- Definição1
- A plate, series of plates, comb, tube, bar, or other device that projects into the airstream about a body to break up or spoil the smoothness of the flow, especially such a device that projects from the upper surface of an airfoil, giving an increased drag and a decreased lift. Spoilers are normally movable and consist of two basic types: the flap spoiler, which is hinged along one edge and lies flush with the airfoil or body when not in use, and the retractable spoiler, which retracts edgewise into the body. In some cases, spoilers are linked to the ailerons and work in unison with the ailerons for improved lateral control at low speeds. In some aircraft, they have replaced ailerons. The spoilers are used as airbrakes, lift dampers, and a means of lateral control.

- Contexto
- The investigation discovered that during maintenance to replace the right outboard flap, the right wing spoilers had been placed in maintenance mode (so as to move freely) and moved using an incomplete procedure; specifically the collars and flags were not fitted. The purpose of the collars and the way in which the spoilers functioned were not fully understood by the engineers.

On the figure, the airplane's right wing spoiler is deployed, while the left wing spoiler is stored flat against the wing surface (as viewed from the rear of the airplane).
