Malaysia's Transport Minister Liow Tiong Lai said tests in France had made this link with a recentlydiscovered flaperon from an airplane wing.
He tweeted: "The flaperon is offi-cially identified as being part of a Boeing 777.
Aviation experts who have seen widely circulated pictures of the debris said it may be a moving wing surface known as a flaperon, situated close to the fuselage.
It is almost certain that the flaperon is from a Boeing 777 aircraft.
is an aerodynamic surface that increases the wing's lift during takeoff and landing - like a traditional flap - and also is used as an aileron for roll control.
The WTE activity, which encompasses wing flaps, flaperons
, ailerons and airbrakes, is taking place at GKN Aerospace s Filton, UK operation whilst the LPT case is manufactured at the company s facility in Kongsberg, Norway.
Control is effected by means of flaperons
mounted on the wing trailing edges.
The Moog system controls all of the primary flight surfaces including ailerons, flaperons
, elevators, rudder, flight spoilers and horizontal stabilizer.
Boeing has contracted India's Hindustan Aeronautics (HAL) to manufacture the flaperons
that will be used on its 777 series of aircraft ordered by the country's airlines.
Moog is partnered on this program with Parker Hannifin to jointly provide the Electro-Hydrostatic Actuation System that will control the aircraft's major flight surfaces including the flaperons
, rudders, and horizontal tails.
