A. Flap Rigging - General

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.

C. Position of the Forward and Main Eccentric Bearings (Outboard Flap)

Main Eccentric Bearing - Adjustment, Track 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. A red paint mark on each bearing and fitting shows the zero datum position. The bearings are at the zero datum position when the red paint marks on the bearing and fitting 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.
(c) If your aircraft is post modification 35900 and you find an asymmetrical offset value at the label (41) at track 3:
Do NOT adjust the forward eccentrics to the asymmetrical offset value (label 41 at track 3) at this time.
(2) On the carriage bolts (58) at the track 3 and track 4 positions:
(a) Remove and discard the cotter pin (54) from the nut (53).
(b) Remove these items:

the nut (53)
the crushable spacer (52)
the nut (55) and the washer (56)
the locking plate (51).

(3) Remove and discard the lockwire from the nuts (57) installed on the failsafe hooks.
(4) Loosen the nuts (57).

NOTE: These are loosened to give easier movement when the eccentric bearings are adjusted.

(5) At the track 3 and track 4 positions:
(a) Engage the 98D27504082000 TOOL - FLAP ADJUSTING, TRACK 4 with the splined bush in the flap carriage.
(b) Turn the splined bush until the red paint marks are aligned. Adjust the bearings at one track position and then the other in small equal increments.

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

(1) Use the TOOL FLAP ADJUSTING to adjust the main eccentric bearings. Carefully adjust the two bearings at the same time in small, equal increments.
(2) At track 3 and track 4, adjust the main eccentric bearings until:

the top surface of the flap trailing edge aligns with the scale block (20) as follows:

(a) At track 3:
1 On flap arm 3, find the label (43) and read the value on the label (43).
2 Align the top surface of the flap trailing edge with this value on the scale block (20).
This value has a tolerance of +/- 1 mm (0.039 in.).

NOTE: You must look inboard from the outside of the flap track beam when you read the scale block.

3 If there is no value shown on the label (43), or there is no label attached to the flap arm:

align the top surface of the flap trailing edge with the zero mark +/- 1 mm (0.039 in.) on the scale block (20).

(b) At track 4:
1 On flap arm 4, find the label (43) and read the value on the label (43).
2 Align the top surface of the flap trailing edge with this value on the scale block (20).
This value has a tolerance of +/- 1 mm (0.039 in.).

NOTE: You must look inboard from the outside of the flap track beam when you read the scale block.

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

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

(1) If you find an asymmetrical offset value on the label (41) at track 3, it is necessary to adjust the forward eccentrics at the tracks 3 and 4.

NOTE: The label (41) shows the asymmetrical offset value. This is the adjustment applied to the forward eccentric bearings 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) Adjust the forward eccentrics at track 3 and track 4 in sequence (in small increments).

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

For details refer to the task 'Adjustment of the Forward Eccentrics' (Ref. AMM TASK 27-51-00-820-004).

2 For a (-) or (down) value, the top surface of the flap must align (+/- 1.0 mm (0.0394 in.)) with:

the line below zero on the scale block (20) which is the same as the label value.

NOTE: The scale block has 1 millimeter graduations.

(b) At the outboard end of the flap measure the dimension N (the vertical distance between the outer fixed shroud and the top surface of the flap):
1 For a (+) or (up) value, the distance must be zero +/- 1.0 mm (0.0394 in.) plus the value shown.
2 For a (-) or (down) value, the distance must be zero +/- 1.0 mm (0.0394 in.) minus the value shown.

NOTE: The label (41) shows the asymmetric offset value. This is the adjustment applied to the forward eccentric bearings 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 27-54-62-400-001).
(4) At tracks 3 and 4, remove the parts of the 98D27504038001 KIT-FLAP RIGGING:
