 3.  Outboard Flight Spoiler Structure (Fig. 1)
_________________________________
 A.  The outboard flight spoilers, No. 1 thru 4 and No. 9 thru 12, are of similar construction to that of the inboard flight spoilers except for the center (hinge and control package) fitting. The point of attachment for the control package is aft of the hinge centerline and in a cavity in the honeycomb. A rectangular box structure strengthens the spoiler in this area and is composed of the front spar portion of the center fitting, two side supports (spliced angles), and the aft support (channel). All are part of the bonded assembly.
