(5) Adjustment/Test - Roll Trim Cartridge
(a) Acquire necessary tools, equipment, and supplies.
(b) Remove MFD. (Refer to 34-40)
(c) Insert lock-out pin at aileron actuation pulley in center console.
(d) Remove LH aileron. (Refer to 57-50)
CAUTION: To prevent damage to trim motor, set adjustment screws on limit switch
stops all the way in to limit the travel of the motor to minimal rotation.
(e) Fasten inclinometer to RH aileron and set at 0°
(f) Remove lock-out pin.
(g) Adjust trim cartridge length to allow 6° +/- 1° aileron trim deflection:
1
If required, adjust initial length of trim cartridge to 9.4 inches (24.1 cm).
2
To increase RH aileron trailing edge up movement (LH aileron trailing edge down),
lengthen trim cartridge by loosening jam nut and turning rod counterclockwise.
3
Shorten cartridge for opposite results.
4
If additional travel is required, adjust trim motor adjustment screws.
(h) Verify trim cartridge minimum rod end thread engagement of 0.312 inch (0.792 cm).
Tighten jam nuts.
(i) Perform Roll Trim Cartridge Inspection/Check. (Refer to 27-10)
(j) Install LH aileron. (Refer to 57-50)
(k) Install MFD. (Refer to 34-40)
(6) Inspection/Check - Roll Trim Cartridge
(a) Acquire necessary tools, equipment, and supplies.
(b) Verify correct aileron system rigging. (Refer to 27-10)
(c) Fasten inclinometer to left aileron and set at 0°
(d) Verify roll trim cartridge is adjusted to hold ailerons in neutral position +/- 1°.
(e) Run trim motor to full right and full left bank trim positions and verify 6° +/- 1° aileron trim
deflection. If roll trim is out of adjustment, perform Roll Trim Cartridge Adjustment/Test.
(Refer to 27-10)
(f) Verify that at full aileron trim travel (+/- 6°), the aileron-rudder interconnect bungee does
not get tensioned.
(g) Remove inclinometer.
(h) Verify positive clearance between trim cartridge and actuation pulley under full range of
trim motor positions.
