The RV-14 was designed to not require final drilling, but, in the interest of reducing costs, a few parts from other kits are used in some instances.
Because these parts from other kits do not have holes punched final size, those holes require final drilling. For the most part this is only ribs in the empenage and the wings. Pretty much everything else in the RV-14 kit is prepuched.
The attempt was made to detail all of these instances in the construction manual, but it is always possible some were missed. Using a rivet to check the hole size is a good cross check.
