning that has caused me not to get a good night sleep since then.
This area is 13.75" by 23.1" and is a simple span design ( one side at the end of the wing and the opposite on the last outboard wing rib ) and should provide about 22.93 lbs of lift.
It is also the largest and most flat area on the top of the wing.
The span on the wing ribs is only about 11.6" ( 2.15" less than the W-1204B span ).
I went out to the shop today and removed the W-1204B skins and will order two new ones from Vans on Monday.
Has anyone had the same problem with this or maybe the dimpling of my skins in the problem.
I will make a stiffener out of the top 1.5" of two new wing ribs.
Any Suggestions are welcome
