Flap Torque Tube/Pushrod Distortion Inspection - Piper 6X Maintenance Manual

(6) Adjust flaps to neutral:
(a) Using the flap rigging tool shown in Figure 3. (See 95-00-00, Figure 6, for fabrication
instructions.)

(b) Alternatively, adjust each flap push rod so that the chord line of the flap forms a zero (0°)
degree ± 1° angle with the wing chord at the outboard end of the flap. This check is made
with a light pressure on the underside of the flap to remove slack in the linkage.
NOTE: In the event of wing heaviness during flight, the flap on the side of the heavy wing can
be adjusted down from neutral to remedy this condition by lengthening the control rod.
Check the inspection hole in each rod end to ascertain that there are sufficient
threads remaining and a wire cannot be inserted through these holes. Do not raise the
flap of the other wing above neutral.
(7) Measuring from the neutral position obtained from Step 6, and maintaining the light up
pressure on the underside of the flap, check flap down travel, which should be 10 ± 2 degrees
at first notch, 25 ± 2 degrees at second notch and 40 ± 2 degrees at third notch. Readjust the
torque tube screw in or out as required. After any readjustment of the screw it will be
necessary to review Steps 3 thru 6.
(8) Check complete operation of the flaps, and handle and ratchet mechanism.
(9) With flaps correctly adjusted, perform Stall Warning System, Functional Tests, Ground,
27-30-00, to verify correct adjustment of the flap position switch (see Figure 4). If flap position
swtich requires adjustment:
(a) Loosen adjusting screw.
(b) Set switch to activate when flaps are set to the 25 degree position.
(c) Tighten adjusting screw.
(10) Install all access covers removed.
NOTE: The flap adjustment must be complete before starting aileron adjustment.

Flap Torque Tube/Pushrod Distortion Inspection

If flaps have been extended at or above V
evidence of distortion.
A. If the paint is cracked or peeling anywhere along the torque tube arm or pushrod, torsional
movement has occurred.
B. Remove the paint and inspect for cracks:
(1) In the welds at the arm on the torque tube end.
(2) In the rod ends and pushrod tube.
(3) Use a dye penetrant method of inspection.
C. If cracks are not found, repaint the part(s) and reinstall.
D. If cracked, replace the affected part(s).

MAINTENANCE MANUAL
Place a flap rigging tool as shown in Figure 3 against the underside of the wing and
flap as close as possible to the outboard end of the flap without contacting any rivets.
The tool must be positioned parallel with the wing ribs, with the aft end of the tool
even with the trailing edge of the flap.
With the flap control rods connected between the torque tube crank arm and flaps:
check that the surface of the wing contacts the tool at its forward surface and at the
spacer, and the aft end of the flap contacts the aft end of the tool. Maintain a light
pressure on the underside of the flap to remove slack in the linkage while making this
check.
, inspect the flap torque tube arms and pushrods for
