Two girders, made from pressed aluminum alloy sheet, add strength to the structure and attach the top and the bottom skins to the spar. The top girder is corrugated to let air from the anti-icing system flow through to the bottom skin.
There are seals attached to the rear face of the slat:
-at the inboard end of the slat
-around the tracks
-near the forward joint of the top and bottom skins.
Elbow pieces reinforce the seals at each corner.
A weather-seal strip closes the area between Slat 4 (Ref. 57-45-00) and Slat 5. The strip is installed in parallel channels attached to the rear face of the top skin of the slats.
B. Trailing Edge Structure
The slat 5 has a trailing edge structure which is attached to the the main rivetted structure at the rear spar. It closes the aft edge of the slat and completes the aerodynamic profile.
The trailing edge is a bonded structure of aluminum alloy panels with a honeycomb core.
C. Slat Tracks
The slat 5 is connected to slat-tracks 11 and 12. Each slat-track is made from a curved steel forging and has a rack attached by bolts to its bottom face. A pinion on the slat-track actuator turns to move the rack and thus extends or retracts the slat. Fixed stops at the ends of the slat-track limit the travel of the slat.
The slat-tracks are connected to the track ribs of slat 5 with bolts, nuts and titanium alloy links. A closing plate and self-aligning bearings are attached to the forward end of each slat-track. Eccentric bushes are installed in the slat-track ribs for adjustment of the slat.
D. Attachments for the Wing Anti-icing System
A piccolo tube goes through the slat ribs from the inboard end, and is closed at the outboard end. It is connected to the outboard end of Slat 4 by a flexible hose. The slat top girder is corrugated to let the air from the piccolo tube flow through the exhaust holes in the bottom skin.
