Began fitting LH wing tip. Installed aileron and used as guide to match to wingtip. Trimmed LH wing tip as required for proper fit and clearance from aileron. Match drilled wingtip to wing skin for screw attach holes. Removed tip and deburred wing skin and tip. Drilled and countersunk nutplate attach holes in wing tip then installed nutplates. Countersunk wingtip nutplate holes for #6 dimples. Dimpled wing skin for #6 screws. Fitted and drilled tip rib as shown on plans.
