09-13 Match drilling trim tab spar to trim tab hinge - hole size???

Hey builders,

I'm about to match drill my trim tab spar (E-01405) to the trim tab hinge (page 09-13).
The instructions say to use a #40 drill. But my trim tab spar is prepunched with #30 holes.
So somewhere is a mistake. Are the instructions wrong and should I use a #30 drill for the aft side of the trim tab hinge (for the forward side I have used #40 and everything was fine)? Or is my E-01405 trim tab spar pre-punched with the wrong hole sizes?

Does it matter if I use #30 or #40 holes on the trim tab hinge?

Thanks a lot!

Best,
Malte
 
There was an identical question on the RV-14 Facebook page. Sounds like Vans either changed the plans (less likely) or mis-punched a batch of parts (it happens).

I'd email or call support at Vans - I would guess that you'd be fine to match drill the hinge for -4 but not sure if edge distance is right.
 
I had an issue where Van's sent me two left aft wing spars. I spent 30 mins trying to figure it out until I posted pics on here. Van's was great in sending me a new piece!
