Brief Description: Drilling for Rear Spar Fastener
Finally, time to locate and drill the pilot hole for the rear spar fasteners. Re-checked the wing sweep, incidence angle and wing tip to VS distance, carefully measured to ensure I have the minimum 5/8" ED, and marked the location. Using a new #40, carefully enlarged the mark manually twisting the bit. Then, final drilled the pilot hole through the rear spar and rear spar tabs.
