(7)
Tighten the bolts (20) sufficiently to hold the duct in position. Do not torque the bolts at this time.
(8)
Make sure that the fifth stage elbow duct (25) is in the correct position.
(9)
TORQUE the coupling nut as follows:
(a)
TORQUE the coupling nut to the value shown on the coupling.
(b)
Tap the perimeter of the coupling with a fiber hammer, then torque the coupling nut again.
(c)
Do the torque procedure two times, then torque the coupling nut again.
(10)
TORQUE the bolts (20) to between 90 and 120 lbf.in (1.01 and 1.35 m.daN).
(11)
Safety the bolts (20) with lockwire 0.032 in. (0.8 mm) dia (Material No. CP8001) or lockwire 0.032 in. (0.8 mm) dia (Material No. CP8002).

B. Preparation for the leak test
(1) There are two possible procedures to find the location of a pneumatic joint air leak.
NOTE : Apply dry developer only on the connections of the removed
____ pneumatic components.Do not apply dry developer on all the pneumatic components.
You can apply developer, dry (Material No. CP3010) around the
pneumatic joints or you can install FOIL-ALUMINUM (Local Purchase)
around the pneumatic joint locations.
Do the steps that follow to apply foil, aluminum to the pneumatic
joint locations.
(a)
Wind the foil wrap around the joint one time.
(b)
Twist the seam of the foil wrap tight.
(c)
Make the foil wrap as tight as possible on the tube, but do not rip the wrap.

(d) Attach the foil wrap with safetywire 0,024in. (0,6mm) (Material No. CP8004) on the two sides of the pneumatic joint.

C. Close Access
(1)
Make sure that the work area is clean and clear of tool(s) and other items.
(2)
Close the left thrust reverser door (Ref. TASK 78-36-00-410-040): FOR 1000EM1 451AL, 452AR FOR 1000EM2 461AL, 462AR

D. Make the thrust reverser serviceable (Ref. TASK 78-30-00-081-041). Subtask 36-11-49-865-139
E. Remove the safety clip(s) and the tag(s) and close this(these) circuit breaker(s): 2HA1, 2HA2, 3HA1, 3HA2
Subtask 36-11-49-860-087
F. Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only)
(Ref. TASK 31-60-00-860-001).
Subtask 36-11-49-720-061
G. Do this Test
(1)
on the ECAM control panel 11VU, push the BLEED key (on the lower ECAM DU, the BLEED page comes into view).
(2)
On the lower ECAM DU, on the BLEED page:
-Make sure that the related HP bleed valve is shown closed.
(3)
Start the related engine with the automatic or manual start procedure (Ref. TASK 71-00-00-710-003) or (Ref. TASK 71-00-00-710-004) and keep it at idle.
(4)
On the AIR COND panel 30VU:
-Push the ENG 1(2) BLEED pushbutton switch (OFF legend goes off).

(5) After 5 minutes, on the lower ECAM DU, on the BLEED page:
-Make sure that the related HP bleed valve is shown open.
(6) Stop the engine (Ref. TASK 71-00-00-710-028). Subtask 36-11-49-040-110
H. Make sure that the thrust reverser is unserviceable (Ref. TASK 78-30-00-481-041).
Subtask 36-11-49-010-145
J. Open the left thrust reverser doors (Ref. TASK 78-36-00-010-040).

Subtask 36-11-49-080-056
K. Make sure that there are no leaks at the junction between the HP bleed valve and the duct on the related engine.
NOTE : There is a leak when the foil installed on the duct breaks or when
____ it is too hot. There is a leak when the leak air removes the dry developer from the junction.
(1) Remove the materials used to do the leak test.
