F. Flap Adjustments and Inspections
(1) Adjustment/Test - Flap Travel
(a) Acquire necessary tools, equipment, and supplies.
Note: Flap may exhibit a slight twist from root to tip. Average the inboard and out-
board angle to set the neutral point.
(b) Remove passenger compartment seats. (Refer to 25-10)
(c) Remove carpet and access panels CF4C and CF5. (Refer to 6-00)
(d) Adjust flap actuator end fitting engagement length:
1
Airplane S/N 1005 - 1034; ensure minimum engagement length of flap actuator end
fitting to flap actuator rod is 0.250 inch (0.635 cm).
2
Airplane S/N 1035 and subsequent; adjust the flap actuator end fitting so that the
flap actuator and the rod end connected to the torque tube coupler are installed to a
depth between the end fitting inspection holes.
(e) Turn MASTER SWITCH to ON.
(f) Turn flap switch to UP.
(g) Mark WS 132 reference line for left and right wing templates as follows:
1
From wing cuff, measure 1.75 inches inboard and mark.
2
From flap outboard edge, measure 10.7 inches inboard and mark.
3
Draw WS 132 reference mark line from leading edge to trailing edge.
(h) Mark WS 40 reference line for left and right wing templates as follows:
1
From flap inboard edge, measure 1.75 inches outboard and mark.
2
From wing cuff, measure 90 inches inboard and mark.
3
Draw WS 40 reference mark line from leading edge to trailing edge.
(i) Position WS 40 and WS 132 template on left and right wing to verify flaps are in full up
position. If flaps are not set at full up position adjust the flap actuator proximity sensor as
follows:
1
Turn switch to 50%.
Note: For best results in determining proximity sensor location, do not move
sensor more than 0.10 inch (2.5 mm) per positioning attempt.
2
Reposition full up proximity sensor by loosening screw and repositioning on flap
actuation extension tube.
3
Turn flap switch to UP.
4
Repeat step (f) until flaps are in full up position.
(j) Fasten inclinometer to inboard side of left flap and set at 0°.
(k) Turn flap switch to 100%.
