_____________________ The spoiler is a wedge-shaped structure. It has carbon fiber top and bottom skins, sides and trailing edge profile, bonded to a honeycomb core. There are four machined aluminum-alloy attachment-fittings. These are the inboard and outboard hinge brackets (with links) the center hinge and the spoiler actuator attachment-fitting. The actuator attachment-fitting installed with the center hinge. The spoiler is attached by the links and the center hinge to the mid rear spar.
A titanium alloy rubbing strip on the trailing edge of the spoiler prevents damage to the spoiler when the flaps are retracted. Seals are installed at the inboard and outboard ends and along the leading edge of the spoiler.
