Final-Drill #19 the four nutplate screw holes in the U-1010-L Main Wheel Fairing Bracket. Final-Drill #40, countersink and deburr the nutplate attach holes and attach the hardware as per the callouts.
Cleco together the U-10S7A-L Wheel Fairing Front and U-10S7B-L Wheel Fairing Rear. Final-Drill #19 the two fairing to bracket attach holes in the wheel fairing front andwheel fairing rear. Countersink these holes to accept AN507C832RB. Final-Drill #28 three (of the seven) evenly spaced #40 screw attach holes. Disassemble and deburr. Install three K1000-06 nutplates at these #28 holes. Final-Drill #40 and countersink for nutplate rivets. Deburr Ihe holes. Rivet the nutplates to the wheel fairing rear as per the callouts.
Reassemble the fairing halves using three #6 screws and clecos at the rest of the holes. Final-Drill #28 the remainder of the #40 holes. Disassemble the fairing halves. Install the remain ing nulplales. Reassemble using #6 screws. Countersink the #28 holes in the U-1057 A-L Wheel Fairing Front.
48-10, Step 1
The gear leg fairing must be aligned with no load on the wheels simulating the in-flight condition of the gear legs. The following steps require the aircraft to be supported by jacks far enough off the ground that the wheels no longer touch. Level the aircraft at the F-1015C-L/R Mid Cabin Decks.
Slip the U-1017-L Gear Leg Fairing over the gear legs and brake lines and insert the hinge pin from the bottom. The hinge pin is thin enough to curve during insertion without taking excessive permanent bend. Roughly align the gear leg fairing to the airflow and the notched centerline marks with the gear leg centerline. Clamp the gear leg fairing to the gear leg to temporarily hold it in place.
The alignment of the fairings is important and can significantly affect the way the airplane flies. While a very careful "eyeball" alignment job might come close this is made difficult because of the sweep back of the gear legs.
