Checked alignment and level of right aft wheel fairing; all good. Used magnets to lay out and drill pilot holes in right forward fairing for U-807-R bracket. Layout nominal, but discovered that a fiberglass pad will need to be added to faring to fill gap between bracket and fairing. Lessons learned from notching right fairing parts will be applied to make left wheel fairing notches more accurate. Intersection fairings will be installed later and will hide notch flaws.
