_______________________________________________
1. General_______
A. Each trailing edge flap consists of a midflap, a foreflap and an aftflap. The three flap segments are mechanically separated during flap extension. Each trailing edge flap is supported by two flap carriages which travel on tracks mounted under the wing.
2. Midflap_______
A. The inboard midflap consists of ribs, three spars, a honeycomb trailing edge and clad aluminum skins. A hinged flap segment is attached to the outboard trailing edge of the midflap. Four tracks mounted on the rear spar of the midflap support the aftflap.
B. The outboard midflap consists of ribs, two spars, a trailing edge beam, two honeycomb trailing edge panels and clad aluminum skins. Four tracks mounted on the rear spar protrude through the trailing edge beam to support the aftflap.
3. Foreflap________

LEADING EDGE FLAPS - DESCRIPTION AND OPERATION
______________________________________________
1. General_______
A. Two Krueger-type leading edge flaps are installed on each wing. The flaps are numbered 1 through 4 from left to right. Each flap is a machined aluminum casting containing integral ribs and stiffeners. Each flap has four gooseneck hinges which attach to fittings in the leading edge of the wing. A centrally located fitting is also provided on each flap for connecting the flap to a hydraulic actuator. A hinged fairing is installed on the trailing edge of each flap. The fairing extends the full length of the flap on leading edge flaps 2 and 3 and approximately the inboard 70 percent on flaps 1 and 4.
