Drill the U-10S7B-L Wheel Fairing Rear as per the callout at the intersection of the U-1004B Nut Extension and the molded step. Mark the hole location for drilling from the inside. Pull the fairing forward and drill with a right angle drill from the inside out, or translate the hole location to the outside surface and drill.
Cleco the U-1057A-L Wheel Fairing Front to the U-10578-L Wheel Fairing Rear. Insert a 1/4 bolt through the fairing and screw it into the U-1 0048 Nut Extension without tightening it down. Carefully adjust the wheel fairing position until it is aligned with the aircraft centerline. To accomplish this drop plumb bobs from the fore and aft center of the fuselage and snap a chalk line through these marks, transferring the aircraft centerline to the floor. Measure from this centerline to the points depicted. When all the measurements are equal the fairings are parallel to the aircraft centerline.
Shim between the fairings and the tire to keep the fairing from moving while drilling. Working from the inboard side of the U-1057A Wheel Fairing Front and U-10578 Wheel Fairing Rear sight through the translucent fairing and locate the ~sharpie" pen marks. Drill the fairings and bracket at the four nutplate locations. Remove the wheel fairings. Roughen the inside of the wheel fairings aggressively at the #36 holes. Reinforce an area about 3" in diameter around each hole with one or two layers of fiberglass. When cured drill up to #27 the four #36 holes in the fairings.
Tap the U-1010-L Main Wheel Fairing Bracket for 6-32 screws. This will allow the temporary mounting of the fairings to the bracket (for final alignment) with 6-32 screws rather than clecoing to the bracket which tends to flallen the fairing at that location. Reattach the wheel fair ings to the main wheel fairing.
