(l) Ensure flap exhibits a 32° angle change. If flaps are not set at 100% deployed 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 down proximity sensor by loosening screw and repositioning on flap
actuation extension tube.
3
Turn flap switch to 100%.
4
Repeat step (i) until flaps are in 100% deployed position.
(m) Turn flap switch to UP. After flaps stop, turn flap switch to 50%.
(n) Ensure flap exhibits a 16° angle change. If flaps are not set at 50% deployed position
adjust the flap actuator proximity sensor as follows:
1
Turn flap switch to 100%
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 half down proximity sensor by loosening screw and repositioning on flap
actuation extension tube.
3
Turn flap switch to 50%.
4
Repeat step (k) until flaps are in 50% deployed position.
(o) Remove inclinometer from flap.
(p) Install carpet and access panels CF4C and CF5. (Refer to 6-00)
(q) Install passenger compartment seats. (Refer to 25-10)
(2) Inspection/Check - Flap Rigging (See Figure 27-502)
Note: If the following flap leading edge gap and overlap inspections do not fall within the
specified clearances, contact Cirrus Design Customer Service Department for dis-
position.
(a) Acquire necessary tools, equipment, and supplies.
(b) Using 90° square with flaps fully extended, verify maximum gap between crown of flap and
trailing edge of wing is 0.965 inch +/- 0.300 (2.50 cm +/- 7.6 mm) at root of the flap, and
0.843 inch +/- 0.300 (2.10 cm +/- 7.6 mm) at tip of flap.
(c) Using 90° square with flaps fully extended, verify maximum overlap between leading edge
of flap and trailing edge of wing is 1.475 inch +/- 0.300 (3.80 cm +/- 7.6 mm) at root of flap,
and 0.813 inch +/- 0.300 (2.10 cm +/- 7.6 mm) at tip of flap.
(d) Verify flap UP, 50%, and 100% deployment positions. (Refer to 27-50)
(e) Verify minimum rod end thread engagement of 0.312 inch (0.79 cm).
(f) Verify 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).
