5. Flap System Adjustment
(PIR-PPS50056-2. Rev. P.)
Use the following procedure to adjust flap system:
A. To align flaps within one (1) degree of each other, adjust the inboard rod end on either the left or
right pushrod assembly (i.e. - 82977-2, Figure 3).
NOTE: Maintain a slight up pressure on the underside of the flaps when checking flap travel.
B. The outboard rod end of the pushrod 85097-2 (see Figure 2) bolts to a slot in the cam assembly. To
increase flap travel, move that rod end forward in the slot. To decrease flap travel, move that rod end
aft in the slot. Adjust rod end as required to allow the cam assembly to activate the warning horn
switch.
NOTE: It is acceptable to have up to 3/16th inch vertical end play at flap trailing edge in the 0° flap
position, measured at center of flap track.
C. After any adjustment to the flap system, check for proper operation. See Caution under Rigging.

(PIR-PPS50056-2. Rev. P.)
A. Rig the flaps as described above.
B. Place the airplane on jacks and fully retract the landing gear.
C. Place flap handle in 10° position. Flaps shall extend to first mid position and landing gear warning
horn does not sound.
D. Place flap handle in 20° position. Flaps shall extend to second mid position and warning horn
sounds.
E. Place flap handle in full down position. Flaps shall extend fully, and warning horn sounds.
F. Place flap handle in full up position. Flaps shall travel to up position and warning horn should stop
sounding.
G. Extend landing gear until fully down and locked. Remove airplane from jacks.
H. Move flap handle thru 10°, 20° and full down position, the warning horn should not sound. Check
the flap indicator to confirm the indicator correctly follows the flap handle and correctly displays the
appropriate flap position.
