4. Procedure
Subtask 27-51-00-820-084-A ** ON A/C NOT FOR ALL

A. Flap Rigging - General Information

Flap Rigging - General ** ON A/C NOT FOR ALL

Eccentric Bearings - General ** ON A/C NOT FOR ALL

(1) General:
(a) The position of a correctly rigged flap gives the correct relation between:

the flap trailing edge
and
the top surface of the wing.

In this position the correct aerodynamic conditions for the best flight performance are set.
(b) To rigg the flaps correctly, eccentric bearings in the attachments at the flap tracks are adjusted.
At each track there are two eccentric bearings:

the main eccentric bearing
the forward eccentric bearing.

(2) Main eccentric bearing:
The main eccentric bearing is the spherical bearing at the flap carriage attachment and is used for standard rigging. Movement of this bearing causes the complete flap to move vertically in relation to the wing.
You adjust the height of the complete flap.
(3) Forward eccentric bearing:
The forward eccentric bearing is on the flap drive-arm and is adjusted only for asymmetric rigging conditions (if this aircraft has an asymmetric rigging value.
For more information refer to ISI 27.54.00002.
You adjust only the trailing edge of the flap that means the trailing edge moves vertically.

D. Positions of the Forward and Main Eccentric Bearings (Outboard Flap)

Label Position - Flap Track 3 ** ON A/C NOT FOR ALL

Main Eccentric Bearing - Adjustment Tracks 2, 3 and 4 ** ON A/C NOT FOR ALL

NOTE: The main eccentric bearings are spherical bearings installed in the flap attachment fittings at the flap carriages. Red paint marks on the bearings and on the fittings show the zero datum position. The bearings are at the zero datum position when the red paint marks are aligned.

(1) Before you set the main eccentric bearings to the zero datum position:
(a) Make sure that the forward eccentrics are in the zero datum position (Ref. AMM TASK 27-51-00-820-004).

NOTE: The forward eccentrics are in the zero datum position if the punched/painted marks on the forward eccentrics align.

(b) If these marks do not align, adjust the forward eccentrics to the punched/painted marks.

NOTE: If you find an asymmetrical offset value at the label (100) at track 3 (post modification 22019):
Do NOT adjust the forward eccentrics to the asymmetrical offset value (label 100 at track 3) at this time.

(2) On the carriage bolts (108) at the track 3 and track 4 positions:
(a) Remove and discard the cotter pin (105) from the nut (104).
(b) Remove these items:

the nut (104)
the crushable washer (103)
the nut (106) and the washer (107)
the locking plate (102).

(3) Adjust the bearings at one track position then the other in small equal increments:
(a) At the track 3 position:
1 Engage the 98D27504081000 TOOL - FLAP ADJUSTING, TRACKS 2 AND 3 with the splined bush in the flap carriage.
2 Turn the splined bush until the red paint marks are aligned.

NOTE: The splined bush engages with the main eccentric bearing. When the bush is turned the eccentric bearing also turns.

(b) At the track 4 position:
1 Engage the 98D27504082000 TOOL - FLAP ADJUSTING, TRACK 4 with the splined bush in the flap carriage.
2 Turn the splined bush until the red paint marks are aligned.

NOTE: The splined bush engages with the main eccentric bearing. When the bush is turned the eccentric bearing also turns.

G. Complete the Adjustment (Rigging) of the Outboard Flap

Label Position - Flap Track 3 ** ON A/C NOT FOR ALL

Rigging Dimensions - Outboard Flap ** ON A/C NOT FOR ALL

(1) If you find an asymmetric offset value on the label (100) at track 3, it is necessary to adjust the forward eccentric bearings at the tracks 3 and 4.

NOTE: The label (100) shows the asymmetric offset value. This is the adjustment applied to the forward eccentric bearing in the flap drive strut at tracks 3 and 4. The adjustment is necessary on some aircraft to give the correct aerodynamic balance:

a plus (+) or (up) value shows that the flap trailing edge must be moved up.
a minus (-) or (down) value shows that the flap trailing edge must be moved down.
a zero (0) value shows that no adjustment is necessary.

(2) At tracks 3 and 4:

Do the adjustment of the forward eccentrics (Ref. AMM TASK 27-51-00-820-004).

(3) After the adjustment: Safety the forward eccentrics (Ref. AMM TASK 27-54-62-400-002).
(4) At tracks 3 and 4, remove the 98D27504113001 KIT - FLAP RIGGING:
(a) Remove the scale block (80).
(b) Remove the pin (82) and remove the fin (81) from the base assembly (83).
(c) Loosen the knurled screws (87) and remove the base assembly (83) from the flap track beam (88).
(5) Measure the clearance of the flap guide-roller and adjust if necessary (Ref. AMM TASK 27-54-63-400-001).
