This is critical because if you screw up and don’t drill something straight, not only will you ruin the rib, but also the forward spar. What is documented here […]
Horizontal Stabilizer – Skin Drilling

The details for this doubler were provided to me by Mark Frederick and I started with doing some basic […]
