3. Job Set-up
Subtask 27-21-41-941-055-A

A. Put a WARNING NOTICE(S) in position to tell persons not to operate the flight controls.

Subtask 27-21-41-010-053-A

B. Get Access

NOTE: You can do the inspection of the hinge fittings no. 1 thru 5 and no. 7 for wear without removal of the rudder.
It is also possible to do the measurement of the related items at the hinge fitting no. 6 but the access on the installed rudder is very difficult.
AIRBUS recommends the removal of the rudder to do the inspection on hinge fitting no. 6.

CAUTION: MAKE SURE THAT YOU REMOVE ONE HINGE BOLT OR ONE RUDDER SERVO-CONTROL ATTACHMENT-BOLT AT A TIME. IF YOU REMOVE MORE THAN ONE BOLT AT THE SAME TIME, DAMAGE TO THE RUDDER AND THE VERTICAL STABILIZER HINGE ARMS CAN OCCUR.

(1) If you do the inspection on the installed rudder:
Make sure that you only remove one hinge bolt or rudder servo-control attachment-bolt at a time.
(2) Get access (for the inspection of hinge fittings no. 1 thru 5 and no. 7 at the installed rudder):
(a) Put the ACCESS PLATFORM 12M (40 FT) - ADJUSTABLE in position.
(b) Remove the access panels 325BL 325BR 325CL 325CR 325DL 325DR 325EL 325ER at the trailing edge of the vertical stabilizer (Ref. AMM TASK 55-33-13-010-002).
(c) Remove the access panels 325AL 325AR (Ref. AMM TASK 53-55-12-000-001).
(d) Open the access door 312AR.
(3) Get access (only for inspection of hinge fitting no. 6):
(a) Remove the rudder (Ref. AMM TASK 27-21-41-000-001).

G. Measurement of the Fits and Clearances of the Rudder Servo Control Attachments
(1) Refer to the 'Check of the rudder servo control attachments' to do the measurement of the fits and clearances of all the rudder servo control attachments (Ref. AMM TASK 27-24-51-200-001).

NOTE: If you have removed the rudder, it is only necessary to do the check of the related attach fittings on the rudder side and the related actuator arm which is attached to the rudder.
If you also want to measure the VTP side, remove the rudder servo controls to do the complete measurement which is given in the task 'Check of the rudder servo control attachments'.

(1) Make sure that the inner dimension of the bearings (15), (16) and (19) is between 14.2748 mm (0.5620 in.) and 14.2875 mm (0.5625 in.).
(a) If the dimension is not correct:
1 Replace the rudder hinge-arm attach-fitting(s) SRM 553642.

NOTE: As a result of in-service experience, AIRBUS recommends that you replace also the related attachment parts (also if they are in the in-service wear limits). This will prevent rudder vibration.

(2) Make sure that the inner dimension of the bushes (17) is between 19.037 mm (0.7495 in.) and 19.058 mm (0.7503 in.). If the dimension is not correct, replace the bushes (17).
(a) No wear is permitted.
(3) Make sure that the inner dimension of the bushes (18) is between 29.000 mm (1.1417 in.) and 29.033 mm (1.1430 in.).
(a) If the dimension is not correct:
1 Replace the rudder hinge-arm attach-fitting(s) SRM 553642.

NOTE: As a result of in-service experience, AIRBUS recommends that you replace also the related attachment parts (also if they are in the in-service wear limits). This will prevent rudder vibration.

(4) Make sure that there is no play between the bushes (17) and the bushes (18) in the hinge arm.
(a) No play is permitted.

I. Measurement of the Rudder Hinge Fittings

Fits and Clearances of the Rudder Hinge Fittings

NOTE: As a result of in-service experience AIRBUS recommends that you replace the related attachment parts (also if they are in the in-service wear limits). This will prevent rudder vibration.

(1) Measure the axial play between the bushes (10) and their related bolts (30) at each of the rudder fittings.
(2) Make sure that the axial play is a maximum of 0.158 mm (0.0062 in.).
(3) Make sure that the bolts (30) have a minimum diameter of 14.20 mm (0.5591 in.).

NOTE: If the axial play is less than the given limit, the bolts (30) can have a minimum diameter of less than 14.20 mm (0.5591 in.).
