4. Wing to Fuselage Attachment
___________________________
A. A connection exists between the wing and the fuselage by means of six flanged chords running between the bulkheads at stations 540 and 664, and at buttock line 70.85 along the upper edges of the wing. Refer to figure
2.
B. The bulkhead at body station 540 and the center wing box front spar are integrated into one piece, and the bulkhead at body station 664, and the center wing box rear spar are also integrated into one piece.
C. A connection exists between the lower surface of the center wing box and the fuselage keel beam which passes beneath it.
D. Other points of attachment between the fuselage and the wing include the main landing gear support beams, the longitudinal floor beams, and the wing to body fairings. The wing to body fairings are attached to the fuselage and to the left and right wing upper surfaces.
5. Empennage
_________
A. The empennage comprises a dorsal fin, a vertical fin, an adjustable horizontal stabilizer, rudder and elevators.
B. Left and right horizontal stabilizers are removable from the adjustable center section truss located within the fuselage. This center section is movable, pivoting on two hinge joints attached to a bulkhead in the fuselage. Each stabilizer consists of two spars with interconnecting ribs and skin. The leading edge is removable.
C. The elevators are graphite skin covered, spar and rib structures, containing balance panels, and elevator control tab.
D. The vertical fin is composed of front and rear spars, interconnecting ribs and skin. The leading edge is removable. The fin and rudder may be removed.
E. The rudder is a graphite skin covered, spar and rib structure.

REDUCED VERTICAL SEPARATION MINIMUM (RVSM) - INSPECTION/CHECK
_____________________________________________________________
1. General_______
A. RVSM will permit the airplane to be separated by 1000 feet vertically from FL290 to FL410, instead of the current 2000 feet. RVSM makes more available route assignments and gives benefits to operators through better route assignments and reduced schedule delays.
B. This procedure contains two tasks. One task is to visually examine the airplane skin for smoothness in the area of the pitot-static ports. The second task is to measure the skin waviness in the area of the pitot-static ports.
