There are five spoilers on the upper surface of the wing trailing edge. Spoiler 1 is connected to the rear false spar, inboard of the kink position. Spoilers 2 thru 5 are connected to the middle and outer sections of the rear spar, outboard of the kink position.
The spoilers are extended or retracted for these functions:
-roll function
-speedbrake function
-ground spoilers function.
The drive mechanism of the spoilers is electrically controlled (Ref. 27-90-00) and uses hydraulic power to extend or retract the spoiler surfaces (Ref. 27-64-00).
2. Component Description
_____________________ The spoilers are wedge-shaped structures. They have carbon-fibre top and bottom skins, sides and a trailing edge profile, bonded to a honeycomb core. They are connected by aluminum-alloy attachment fittings and hinges to the rear spar and rear false spar.

The spoiler 1 is installed on the fixed structure of the trailing edge. It is connected to the rear false spar, inboard of the kink position.
The spoiler 1 is one of five spoilers which are extended or retracted for these functions:
-roll function
-speedbrake function
-ground spoilers function.
The drive mechanism of the spoilers is electrically controlled (Ref. 27-90-00) and uses hydraulic power to extend or retract the surfaces (Ref. 27-64-00).
2. Component Description
_____________________ The spoiler is a wedge-shaped structure. It has carbon fiber top and bottom skins, sides and a trailing edge profile, bonded to a honeycomb core. There are four machined aluminum-alloy attachment-fittings. These are the inboard, outboard and center hinges and the spoiler actuator attachment-fitting. The actuator attachment-fitting is installed within the center hinge. The spoiler is connected to the rear false spar by the hinges.
A titanium alloy rubbing strip, attached to the trailing edge of the spoiler, prevents damage to the spoiler when the inboard flap is retracted. Seals are installed at the inboard and outboard ends and along the leading edge of the spoiler.
