Started to work on my RV-14A rudder recently and while final drilling the rudder horn (R-405PD) to bottom rib/spar assembly, I noticed my holes were slightly elongated (between 0.010" to 0.020"). Not sure how this happened, but I know this is out of spec for AN470AD4 rivets (0.125"-0.135" hole size). Anyone know if this is still OK or if it's possible to drill these out to AN470AD5 rivets? Or should I just scrap these and do them over? I have sent an email to Van's as well, so hoping to hear back from them soon.
