Drilling the fuselage holes:
Using a self-centering 11mm drill piece, redrill all of the upper cowl fuselage holes.
Add a chamfer and check under the hole to see if the surface is flat. The surface needs to
be flat for the quick connect fitting. If necessary, grind the surface flat.
Mount the quick connect fittings and tighten with a spacer and nut. Apply Loctite 243.
Note: The quick connect fitting located at the top of the cowling in the center must be
connected using epoxy mixed with cotton, because there isn't enough space for the
spacer and nut.
Now redrill the fuselage holes for the bottom cowl using a 7mm self-centering drill piece.
